TESTED 12s Lithium Ion Battery Module 44v 31.75ah 1388.30wh - shelf J1
Here is a 12s Lithium Ion battery module that came out of a stationary storage system. The battery is fully tested and you can see the test results in the 2nd photo. That test result is the exact test we did on this particular module with our professional testing equipment. So you are getting exactly what you are paying for. This module comes with a ribbon cable that you can stick pins in for your balance leads for a bms. There is a battery management unit that communicated to a main computer so the bms on the battery can't be used but you can use the male connector on the board to use for your balance connector. The main positive and negative posts are sticking up on the top of the battery as you can see in the photos. With the right size screw or bolt you can definitely thread it into the post. The post is not threaded but it is hollow and will thread with the right size bolt so you can add a ring terminal to this for your main connection.
Weight is 32 lbs.
I'm not sure what the module was when new but the cells appear to be 34ah cells so it is likely that this module still has 93% life left.
Dimensions are 7" x 12" x 8"
