I need to buy several battery chargers, new. I want to use them on various battery packs of various cell counts of LiPo ranging from 10 to 75 Ah. Nominal battery voltage for the charger needs to be adjustable from, ideally, 20 to 100 volts, but I may live with a more narrow range around 48V.

I would like to use either 110 or 230 V AC depending on available source. I want isolated chargers, preferably UL listed. And I would like them to have a BMS interface to turn them off. Charge rate is desired to take full advantage of the 110V/15A supply. Weather proof would be nice, but not required.

I have what I think is a suitable budget, but I can't go overboard, like for the $3K Brusas. Any suggestion or experience is appreciated.

Thanks,
