I use LiFePo cells from electronic vehicle for my hoverboard motors. The batteries are far from ideal state but they work yet. To avoid any catastrophic damage of cells I would like to measure the voltage and current going to the batteries during deceleration of motors.
Are there any variables which I can read from oDrive?
Currently I have 4.4Ohm brake resistor connected to oDrive. Is it more safe to use brake resistor even if the power coming form batteries? Or it is absolutely unnecessary?
What measures or calculations should I take into consideration in this situation
Thanks for the help in advance!
