KiloVault HAB 48V 7.5kWh Lithium Battery 

This is good compared to Tesla Powerwall 2 at 13.5 kWh (with 10 yr warr to 70%, 90% roundtrip efficiency) for $12K = $888/kWh (please feel free to correct my numbers if incorrect)

Yeah, If you don't care that we are draining our deep water aqua-firs, that take thousands of years to refill, and raiding poor nations for their natural resources. Hey, wait,, its like the oil rush, all over again. We haven't learned a thing. Humans are so stupid, don't care what they destroy, as long as they are not the one paying the price, it will by our children's children who pay the price. No,, the salt water battery was a much better idea, you know, for a person who actually cares about the long term effects on the planet and the life on it. When your dollar is the most important thing, there is something wrong with you.

And it gets better. I just purchased a Chinese version with 10-year warranty. 10kWh for $3800. That is $380 per kWh I believe.

@@stevebakker6884 , no chi-com company will be around in ten years to honor it.

Will's fantastic, isn't he? We are talking with him about testing some KiloVault batteries, but not this one yet.

@@AltEStore awesome that some of my favourite renewable self powered RU-vid channels talk to each other :)

Don’t fear getting an honest tare down and review from Will Prowsse. He won’t let us down.

Will is the man!

I'd be careful about sending one to Will. I think he's on the battle born payroll.

Yes, exactly right. Doubling the batteries would double the kWh, charge and discharge rates, and surge.

Good

Most electric cars use lithium ion batteries, whereas this uses LiFePO batteries that have no explosion risk, cost more, but last much much longer than the lithium ion technology. Worth it.

Such a common misconception, the car batteries last less than half as many cycles and don't have the same type of error forgiving chemistry of Lifepo4. Lifepo4 can be had for under half that $600 per kWh, but often times with less quality control. If you're expert enough to monitor them such quality control isn't as crucial but 99% of people lack such an aptitude.

It should run longer without invertor loss convert from DC to AC

One cycle is full charge, down to 80% DOD (20% remaining) and back to full charge. The useful life will be negatively affected by discharging beyond 80%, but LFP batteries are very tolerant of living in a partial discharge state (unlike lead based batteries (FLA, AGM, Or GEL).

No way to say without knowing how much energy your air conditioner is using. If the unit is 120V 60Hz, and is under 1875W, you could plug it into a Kill A Watt and monitor its actual use. www.altestore.com/store/meters-communications-site-analysis/meters-battery-monitors/power-meters/kill-a-watt-electricity-usage-meter-p4400-p932/

Yes it does. The BMS shuts off charging at 32F (0C).

Are you talking 65Vmp or 65Voc? For a 48V battery, you want at least 68Vmp or 88Voc.

I can't answer that question but it's a good one, most LiFePO4 prefer upright but don't demand it, it's just to keep internal pressures and expansion off the lead ports. If I were to guess correctly and I bat a good percentage, I'd say laying down if not pushed to their whole 7kw at once would be safe. Thermal expansion usually happens when they are charged or discharged quickly especially while outside their temperature range. If you did .5C, 3750 watts output I'd say anything but directly upside-down would make it through the 4,000 cycles. And my name isn't du fung it's Brent. It's a joke between me and friends.

It's kinda odd to me personally anything but pure sine is still ran, they're pretty cheap anymore.

No. This battery is rated at 150A at 50 Vdc. Your welder is rated for 150A AC (presumable 240 Vac). You can expect 60A @ 120 Vac or 30A at 240 Vac. Your real limiting factor however, will be your inverter......very few inverters are capable of 150 A @ 240 Vac.

@@jerrym2321 Its 380Vac so its the 3 phase model(Scandic region)

Yes if you are using a 1/8 inch rod at about 100 amp setting. It won't do a 3/16 inch rod. My Lincoln 225 draws about 30 amps /230 volts using a 1/8 inch rod.

You can see the latest pricing and specs at www.altestore.com/store/deep-cycle-batteries/lithium-batteries/kilovault-hab-75kwh-lithium-battery-storage-system-p41420/. A 48V 1000Ah battery would be huge, over 6 times the size of this. A practical solution is to buy multiple of the HAB 7.5 batteries, and wire them in parallel to achieve the required battery bank size.

It is a 150Ah battery, with a max charge rate of 120A. 150Ah / 120A = 1.25 hours to charge from empty.

Must not be or someone would have been bragging about it by now! Wow! $5000 and no low temp cutoff?!

You can simply stack 2 or more of the HAB together to build the size battery you need.

Living off-grid generally requires changes to lifestyle. Anything that makes heat or cold uses a lot of energy. So you need to look at heating and cooking alternatives instead of electricity, and get the most energy efficient fridge possible. Paying more to get an expensive fridge can save you money by needing a smaller solar system to power it. Same with determining if you need air conditioning. You must take a look at all of your electric needs, create a loads list to determine how much energy you need, and then it can be determined how big of a system you need. Simply taking a traditional American household off-grid without dramatic changes can be extremely expensive.

