Hello guys,
Due to a video on youtube i got my hands on an 10S 60A Li ion Smart BMS from Bmsbattery.com. Here is the link https://bmsbattery.com/bmspcm/833-16914-smart-bms-10s13s-60a-with-blue-tooth-android-or-ios-app.html#/17-battery_type-lithium_ion/107-cells_in_series-10 . In the beginning everthing seemed so work great. I connected the wires as shown in the diagram on the website und pluged in a 600W CC CV Buck converter with the voltage set to 42 V. The charging began and no problems occured only when i set the current to 2,3 amps the converter startet to smoke a tiny bit. After the charging was done i made a little tour with my board and after that i tried to charge the board again but with no success. I honestly have no idea what could be the problem. Has someone an idea ? I am afraid the bms is broken but it still balance discharges and shows no error in the bluetooth app

i would have a look on the component which started to smoke.
I’ll post some pics
The Capacitor i think smoked a bit but the Voltage output is correct.
This is a screenshot from the app. So i think it cant be the wireing because every cell is detected.
The cap smoked? Weird stuff
Are you sure the charger plug which goes to the bms is okey? I should measure the charge port of the bms if the voltage is correct (around 38V).
If that’s the case I don’t think your bms is broke but I guess your charger has failed.
Thx for the reply the BMS shows 38V on the output. Maybe it’s really the charger. I’ll order a new one and post results.
A couple builds back I had the same issue with a power supply and a step u converter which didn’t work, no idea why but the problem was also the charger.
I got my 42V 4A charger from alliexpress (25€) and it works good for me.
nice a new charger is on the way
So everything works fine now it was indeed the faulty charger thx all
