Used Relion RB10-PC 12.8v 10ah Lifepo4 Battery

These packs are made of 16 cells. Each cell is a 26650 size and 3.2v 2300mah. They are in 4s4p configuration. Therefore, new these are 12.8v 9.2ah. Every battery has good voltage and was recovered from medical applications.

These are awesome little batteries and perfect for battery powered toys, backup lighting, and small solar systems. The larger bolts on the ends are included. Some batteries will need the smaller M4 x 0.7 bolts on the top. You can charge and discharge from the 2 smaller + and - posts on the top of the battery. Stay at or below 10a charge and discharge using those posts. Note: the large positive and negative terminals go right to the battery, not through a BMS. You can discharge up to 50a continuous on those posts. You can also have a setup where you charge on the top smaller posts through the BMS then discharge on the larger posts. If you discharge on the larger posts make sure you have some type of low voltage cutoff and a fuse, otherwise just charge and discharge through the smaller terminals on the top if you want full BMS protection.

Specs are in the 2nd photo.

All batteries will have good voltage and cycle just fine.
