I m curious n like to learn from failure. I m curious and like to learn from failures. Tough the corrosion you mentioned in c12, this charger is still energized; just it is jumping to higher voltage output 68v instead of its rated voltage of 54.6 vdc. It's like a resistance failure here. The...

Agree with yah. I think, also rising questions to an expert for the purpose to learn and understand something from those failed circuits...

Hi every body in the forum. I did shorted my "54.6"vdc charger "." It still working but passes its rating voltage now, it become higher of about "68vdc." I dont know how to reduce it. Any help gays? I will appreciate it.

This happens after i soldered the wireless BMS back on. As soon I turn the lcd on, the power cut off and the battery "Empty ICON" continue flushing, everything else works fine on the lcd. The charger has normal 54.6 out put, the controller behave normal after check. The cell blocks test 3.5 to...

Thanks again Harry for the tips. I disconnected completely the wireless bms (away from circuit) n placed the old s14 bms (after i shorted #12 n13 harness connectors together to convert it to s13 BMS?) it looks working, I tested each cell from the harness to C- or P-,the meter shows equal...

How r u doing gays? I still have BMS echo. My bike battery is 48v, kind of hailong with a Wireless 13s BMS soldered on the top of the battery. The discharge wire terminals give only half voltage about 27v instead of total 48v, but the test of each cell block gives right and equal 3.7v, and its...

Thanks, Harry for the tip (LCD was not connected to close the circuit.)

Sorry for back to u late , I m "dum" i should look at circuit diagram to close circuit (sw on-off or LCD) , finaley i did n it works and powered the system. thank you gays.

before I mounted the motor, battery ....I tested on the ground all those controller output cables for 5v and so on, no power at all .

I got an Ebke kit of 1000w motor, 48v battery and a 48v controller. everything went smooth except, the controller wont power on when i connected it the 55v charged battery, as i know after search, this controller can handle ~56v to 60v. I opened it, after multimeter test all 12 mosfets showed...

Hi everybody. after connected to a 55v battery charge, to motor... the 48v controller wont power, after check, nothing burned out inside, this controller can handal to ~56v+. any tech assistance? I will appreciat that
