Hey Vlad! I bought a BMS from signalab (http://www.ebay.ca/itm/BMS-PCB-PCM-for-24V-25-2V-7S-Li-Ion-Li-Polymer-Battery-Pack-30A-60A-With-Balance-/152322936768?hash=item2377278fc0:g:2KAAAMXQ855RvpyC) and I wired everything correctly and it charged the batteries up to about 60%. Then it stopped working. Tried again multiple times (even started smoking) and rewired everything to the diagram (everything correct) and kept trying eventually the connector from the battery to bms (main) literally blew up in my face. Any ideas as to why?
