@@TheHybridGuy I installed the new battery. upon replacement I noticed the Nimh connections were corroded so I used Nickel connectors/ nuts. Immediately I notice that my 2008 Prius battery level goes green. The drain is less and my mileage is a little better with better acceleration. All the new cells were 16.46 and one was 16.47 except the special one. Overall, I am very pleased in Texas and looking forward to hitting the mountains and ski slopes.
@@DreamMachineX Doing great. I did find that there was corrosion on the pins of the connector for the ECU and wire harness so I ended up replacing those. But the pack has been great. It can handle long periods of disuse much better than the original.
According to Mr Prius app, our 144v 2012 Prius C nihy pack is still good. Resistance is still fine. I can still get 70 mpg around town. The reason this C2 is still running like new, is low mileage. 27,000 miles!
@@alext8828 Do own a 2012 Prius C? (Not the large type 'heavy' Prius) Because these little cars can get 70 MPG on flat roads, average speeds 25-30 MPH, If you know how to HyperMile them. (44 PSI in tires). If you drive it like a regular car, you will get 40 to 50 MPG. My wife never gets 70 MPG, because she doesn't get off the gas pedal when the car wants to go into EV on a flat road or down a long hill. Don't take my word for it, use Google..
I fill like in winter lithium batteries only dead ballast. They doing nothing. But when temperature is 65-85, they really work. I’m talking about OEM batteries
This is really helpful info! I'm strongly thinking of buying a used Prius V and converting it to a camping/party-mobile. Also as a electricity hub in case of physical disaster - it's basically a generator on wheels, so... 👍🏾
I see you know a lot about prius battery. What are you doing about the over charge? NMHI goes to 80% . I have been tested prius with new nmhi battery and lithium ion battery, MPG increase just a couple more miles, no a big increase.. even if Installing old battery, MPG stays the same. My point for experience, having a new or powerful hv battery doesn't increase much MPG. I had a 2005 prius with plug in battery, and it only increase 8 mpg more. What are you saying has to be tested more.
All the new modules are individually monitored with built-in microchips that allow them to charge up to 97% instead of the standard 70% like on NiMH. 30% of energy with NiMH is lost to heat. With more available energy in this pack, you have increased EV time which translates into MPG. We have thoroughly tested this battery and it is not like the plug-in style you had it just makes your current Prius more efficient.
I'm skeptical. How can the HCM "know" how to condition, charge, and discharge Li-Poly? How can it command it to deliver and accept more current that the MGs were designed to accept and deliver with the Ni-Mh batteries? Put a different way, how can the HCM adjust to completely different parameters? Toyota engineers are pretty smart and I find it hard to believe that the car isn't going to know that something is out of spec with the battery pack, and either return a code or operate in a limp home mode. It makes no sense to me.
I've restored NiMh batteries on many prius's that ive owned. I have many spare battery packs accumulated over the years. I would love to use one spare pack in the void above the spare tire to convert a Gen2 or Gen3 Prius into a plug-in prime that can get 12-25 mph before ICE engine kicks on. can you direct me to someone who can show me how this is possible?
I really want to go this route, sounds really good however, it's $1900 plus shipping for my Gen 2 and the warranty is 2 yr/unlimited miles which for me is under 20k. I can get a brand new Toyota OEM for $1630 here and I will have a piece of mind for the next 10 years (Toyota warranty is 1 yr but it's battery has been proven to last at least 10 years). Can I swap out just one bad module down the line or do I have to buy a whole new pack again due to 1 bad module? Any videos on install for a Gen 2 Prius? If the battery is as good as it claims (not trying to be a smart ass), why not up the warranty instead of just 2 years, Greenbean battery offers lifetime warranty which includes installation and they come out to you. Thanks
Something to put your mind at ease. These lithium batteries are at 7 years with no degradation. You can’t say that about NiMH. That is a great price for a nickel pack but remember it’s old tech. And swapping modules down the road without balancing and proper reconditioning will only lead to failure and you will be fighting it.
Green Bean is a reman battery it will never match the capacity of new. You will spend more time on the phone with warranty and claims to get another installed than enjoying your Prius. Your fuel economy won’t be as good and you acceleration will stink too.
