10S 20a 36V LITHIUM ION BMS - FLAT STYLE

Here are 10s 36v 20a Lithium Ion BMS units that we salvaged from hoverboard batteries. Last year we broke down thousands of hoverboard batteries to test and reuse the cells. These are the BMS units. They are not tested but the vast majority should work just fine. You will just need to test them first, which is why they are only $2.50. If you buy 10 you will likely get 9-10 working bms units. We checked the mosfets on these and they are not burned out. At this price you can't go wrong, just make sure if you use these you monitor the overcharge to make sure the BMS kicks in first. You can solder your connections directly to the board. You can charge and discharge through the P- and P+ connection pads. These use soldering pads instead of JST wires. Under the green barley paper you can peel that back and the other 4 connections are there.
