Just some notes for yourself or the eventual purchaser:
The CA can be setup to automatically do that for you, by controlling the throttle if current got too high.
It can also be setup to stop the system at a specific voltage level (LVC low voltage cutoff), if your battery does not already have a BMS to do this for you (any battery from EM3EV should already have a BMS with LVC)
One thing to keep in mind about not fully charging the battery is that unless EM3EV installed a BMS that balances at the lower voltage level, rather than at the "full" voltage level, the only way to balance the pack is by fully charging the pack and leaving it on the charger for long enough to balance (which can take days for a badly-imbalanced pack). Unless something is wrong, like you start getting less range before cutoff than you used to, generally there's nothing to worry about. But if that does start happening, then before you do anything else, try just letting it fully charge and leaving on the charger for a significant time after it's done.

Sure it does--any electric motor system at all would allow it. You'd just need to use the SA (standalone) model instead of DP (Direct Plugin), if the controller of your system doesn't happen to have a CA-DP plug already installed, and you don't want to add one.Patches1958 said:I also installed a "lemon hobby" watt meter because the Bafang system doesn't allow the use of the Cycle Analyst.
Paul said that I needed to be sure to keep my sustained current under 20 amps.