You still never mentioned why you don't offer more then 2 years warranty. That's just like a normal 12V battery warranty which you have to replace every 2-5yrs. I went LifePo4 on my Harley Davidson battery sure it was better then original but 3 times the price and still had to replace it around the same time or just a bit over as original. Also there's a reason why Toyota still uses Nimh in their newer vehicles and backed by 10 years or 150k miles. I would consider this Lithium battery otherwise if it wasn't for the short warranty.
I love it! but I live in Ecuador. I think you can improve the marqueting by sending the modules to Jehu Garcia and William Prowse. They have hundred of thousands of subs. great job.
@@tomaliza5884 Right now the warranty is 2 years unlimited miles. Nexpower is very good about taking care of the customer though. With replacing nickel modules and no balancing you are running on hopes and dreams. it could last, but chances are it won't and you are also not operating at peak efficiency.
@@TheHybridGuy Which Prius do you have? 10 years ago was the Gen 3 in production, so it would have to be a Gen 1 or Gen 2. I still have the original Gen 2 battery in my 2009. 14 years and still going strong. But I have had to replace my 08 RX400h and 10 GS450h.
So, after watching the entire video, do I understand all that I need to do, when I receive the 14 packs for my Prius, is just to install them. There is nothing more that I would need to do? I worry about the balancing. Is there something more that I would need to do in order for these packs to work.
there are different kinds of upgrades. there is the cylindrical green and orange ones and there is the blocks from nexcell. can you tell me what if any difference they may have?
i mean, the only thing i didnt hear mentioned , after showing all the advantages of this kit. the original battery has been known to last 10+ years, up to 15 years and still function. what is the life span of these batteries, the charge discharge cycles the battery is rated for is never listed. how much capacity will this battery have after 2 years, and 1000s of charge discharge cycles? whats are things looking like after 5 years with this battery? i mean there are actually some nice things about the oem battery chemistry not mentioned. i mean if i average 43 mpg on the oem battery, and spend 900 bucks on an oem remanufactured battery, it brings the car to oem specs, and that battery lasts for a good 5 years providing the oem performance during the 5 year duration, and it cost me about 900 bucks. now, i get this lithium battery, at a cost of 2100$ , yea it gets you 53 mpg now or better, so lets math it out. how much gas savings do you get, going from 43 mpg, to 53mpg on average? well there is a diminishing return unfortunately. i mean going from 10 mpg to 20 mpg is an amazing savings. going from 20 to 30 mpg, is a nice savings. going from 30 to 40, yea u still save, but its not as much as u think. and, going from 40 to 50 mpg, just saves u a little bit. point is, does the savings from 43 mpt, to 53 mpg justify the extra cost of the lithium battery? in 2 years time, u may show that u saved enough to justify it. now, what after 5 years? well the oem battery remains consistent , however , until you demonstrate the product after a duty cycle about equal to 5 years of charges and discharges , im betting after that period, the oem battery will be more consistent, with the lithium battery having lost some 30 to 40% of its capacity. if i have to buy a new lithium pack every 5 years, to maintain its performance, calculate savings on the better mpg, now compare an oem remanufactured battery, that still works great after 5 years at half the cost, hmm. well i think you should do the math your self. in the short term, i have no doubt the lithium battery is far superior. however for the long term, the oem battery will remain consistent for many more years i think over this battery, say after 5 years, in which case the oem battery would be a better value. i mean you wont know if you dont math it out your self, compare duty cycles of both types of batteries, and over a 5 year period, examine the true savings and costs of each battery.
These original LiFePo batteries are showing almost no degradation after 7 years of constant use. The tech is incredibly promising which is why Toyota is looking into using it.
What you think about getting rid of the catalytic converters with your more advanced battery, that way Prius owner don’t have to keep looking over their shoulders about getting them stolen!
Extreme cold temps can damage the battery however not many people have a Prius in the sub zero temps and if that is the case you would want to wrap the NiMH battery or the LiFePo battery in a thermal blanket anyway to keep it from getting damage. Both batteries are susceptible to damage in cold temps.
Having seen these on another video drive 5 miles / 8km on EV-only this is tempting to swap out even though I don't need to. It's annoying when the ICE kicks in all the time with the weak NiMH batteries....
