These are 4-packs of 12v 5Ah LiFePO4 lithium iron phosphate A123 battery packs from UPS units. They were removed from working equipment with very low cycles.  LiFePO4 is great for harvesting cells due to their long cycle life. These A123 cells in particular are very popular among DIY because they are power cells capable of delivering up 70A. Each module contains x8 A123 ANR26650M1B cells in a 4s2p configuration. Each battery module also contains a BMS circuit.

Great for harvesting cells because they don't have glue and come apart easily.

They can be used to replace lead acid batteries in many applications. You can use this charger on small applications. If you do decide to harvest the cells you have to open and extract them, you'll have to cut and clean the Nickel interconnects using snips. Once the Cells are out and clean you will have to test them using a charger like this.
