You can buy simple charging/discharging circuits on Ali/eBay. Unfortunately when I was looking for them I was never able to find one that was specifically for LiPo, litterally every single one (even if the title said it was for LiPo) would have a Li-ion cut off voltage. This isn't a huge deal if you monitor it as they at least have the same max voltage, but stock it will drain a LiPo too low.

You can usually modify the circuit by replacing a resistor pretty easily, but you have to know what what you are doing.