The box I assume is full, so far as panels that depends on how fast you need to recharge it. To charge it once to full a day, 3kW of solar would probly manage that on most the planet even with just a couple hours of Sun a day. In Arizona where they get 5hours a day, 1.2kwh could manage it.. and the last "How much?" maybe you mean the cost, if you know how to get nice used panels made less than 10 years ago, 3kw can cost like $960 ;P but you have to know your shit a bit as I do. I bought 3.3kwh for 960 exactly thats including tax and the panels were 8 years old into their 25 year warranty over 80% original output.

Not apples to apples. Tesla is an NMC battery, but the Powerwall 2 has about twice the capacity (14 kWh)

Thanks for sharing the details of your system. Sounds like a great setup, I love hearing about people's real world usage.

It doesn't currently have UL listing, so check with your AHJ if the batteries need it or just the equipment toughing the grid.

We have no plans to make a 24V version at this time.

The limitation is the capability of the lithium cells, the way around it is to have more cells to share the load. Simply connect two batteries in parallel to support a 12kW inverter.

Actually the opposite is true. If you compare the HAB with the KiloVault HLX1800, the smaller 1800Wh battery is $0.72/Wh, while the larger HAB, with more features, is $0.68/Wh.

altE Store ok, good to know, thanks!

It can be discharged to 0, but for longer life, 80% is recommended. Just like lead acid can go down to 50%, but 30% is better.

@@AltEStore ummm... Just like lead acid can go down to 30% but 50% is better. 🙃

@@justfly2525 we are probably using different terms. Lead acid can go down to 50% depth of discharge, but on a regular basis shouldn't go much below 30% depth of discharge, or 70% state of charge.

@@AltEStore Oh, you said "Just like lead acid can go down to 50%, but 30% is better." 30% dod is better for what? Certainly not for the battery. You guys have a great website btw. Probably my favorite site to peruse!

@@justfly2525 only using 30% of a lead acid battery is healthier for the battery than using 50% of it. You will get many more cycles out of it the less you use.

This product is not designed to handle the vibrations occurred during travel. We recommend it be used for stationary applications only.

@@AltEStore Yes, I thought they might be. Still, your product still seems to be of good quality and robust enough to supply off gridders with abundant free energy. Thank you for your quick response.

The price go tear pocket

U must be rich I'll say. They are very expensive in deed

Apartd from being an engineer..i know a lot about solar energy sir

Wow! That's heavy, and that cable is massive. Was thinking about it for RV until it mentioned the weight.

@@sohappytosew1082 weights not really an issue for me, my 5th wheel maxed out is 36k and if can replace all the lead acid batteries with this setup and be 100% off grid I'd be interested..

@@XaviarJS, that would be great! I'm looking into either lithium or golf cart batteries to replace my 6v AGM's.

The battery is designed for stationary applications. It isn't designed to handle the vibration of an RV.

@@AltEStore , makes sense. Thanks!

Thanks for liking.

If you do the math and compare it to lead acid type batteries it's actually cheaper.

@@FND1337 lol I'm sure you're wrong since you can have a 7.5kwh lithium iron phosphate battery for less than 2k$ and lead batteries are way cheaper

@@maximeremy6492 Just to give a little hint. You need at least double the battery capacity on lead acid because you only should use like 50 %( if not less) of it's capacity + the lifespan is definitely more compared to standard treated Lead Acid systems. Check out some of Will Prowse Videos on Lithium compared to Lead acid. Hope this helps.

@@FND1337 i was just saying u can have the same capacity for 2000$ if u do the battery yourself. lead acid batteries are crap

@@maximeremy6492 You missed it. Maybe same rating but real world results and durability are not considered with your simple bottom dollar logic.

Frank, many companies that sell batteries, like Batteries Plus, and also some stores like Home Depot, Grainger etc will let you bring in old batteries and drop them off free of charge to recycle. You could also take them to the junk yard and potentially get some money for them by recycling, but currently, this technology, nobody wants the scrap yet so won't take them. This battery will probably last years and years, so hopefully by the time you do need to recycle it, there may be better programs in place to do that. Also, check with your local town. Many municipalities have free Hazmat recycle centers where you can bring in old batteries, old paint, oil,etc to drop off free of charge.

If you use the full 80% each day then it is 11 years till 20% of the battery capacity is gone. Much longer if on some days you only use 30% Someone will use the remaining 80% capacity for another 10 years. Will you still be alive in 20 years?

Sort of. The battery bank in your car is probably 10x bigger than this battery. So you could give a bit of a charge to get to another charging station, but you are not going to fully charge it from 0. Also, the charge rate would be limited to the rating of your inverter, or 30A at 240V, whichever is smaller.

altE Store A Tesla powerwall can though , what’s the difference ?

