48v 6.4ah 307.84wh Lithium Ion 13s4p 52x 18650 Cells

These are absolute BEAST power modules with Panasonic cells inside. 48.1v 6.4ah 307.84wh. Built for power but at this price it makes sense for solar storage as well. These modules have 52 cells inside in 13s4p configuration. They are rated for 307.81wh and every module we tested has tested around that capacity. The test of the module is in the 3rd photo. Since these were used as backup only for servers they likely have never been cycled. The cells are power cells, Sanyo UR18650WX 1600mah cells manufactured by Panasonic which are 25a rated power cells. This module can push 100a and had a 150a in-line fuse on it (fuse not included). It is just built so well and it is also easy to work with. The circuit board has balancing but the board is not a BMS, it is a BMU which communicates to a main unit so you will have to add your own 13s BMS. The 2nd photo shows the easy BMS wiring schematic. The copper piece connecting B- to C- will already be removed for you. BL stands for balance leads. BL-
