DollaTek battery BMS Board Module Li-Ion Li-Polymer battery pack protection board BMS for 13S 48V / 54.6V batteries

I dont know if this is a good or a bad review but yeah it didn't work for very long at all. So I wired it up worked fine the first day a week later it wouldn't accept the charge and was outputting 24volts instead of 48v .

Bms ebike battery 🔋

Seem to be working alright. No issues at all. Done 4 charges so far. I think is good value basic bms

This bms is supposed to charge cells up to 4.2v but instead its charged them up to 3.6v and cuts off definitely waste of money and time wouldn't recommend someone to buy this

Didn't work from the box, useless waste of money

It helped saving a good working lithium battery

I bought it to build a supplamentary 13s2p juice to my ebike but it seams that it was a wrong buy. this does not have battery balancing function. Does not worth risking the batteries.

Bms seemed too good to be true but to my surprise after hooking all up, it worked great! * 2 months later it died out of nowhere.. Checked cell levels and almost every cell group was out, some being 15% off which BMS should have cut it off way before that but failed to do so. Manually balanced all cells and attempted to hook up the BMS again but it done ... What a shame man, I feel like 90% of electronics specifically only last! Couple months, long enough to get them through replacement period 😕
