Theoretical question for future. I have a 12s6p with a few hundred cycles of charge/discharge. I have a second 12s6p with no cycles done yet. How could I connect them together to allow me to use them both on one single board without having to interchange them during a ride? Simply connect the second one to the first? If so, how?
You can do it but the old cells will wear out much faster than normal, not very recommended
@ZachTetra Iām thinking ahead for next year. I want to add an underside enclosure to my trampa with another 12sXp (as many as I can fit in it) and overkill any range limits ever known to mankind
Edit: @eBoosted what is the max 12s pack with bms I could fit in a ds 35 enclosure? No esc, just batteries and bms
I mean you can do it, but youāll loose capacity on the old cells. If you want to do it I would say take the pack apart and make each p-pack have the same balance of internal resistances (each p-pack should behave identically)
Canāt do that. This pack is pcb welded
Alternatively you can use the new pack to charge the old pack, or just swap them with a breaker half way through riding
Yeah youād need to salvage them or weld the new and old p-packs together
Wouldnt, in my idea of configuration, the old and new 12s6p packs balance themselves out while draining?
I have a set of psychotillers heXl tkp trucks and motor mounts on the way. Will trampa 6.5 inch superstars work on them with the 8mm spacer bearings?
Hi guys! Iām very close to finished on my new board. I was programming my Flipsky Dual FSESC 4.20, perfectly fine. I set up FOC mode nicely and was testing the directions of each motor in the VESC tool, when all of a sudden, the first VESC (master) shuts off. I powercycled and checked my connections and I cannot get it back on. The error on the VESC tool says something along the lines of having matching firmware, when both were the sameā¦
Can anyone help? I hope I didnt fry my VESC at all.
Frick me, I was out riding today and this problem keeps happening, are my motor limits too high for my 12s2p? Iāll be accelerating and it pushes back almost throwing me off like a second cutoff, should I lower the motor amps or battery max? @kalebludlow @b264 help me!!!
Itās not that simple. You need some sort of current limiting circuit.
What are all your settings? Try lowering battery max
Iāll do that Tommarow morning, it probably has to do with battery max
Also give us all your settings too

Since I determined the shaft was not the issue and was the can, I just randomly thought of doing this to see what the can was doing and it looks like it is wobbling? Doesnāt look normal to me. The shaft is on there tight and is not moving whatsoever. So this is all the canās doing. I feel a tiny centripetal force when spinning it. Is the can just fucked?

If the shaft is straight, then the can is fucked.*
*depends on the skills and tools you have available to you. A machine shop could fix that, but itād likely be cheaper to just get a new can.
Basically either the back plate of the can is deformed, or the hole the shaft mates into is deformed, or the actual flux ring/magnet assembly is deformed. Iād guess one of the first two.

Iām planning on mounting the 2 x vesc 6 in my eboosted Urban Carver enclosure. What are the best options for keeping them cool? I was thinking of creating a few slits in the enclosure just beneath the heatsinks.
Any advice?
Well the shaft was ruled out, so it is that. Weird to me considering I only ever rode the board a total of like 500 ft, was can was fine when I stopped. Didnāt touch the board but come back to a fucked can. Must have been dark magic. Thanks wasnāt sure if it was fucked for sure.

Thereās always the chance that itās something else I havenāt thought of and Iām an idiot, but these motors are pretty simple mechanically - not much to hide.
Unfortunately with the way these motors are designed, theyāre fairly susceptible to that exact kind of damage due to the cantilevered can with no support on the other end. A really hard drop or impact might be enough to do it.
