48 volt server battery available from Battery Hookup. This video is kinda long because I start with tearing the battery down. Then re-building it with a new BMS from Daly. Charging to 4.2 volts per cell. Then I do a capacity test at about a 0.2C rate. Finally I use the battery in a real-world test. Guess what, I can weld with it! Wow.
The battery is originally made for server racks. It is capable of 100 amps discharge! Huge for such a small package. The steel case and insulating liner makes this a very safe enclosure.
Battery Hookup is going to sell the battery and BMS used in this video. Use coupon code "davidpoz" for 10% off.
Home Page: www.batteryhookup.com/?rfsn=3...
I think this battery is better suited to smaller projects. Maybe an electric go-cart, E-bike, portable power station, etc. Yes, it can also be used in powerwalls.

Nice job welding those pallets together David. I've never seen that done before. You put my old high school welding shop teacher to shame with your mad wood welding skills. Lol Keep up the great videos And the great projects. Wondering if they even teach welding or wood shop in any schools anywhere these days. Turn 55 tomorrow and I have to say it's nice to see younger people with good practical skill sets and an eager to learn nature, and then using those qualities to teach and help others just for the sake of sharing knowledge and helping people to attain real independance. Thanks David- I could not have successfully built my system without the RU-vid solar community to learn from. You and probably 4 other sol brothers are in large part responsible for my achievement of living fully off grid with two rental units and our home. You are a fine example and a truly generous person to share your life and experience with us all. For the record I am hereby claiming the term "sol-brother" as my own intellectual property !

@fcbrants 4 года назад

If anybody gets one of these batteries, try to power it up, then jack it into your network (with DHCP active) & check to see if a new device shows up on your network. I’ll bet the BMS had enough intelligence to get on the network & it’s possible (just guessing, based on my experience with commercial APC UPS’s) that it has a web interface that will allow full control. You might even find a MAC address on there somewhere...

Instead of the BMS needing some proprietary signal it might have just shut off because of the low battery voltage. Would be worth checking the system with normally charged batteries. If the BMS would need some proprietary signal, this might be available by HP. It would be a great benefit: even more power at lower cost and less hassle.

@bobm7275 4 года назад

One should try, seems like a massive amount of work if it could be used as it came. If they are selling them, it would pay to find how to use plug and play so to speak.

@christopherleubner6633 4 года назад

These are designed to give breathing room if the main power supply fails to ensure the server can shut down safely. It will have a monitor that turns it on if the power drops below 45v, and off at 48v. Will have an ok output and and an alarm output signal. Will have a 5v input that enables charging by external control to prevent the pack from drawing too much power too quick.

Yes seems like a huge waste of time and money, worth trying to use as is to plug and play.

The Daly BMS is really good at keeping the pack in balance. I have one on a 36V pack and after 6 months abuse I took the pack apart and all the parallel cell groups were perfectly balanced. The only Issue with it is you cannot monitor them live once the battery is sealed up. You need something like an ANT BMS along with the VBMS App to do that.

@felaxchow207 4 года назад

Definitely a cool repurposing build. I'm glad you put in a circuit breaker in line before the Anderson SB50 connector, if you need to take one offline in a multiple power pack configuration on a bus. The SB connectors are not rated to be disconnected under load and you'll have a very interesting arc show (don't ask how I know). Anyone who has multiple voltages running amongst the work shop, I followed the defacto suggested Anderson Power color code on the SB connectors as follows: Yellow = 12 volts nominal Red = 24 volts nominal Grey = 36 volts nominal Blue = 48 volts nominal Green = 72 volts nominal The nice thing is that they will only mate with its color and amperage group so you can't connect a blue SB50 with a yellow SB50. It has save me some unintended letting out of the pre-installed smoke from my equipment. Plus, I use the Anderson Powerpole 15/30/45 for my 12 volt Amateur radio equipment and appliances up to 45 amps. They're a bit pricy, but the connectors are genderless and saves me from having female/male connectors all over the place.

@DavidPozEnergy 4 года назад

I did not know there is a color code. Does that mean I should be using blue color? The Amazon page where I bought them says 600v.

@felaxchow207 4 года назад

@@DavidPozEnergy It is kinda a yes and no. If you are using the SB series and have equipment running at different voltages (i.e. chargers, batteries, widgets, etc.), they suggest using the color coded shells that Anderson Power Products in that format to prevent accidental connection with the wrong equipment rated voltage. It is not mandatory that you do it that way. If you decide to go with that format, all you need to do is purchase the connector shell of that color and switch it out. If you don't have any plans to have different battery pack voltages floating around using SB50 connectors, then what you have is fine. In my case, I have 12, 24, 36, and 48 volt equipment and battery packs on the SB50 platform. I just went with their suggested color coding for safety reasons. Wikipedia has a better explanation on this subject en.wikipedia.org/wiki/Anderson_Powerpole

@therealchayd 4 года назад

Rambly explanation warning: That massive BMS board is probably a computer in its own right for monitoring the pack state from outside using a protocol called SNMP over ethernet. The idea being that you can manage the battery pack remotely, check charge/discharge state, pack temperatures etc. Probably not needed for non-server use. Most servers also have a management controllers on so they can be powered on or off, rebooted, check fans, temperatures and all that stuff. This technology has saved me on several occasions from having to make a hour round trip into work at midnight just to press a power button.

Yes, server racks will hold a UPS. The rack mounted UPS is designed for it.

great video and nice build. esp that you can fit the BMS and circuit breaker neatly in the original housing. Out of curiosity, did you consider just use the whole module as a whole , since all key modules are there including fuse/BMS etc. Given it's for server rack, i suppose it's heat dissipation and safety features and BMS functions are all pretty good. it's just a matter of reading and pulling out data ....could be extremely difficult without knowing original part number and the software talking to it. but if in case you do find it out, it's going to be super cool

Yes, you can parallel as many as you want. But when you parallel packs try to keep the wires the same length from your central point (Buss bar). You don't want a pack close to the inverter to get hit with all the amps.

If I were to buy a few of these, how would I get them started without making all the changes that you did?

Can you show what you're going to do with it? I don't know much about batteries...but want to learn

As long as the cells gave voltage you can revive them, charge on a low current high voltage charger till you get about 3.3v per cell. Let sit and measure, if it holds charge away.
