Charging a lipo battery charger has always been problematic at best. Expecially the earlier ones. They do not tolerate being discharged deeply.
Yes some batteries do have built-in protections. But no battery charger will output that current. Generally, batteries are charged at a 1/10 C rate. There are higher rate chargers but protections must be maintained.

For example a battery with a capacity of 1000 amp hours will only be charged at 10 amps safely no matter the composition of the battery. High rate charging circuits must take into account the delta Voltage vs current as well as the temperature of the battery and the battery condition. Which can deteriorate to the point, the charger must fault out before frying the few remaining good cells and possibly causing an explosive battery.

Way to many failures on this end with LIPO batteries. I do like their high discharge rate. But you have to know when to stop otherwise the battery will be damaged by over discharging it. Then try to charge it and it swells and becomes junk in one cycle.

Stick with other technology unless you have an absolute need for LIPO.
