I have a 9s2p battery and a 10s2p liion battery, both have BMS. I intend to use them interchangably with the 9s as a secondary battery when the 10s cuts off. However, the 10s bypasses the BMS for discharge as the BMS has a low 30A discharge. When using the 9s, battery voltage cutoff values on VESC tool are set to 0 since the BMS will cut off the battery when voltage gets too low. When using the 10s, I set the voltage cutoff to end around 33 volts. If I were to ride with my 10s battery until the VESC cuts it off, after swapping out to the 9s I would only be able to use the 9s until it’s nominal voltage.
I thought I could solve this by getting a flipsky nrf51 bluetooth module and the Xmatic iOS app to change the battery voltage cutoff while out on rides away from my PC, but after purchasing the app and connecting it to my VESC via the nrf51 module, I see that I am unable to modify the VESC’s cutoff voltage. The battery setting on the Xmatic app seems to be used to tell the board’s range and battery percentage. Although I do notice that there is an option to charge the battery to a certain voltage, I suspect that it is only used for battery percentage purposes. I do not have an andriod phone so vesc tool app on the play store is inaccessable to me.
tl;dr: Is there an iOS app that allows users to modify vesc settings such as battery voltage cutoff start and end?
