Hey guys,
I have a 60v42ah batterypack. My bike has two 2800w engines and two 40A controllers. All is less then 6 months old, so more or less new.
The batterypack is a chinese 16s13p, I could choose how many Ah the pack had when I bought the bike.
I played around with different controllers a lot, and apparantly put it to the limits of the battery.
Engine started to loose power and I smell burning, plastic smell.
I stopped the engine the moment I smelled something, but I realised with this smell... There will be damage. One way or the other. No smoke though.
I walked home, opened up the battery case, terrible smell.. Hot.
I took out the battery and put it outside to cool down.
After maybe 45min I measured voltage, staight at the xt90 connectors of the pack: 62v. Normal!
Connected it to the engine to see what would happen: It has a external voltmeter, connected to the key ignition. The moment I switch the key I see the voltage going down very fast.. Till 32v. When switch the ignition off-on again, it goes up to 60v again, and then going down again..
The engines have not enough power to function.
No more burning smell, except for the smell still in the pack from before, quite smelly still and not a good sign.
The smell only seems to come from the front of the pack,
Where under the blue wrap, the BMS is situated.
What I did is ordering a new BMS.
The younger version of me would just connect the new BMS when it comes in(This week), and just see what happens..
Now I am a little older, 40+, with kids in my bought house, I just realised it might be better to do some examination, in stead of putting my head in the sand, acting like a cheap dutchman, assuming there is no further damage after that terrible plastic smell, and just connect it..
Could someone tell me.. With this symptoms... Do you supect the BMS?
I have to remove the blue plastic to remove the bms anyhow, should I measure voltage at the big white BMS connector?
