48v 16s3p A123 26650 Lifepo4 Module 52.8v 7.5ah 396wh
It's very rare to find 16s Lifepo4 48v modules like this. They are very clean and made of A123 ANR26650M1B cells. There are a total of 48 cells in 16s3p configuration. All you need is a T-15 security bit that is at least 2" long to open the case. There are 14 screws. The case comes off easy, no glue at all. There are 2 separate 8s3p 24v packs inside so you could also easily make 24v modules out of these. The busbars are copper and the cell holders are really nice too.
At this price it comes out to just $1.25/cell plus you get all the holders, wire, enclosure, and copper busbars.
We opened up every module and checked to make sure the batteries are balanced. We guarantee the module will be reasonably balanced when you receive it. They were removed in working condition and don't appear to be heavily used.
Note: The BMS is likely proprietary. You have easy access to the balance leads to add your own BMS. We have 30a 16s Lifepo4 BMS units for cheap. They would be perfect. Maybe you can find a way to activate the BMS but we do not guarantee the included BMS will work. The BMS likely only activates when connected to the device it was made for.
Module weight is 10 lbs.
Dimensions are 11.5" x 8.75" x 3"
Specs for the M1B cells are in the 2nd photo. They are power cells and likely the best 26650 Lifepo4 power cell on the market. They can handle 50a continuous per cell and up to 120a for a 10 second pulse. The copper that is spot welded can handle a lot of current but we are not certain on the limits.
The cells will say LithiumWerks on them. They are the same model and cell as the A123 cells. LithiumWerks makes high quality battery packs and this pack in particular we can say is built exceptionally well. They did not cut any corners or use cheap parts. You will also be able to recover some copper bar and shielded copper wires.
