We are running a PD4655L Wildkat converter set to the li setting.
It charges at a constant 14.6V until our single 100AH BattleBorn battery reaches 100% SOC. It starts out pushing 55 amps and then tapers off as the SOC gets higher, once the battery reaches 100% SOC the amperage tapers of to almost zero (usually around 0.25A or so).
I let it sit disconnected from the converter somewhere around 70-80% SOC and then charge it before we leave for the next trip, it charges so fast that it's no issue at all.
