Power cable too short

[sparkysxx]

Hi,

Stupidly I cut the power cable coming off the BBS02B, its 6 inches long now, I know I shouldn't of cut it but its done now, so all I can do is try my best to fix it, can I simply re solder it back together and use heat shrink with adhesive lining to make it longer again? I'm good with a soldering iron, i've spent the last 20 years tinkering with old R/C cars.

thanks

Yes, but you could just fit a hi power connector too like a waterproof marine grade xt90?
an extra power isolation option might be a nice security feature against opportunists.

I was thinking of just wiring the controller straight into the battery with no connector involved at all, wish i had thought of that before cutting it but there ya go, I can't uncut it now. I was just trying to make it neat, but theres a load of other long wires that I can't cut anyway so don't really know why I did it.

I have the capacity to make the cable coming from the battery as long as i want it to. Its a shame that the power cable is potted in the controller, otherwise I'd just resolder it there.

Also i doubt this bike will see any water unless it starts raining whilst I'm out and I plan for that not to happen.

Re attached it but feel like a knob for cutting it in the first place, this hasn't helped y OCD, also lost more length on the cable doing this as the heat shrink was shrinking as I was soldering so had to start again.

I'd add an extra layer of protection using self-amalgamating tape. Underneath it will get a hard life.

Bit late to the party. I soldered the ontroller wires to the battery, with branches off for soldered on lights - covered with self-adhesive marine heatshrink plus self-amgamating rubber tape... because marine heat-shrink has a hot glue layer, which of course can loosen and break down with movement, heat, oil, chemicals, sunlight, cow flatulence, cosmic rays etc.

Looks good. How is it held on? Are those drainage holes at the bottom? So long as this object doesn't lead to your soldered connections to be immersed in water causing a short. The sheathing of BBS01B controller wires is pretty tough, but ostensibly for a modicum of impact protection, I surrounded them with webbing stuff used to organise wires in PCs, secured with the particularly small zipties often supplied with that webbing. Three or so years later polypropylene webbing and those wires are fine, but the controller has been somewhat eroded.





Weird because I hardly ever go offroad. The motor casing is fine, it's paint must be sterner. 30ml of this "Heat Resistant" gloss paint arrived the other day, will get around to giving the controller a lick of paint, using the convenient in-cap brush. It'll take many years for toxic flatulence emitted by a multitude of creatures (you know who you are. Please desist), road debris and cosmic rays to erode or dissolve the controller case, it aint thin aluminium.

3d print worked out well but need to shave a bit off to fit my frame, will update with pics soon, worked out how it fits aswell, clever design
