12.8v 6.6ah 84wh Lifepo4 module with 40a BMS

Regular price $29.99 $0.00 Unit price per

Here are awesome little 12v 6.6a 84ah lifepo4 battery packs. You get a quality 40a Lifepo4 4s BMS and 8x 26650 3.2v 3300mah lifepo4 cells for just $29.99. These are used packs but still in great condition. We tested every pack and confirmed the cells are balanced so you are guaranteed to get a working pack. The cells seem to be a generic brand but these packs were made for a popular company so the cells should be decent quality. We also tested a few packs and they were between 80-100% capacity. The value of the BMS alone is worth the whole pack price, it is built very solid.

You will get wire leads as well so connecting these couldn't be any easier. Just parallel as many as you want to build a nice modular 12v battery. Make sure the packs are within 0.2v of each other before connecting them in parallel. 

Fully charged module - 14.6v
Fully discharged module - 10v
Recommended max continuous discharge - 10a (1.5c)
Recommended max continuous charge rate - 6.4a (1c)

Weight - 1.75 lbs.
Dimensions - 5.25" x 2.25" x 2.50"

The main wire included is 18 awg silicon wire which is rated at 10a. Most packs have 2-3 inches of wire lead so you can make an easy connection. Although there is a 40a bms on these units a good rule of thumb is 100w per pack. If you have a 300w 12v inverter then 3 packs in parallel will be perfect. If you want to pull more amps like 20a or so simply solder on another 18awg wire.
