No, we didn’t. I’m still unsure on what was the main cause of the fire, but from the location of the ignition of the fire, the battery connecting were not the culprit, at least not the main cause.
The main possibility was a disconnection of a bullet connector in the splitter for the power of FocBoxes, that could be causing consecutive big sparks that ignited the flamable foam I use to protect the electronics from vibration.
Once the fire was ignited the heat could easily have melted the cells isolation rings causing a short between the positive and negative leads of each individual pack.
I making a point here as I would like people to think wrongly that the main cause were the wires.
So if you want an advice, don’t use bullet connectors, use XT60 or XT90 instead (they are protected even on dsconnections, if they unplug for any reason you won’t have a bare naked cable tangling around electronics and battery leads as the male bullet.
Another advice, don’t use this neoprene rubber sponge to avoid vibrations:
I use it on my Trampa and while it worked amazing they are flammable.
@pshaw yeah, but on my enclosure I had a Y splitter made out of bullet connectors for both VESCs and all they were heat wrapped, however if one got disconnected the male bullet woul be bare nude, so heat wrap is not useful in this case, do not trust bullet connectors, go XT60 instead.
If one plug got disconnected and and touched the connection back again a giant spark powered by 2 VESC dual capacitors would definitely start a fire, even more when the rubber sponge was used on the electronics compartment.
Not sure as I only ever ran street wheels. Fastest I ever cared to go was 35mph. Farthest I’ve gone was 20miles in a single charge but battery wasn’t completely depleted and I was booking it. I needed to get off after that long lol.
