More information:
Each module is rated for 72V and 58.8Ah. These are brand new modules that were never used in any application. A rare opportunity to get New A123 modules for a very low price.
You can make a higher voltage battery, these modules are rated up to 400V. You can also parallel these modules together for more capacity.
We have some data on the CAN communication we can share if you request it, but we are not sure if it is the same for these modules. Please email energy@greentecauto.com for this data.
Each module has a BMS attached to it, there is an off the shelf MCU that works with the built in BMS that can be found here. If you plan on installing your own BMS, it will be quite easy to access the BMS wiring once you take the top and side covers off. You can cut and splice one wire at a time from the plug that leads to the BMS.
Shipping will need to be freight due to the module size. We can ship this module to one of our locations for no more than $250, or ship to a commercial address or freight hub near you for $350. Residential freight delivery is possible for an additional charge, contact us for a quote.

Very surprised by the construction and quality of these batteries. Time will tell how they hold up in application but they seem very well made. I got the MCU BMS to speak via can bus to the batteries and had great service experience from my local GreenTec Auto location in the Chicago area. Great stuff so far.

Batteries arrived very well packed and undamaged. I have not had time to dig into the built in BMS to see if I can make some kind of converter to make it talk to my system, but I hit the batteries with a voltmeter and I was happy.

I purchased one of these batteries to see if it would work as a golf cart battery. By the time it was delivered and I was able to take it apart and inspect it, they were all sold out. That’s because these batteries are brand new and at a very affordable price. After taking it apart here’s what I found out. All cells are laser welded together and each cell has a balance lead already connected to it. It is very easy to install your own BMS system, just follow each wire back to its cell. The only down side is because the cells are laser welded and not bolted together it would be hard to take it all apart for a custom battery pack. But if you need a 12s or 24s or 26s or anything of those combinations, you’re set.
