Any feedback or recommendations towards something different?

That charger can work, but it'll take most of a day to charge your pack at 4 Amps!

I chose to use one of these chargers, and since it's 15 Amps, it'll fully charge in 4 hours or less. It can reach 59.3 Volts maximum before shuttng off, so you'll need to wire it so the BMS controls it, similar to the way I did it.

The BMS I used, if wired direct to the chargers C- lead (and the load), can handle up to a 60 Amp charger and a 120 Amp load. I intend to draw more than 120 Amp peak impulse loads. That is why I'm using a relay to control the chargers AC power input, and an interlock in series with battery power to the keyswitch. I could have used a much lower powered BMS. I chose what I found that met my settings requirements. 52V nominal and 58.8V maximum cutoff, and a 14S cell stack BMS input.
