DALY Smart BMS with Bluetooth Wireless Control SOC UART 10S 36V 40A 3.7V Li-ion Battery Protection Board with Balance Leads Wires BMS for 18650 Battery Pack(Smart BMS,40A)

My Li-ion cells were wildly out of balance with each other. The stock BMS that Gotrax uses on the battery pack was a JETECH-9210-I-V2 that smelled nasty. I wired in this nice new DALY BMS and put the battery on charge overnight. In the morning each of the 10 series strings was a nice 4.17 +/- which is amazing on this 2018 battery pack. My cells do have high Internal Resistance (IR) but each 2P string has about 4600mAh, so my scooter does not zip the way it used to when new. I have 20 new INR Li-ion cells with 2600mAh at ~30mOhms I.R. so I will refurbish this pack now. I am so impressed with the DALY BMS!

This is my second purchase for my scooter easy install gear deal

built a samsung 2p 10s battery and mowed the whole yard with it

My wifes account.... Daly BMS was shipped fast and got here in Canada days before it was supposed to, like a week before, however the box was a bit crunched, ok more than a bit, flat like pancake, so maybe they could package it a bit more like how Sabvoton packages their controllers... IE: foam packed in another box using these for ebike motors, sabvoton controllers, 21700 5,000 mah 14.5A constant 20A surge, 11s10p 52 ish amp hour, yes I could have used a 150A but with 4 battery packs the same @ 100 amp each.... dont really need it :) gotta love Battery hook up . com

It's a great Bms from Daly, made to last and plenty of info and data you can play with. You will not regret buying one of this. Keep up the Great work Daly

Always have had good experience with these brand of bms's with all the battery builds I've done

Using on my homebuilt ebike battery packs and seem to work perfect for me. I'll be getting a few more..
