This is the BMS v2.5 from Li-Ping, which came with my LifePO4 battery pack (10Ah, 24 cells, 12s2p layout, each prismatic pouch cell is 3.2v 5Ah).

This BMS is rated for 40A maximum continuous discharge current. It features the usual protection against over charge and discharge, etc. More importantly, this BMS automatically balances the cells during the charge phase.
I have the original pouch cells, but unfortunately 4 of them (2 pairs) "died" (low voltage).
I salvaged the good cells and rebuilt a 5Ah battery pack (half the original capacity, 12 cells), to test the BMS.
I therefore have 8 cells spare, all with good voltage.
Plenty of life left in these LiFePO4 cells (barely used, low number of charge cycles).
Safe chemistry, and great discharge rate.
I have the original 36V charger which was sold with the battery.
All of this is now surplus to requirement, as I use a smaller 2.5Ah battery pack for my short e-bike rides.
I am selling the BMS on its own elsewhere for £20, but since it is now soldered on the 12S1P test pack, I would rather sell the entire DIY battery kit.
I am asking for £98 (cash on collection, East Sussex / Kent).
This is for the 36V charger, BMS, and 20 good cells (12 of which are currently configured as a 5Ah pack, which shows the BMS working)