Quick question; the NiMH BMS doesn’t have any battery balancing; the voltage sense harness only measures voltages. It works because NiMH charging efficiency falls at higher state of charge, and wastes charge as heat - meaning the car ‘overcharges’ the battery slightly if there is an imbalance. NiMH can tolerate this slow overcharging. How do the Lithium replacement cells manage this (especially as they can’t communicate with each other)?
@@backwoodsbungalow9674 I'm not certain, though reads like each battery has their own BMS-Charge Controller-Under/Over Voltage protection? Is that correct?
If somebody reading this/watching this has replaced the batteries with these BETTER units, have you seen increased performance? I'm talking better acceleration, 0-60mph, etc. I have still to read feedback with objective performance numbers. Thank you!
Hi! So performance increase is a yes. But not in the way you think. Your battery can hold a higher load over a longer period of time. That means as you accelerate the battery will continue to provide stable power out put. Your passing and climbing loads are also more stable as the battery doesn’t drop off like NiMH does (and especially on an older or reconditioned battery) Your Prius will feel stronger and quicker. But by how much? I’ll need to make a video for that.
Hi, Would it be possible to get the 3D printing STL files for the empty case of these NiMH packs? Or just buy the empty cases and fit the batteries ourself?
@@monoshock57, basically they are replacing the "blocks" in your existing pack. Think of this as like 14 blocks which is how the Prius BSM reads the system anyway.
@@TheHybridGuy if i bought a 3500 $ battery i would want to watch to make sure it isn't swapped with a cheap one (for my tahoe) if I was to take it to a shop
Any plans to get more in stock... wow... I just looked a few days ago and there were at least some cells left. They're all sold out now! Man! Guessing they're lasting well too or people just want those cells for whatever they're doing. ;-) Let us know what your thought are when they'll be available again? Great to see a like for like, like cell swap.
Hi there , is shipping to New Zealand an option? , shame @$1900 thats over half the cost of another car.and i bet shipping outside the USA would be anothe $300 USD😞
No reason to buy this Lithium battery, because those NMH battery's can hold for ever. Mine is over eleven years old and still fine ! Furthermore NMH is much better in cold driving conditions as those new Lithium battery's .
Actually these batteries have been in testing for 10 years now. They show improved fuel economy, performance and have no issues with heat, cold or humidity. Did I also mention that they do not leak electrolyte, or vent off toxic fumes? These batteries ROCK! Better ingredients, better batteries, choose Nexpower.
Lithium runs MUCH cooler so the venting needs not modification. These batteries are made specifically for the Toyota hybrids right now. projectlithium.com/?ref=e9JRo
The Prius plug-in has a better battery. The PHEV cars from Toyota use Li-Ion which allows them to draw the current required to run EV only acceleration up to higher speeds.
If I use lithium battery of chr and use it in prius 3rd gen, will this work? Mind it that I'm from Karachi, Pakistan where its impossible to get your services. We have to get a used Japanese battery part only.
One thing ive noticed.. the SOC is usually 60 to 65%...so it goes bad faster as its not fully charged and utilized. after lithium changeover what will be the SOC? if its still 60-65% wudnt it be under used again.. and may eventually go bad soon😕
Excellent observation. With these packs, because they are internally regulated with their own computer chip they are allowed to charge up to 97% instead of the 70% that you see with NiMH. Over years of use they will go bad but so will NiMH. In that time frame you will get longer sustained and better MPG than you would with NiMH.
I believe that the EV industry is going to explode. After studying the batteries, The batteries EV’s come with are so behind in the times and I’m not sure why the technology is not being improved around the world by more companies. I want to get in on this technology now. I am thankful to find your channel.
@@TheHybridGuy Ty for your reply. $2,300 vs green tech auto $1,900 installed. How long should I expect lithium battery to last? I'm not looking for the cheapest I'm looking for the best choice. Want what is going to last longer.
@@GEAUXFRUGAL green tech uses old used modules in their packs. The energy density isn’t as good as the LiFePo packs. NiMH is a solid bit of tech but LiFePo will does just as good and the modules you are buying are 100% new not used.
@@TheHybridGuy If price were comparable and last as long it's worth it. I don't need a hybrid I get out this time it's for good. Just don't drive that much.
I hope we can get a video of this thing in action. I'm getting about 39-40 MPG @ 185K miles currently on my 2015, so I think it's time for a new battery. Will this pack get me back to the 50's. I remember getting 56 MPG back when I first got my Prius with 66K miles. Thanks!
