I had my concerns for a while, and today they was realized; enough water had seeped into my battery pack (on the bms side) during a short period of rain that the bms cut the power.

Normally, my bike are parked under a roof, but I was down in the harbour this afternoon to help a friend with his boat motor (that had been under water...

). During my go at being a mechanic, there was a half'n hour of rain. When I was ready to go home, the bike was totally dead. Fortunately, my friend had his car with a trailer with him, so I was saved from an
unmotorized bikeride home.

Well at home, I measured the outlet of the battery, and there was 0 Volts. I opened the bms end of the battery, and there was several droplets of water on the circuit board, and it was damp inside the plastic end. (BTW: the charger plug was also in the process of getting loose...)
As soon as I dried the water off and blew a bit to get the rest of the water off between some of the component legs, there was 39 Volts at the outlet...

I've been thinking of sealing the battery ends, and drill some draining holes at the bottom ends, but a thought struck me; a simple water resistant cover over the top of the battery would be better than sealing the battery.

But i'm going to drill the draining holes anyway, so that any condens water has a way out...
And yes, I
did get my friend's motor to run...