@@russthomas02 same deal. The Powerwall has 13.5kWh, so it can be used to give your car a partial charge, more than the 7.5kWh from the HAB, but not a full charge.

@@AltEStore don't undersrand. Tesla recommands 2 packs to charge my car. Do you have some doubts about this solution ? Rgds.

@@zwiftfrance two Powerwalls has 27kWh. I don't know how big your car battery bank is, but if it is bigger than that, it'll put whatever it can in. All of this is assuming you are charging at night off the battery alone. If you are charging during the day, it can use solar power, or at night can use what is stored, and use the grid for additional power. The HAB can also be configured to do that, depending on what inverter you use.

Thanks for your concern. I was rather ill last year, but am recovering nicely. Looking forward to making lots of new videos.

If you don't have frequent power outages, you can just go grid tied without batteries.

@@AltEStore I live in texas we don't go with out often but when we do like hurricane Rita 14 days. hurricane Ike 11 days hurricane Harvey 22 days. so I will need batteries.

The only problem with the Powerwall 2 is that you can not charge it with a generator...so not suitable for off grid. And secondly, you need to charge only with AC. So your PV array needs another inverter first before being changed back to DC in the Powerwall, then back to AC. So add the cost of another inverter to the system.

@@vensonata Excellent points... Also Tesla won't let you install anything yourself so that really adds cost for a diy guy. Plus - LG is down to $600 per kw now so after all of the things mentioned in this thread LG beats the HAB and Tesla. I'm a big Tesla fan boy btw. www.solaris-shop.com/lg-chem-resu10h-9-8kwh-primary-lithium-ion-battery/

MAXLEON because Tesla is notoriously slow outside of California and their QC sucks

@@acoatofgold5627 I can certainly understand the first part also for those that already have an inverter and controller. As for the second part that is an opinion or anecdotal unless you have data to back it up.

The beauty is it doesn't need thermal management. The safer LiFePO4 technology eliminates fire concerns. Powerwalls currently can only be installed by certified installers, if they can get one. It gives no option for type of inverter. This allows people to use whatever 48V inverter they want, and they can install it themselves. So the overall installed system price is likely much lower than hiring someone to install a Powerwall.

@@AltEStore Thank you yes and I believe the total installed price for power wall is $10,000 so that makes sense.

All batteries are listed as their total capacity, not usable energy. 100Ah Lead acid batteries can occasionally be discharged to 50Ah, but for better life, shouldn't be used regularly below 70Ah. Likewise, the HAB can be discharge to 100%, but for better life, 80% is recommended. This is true with most lithium batteries. Battleborns are actually rated for 3000 cycles at 100% DoD, 5000 at 80%. The HAB is advertised as 7.5kWh, but actually has a little wiggle room of 7.68kWh.

@@AltEStore I stand corrected on the Battleborn cycle life at 100% discharge, thank you. My point still remains that in my opinion hardware should be labeled per it's practical usage, not so that we need to read the fine print to size a system.

Good point BS1960... But as long as you're comparing lithium to lithium then most all recommend the 80% cut off. So you can still quickly get apples to apples. The LFP-15 can be found with a better warrantied cycle life and at a better price. And LG Chem is even better than it. But do you need all those cycles? Or are years more important? 10 years at one cycle per day is 3650 cycles. I argue that years are more important (depending on application). Price per KW HAB - $667 LFP - $618 LG Chem - $600 Price per 80% rated KW HAB - $833 LFP - $773 LG Chem - $750 Price per warrantied cycle HAB - .2083 cents per cycle LFP - .1289 cents per cycle! LG Chem - Confusing but .0268 cents (at least 60% of life at 10 years w/28,000 cycles or less) HAB - 7.5 year warranty LFP - 10 year warranty LG Chem - 10 years LG Chem is the winner here. Now you have to ask yourself which company you think is still going to be in business in 7.5 to 10 years??? A big company like LG Chem which has better numbers in the first place is the logical answer in my opinion. However, there are lower price per kw out there if you're going to gamble on a small company. I've found numbers as low as $380 (new) per kw and $225 (recycled) per kw. I'm not sure if there's a correct answer here. I personally am going to go with the $225 per kw and gamble away. They only have to last me 3 years and At that point I've paid the same per kw rate as a battery that offers a 10 year warranty up to that 3 year mark. After 3 years I'm saving money. I have reason to believe that battery will last a lot longer than 3 years. Plus... If it does die at the 3 year mark then I'm back in the battery market after prices have fallen for 3 years. I hope this info helps a little. IMO batteries are the most critical decision to make on your system right now. Especially an off grid system like I'm putting together right now. Maybe ALT E Store will start carrying LG Chem for us? I like their store, educational material, and attitude.
