How to read individual cell voltage on lipo4 battery without Bluetooth?

[RPG]

Is it possible? Is there an app or device that I can purchase that would allow me to see the individual cell voltages? I’m running 4 200ah Redodo’s, they don’t have Bluetooth.
thanks for any assistance

If they don't have Bluetooth, I think all you can do is crack the case.

Hard to say what BMS Redodo are using, though based on the one or two teardown videos I could find, I'd say it doesn't provide any kind of external communications. You'd probably need to open the battery and replace the BMS with a more capable model.

Thanks, I think you’re correct. Darn.
