Switching between different cell batteries

Im currently running 6s2p and was going to upgrade to 8s2p for a lot more torque on my 280kv sk3. Id need to limit the erpm since thatd give me too much speed, but if I was to switch between battery packs would I need to adjust vesc settings?

upgrading from 6s to 12s would yield a substantial increase in torque. upgrading from 6s to 8s is probably not gonna make much difference in torque.

You can however increase torque by increasing motor max current. I found that when I increased my motor max from 60a to 80a that it increased my torque noticeably.

Basically the Cutoff voltage. Just monitor your battery.
