20x 3.2v 1500mah Lifepo4 cell modules 30,000mah

These are awesome packs that make battery building a breeze. Each of these packs has 2x 1s10p 3.2v 15000mah modules inside and each module has the main positive and negative wires coming out. There are 20 3.2v 1500mah 18650 cells inside. To make a 12v 4s10p battery you can simply put 2 of these modules side by side, connect the 4 packs in series, and you are done! Or simply twist the 2 positive wires together and the 2 negative wires together on each pack to make that pack a 1s20p module that is 3.2v 30000mah. We tested a lot of these modules and they have all tested above 90% capacity so these were likely only used for backup or never used at all. They are super clean and we check the voltage of each pack to make sure you do not receive any bad cells.

If you make these packs into 1s20p 30000mah you can draw up to 20a continuous. If you use each 1s10p pack in series then each 1s10p pack can handle up to 10a continuous. Comes out to just $1 per cell but since these are built into packs already with wire leads the value is even greater. It is hard to find Lifepo4 modules like this for smaller projects that you can assemble in just seconds.

The wire leads are roughly 4" long so plenty of wire length even to parallel 2-3 packs side by side.

Module itself is roughly 2.5 lb. Dimensions are 7.25" wide, 1.75" deep, 2.75" tall.
