Would a LiPo battery need protecting from reverse current? (programming.dev)

Im working on a board for controlling a few linear actuators. They will at full load draw something like 10A, and will be powered by a 24V (or so) LiPo pack.

I have a few H-bridges and as expected when the power is cut off, there is an inductive kickback of about 10A. No PWM, they will be turned on and off occasionally only.

I havent been able to fibd anything on if a LiPo pack would be able to take this reverse current, or if it needs some sort of protection. It also lasts for quite a short time but I'm new to batteries so I want to be sure its not a problem.

Would apprecaite any help :)

If they’re on for a short time, you’d be fine with a schottky diode
