Re: DIY 10S Li-Ion pack! Which cells do you recomend? & BMS?

https://www.fasttech.com/product/2399401-authentic-sanyo-ncr18650ga-3-6v-3500mah I read something about: maximum 10A continuous discharge, does that mean with 4P would be 40A? Isn't that a bit to low? Or am I confusing things? I also found this charger: https://bmsbattery.com/ebike-charger-ev-charg...

Re: High Amp Master Switch

I just leave my batteries connected, and disconnect the logic circuits with a cheap on/off switch. this means the caps are always charged, and there is a small power drain... but its so small that its almost identical to the batteries just sitting out. I not understand what you mean. A switch betwe...

And what's about 2 parallel BMS'? Is that possible, or no go?
Or do you have other BMS recomandations?

Just not sure if it gives me enough amps?:/
Is it possible to wire 2 BMS in parallel to increase amp output? Or aren't amps that high on 10s?

Re: 10S custom skate ESC: testers wanted!

They will work fine with different capacitors on each VESC. You may be able to link them with the canbus port too? I would need to test this to confirm. Thx you're da man! I read a lot about burned drv chips, and most of those people had connected their VESC's over canbus. I have no real knowledge ...

UART could cuase problems in this case?
If they have different capacitors, will they perform equal or slightly different?

Re: 10S custom skate ESC: testers wanted!

Is it possible to use 2 different versions of VESC together? I currently have the (4.09? version - from enertion with a red pcb) is that compatible with the newer 4.10? controlled over splited servo wires.
If yes: do I have to use same capacitors on both Vesc's?
