For daily charging, I charge to 4.14V-4.15V per cell. That comes to 82.8V-83V for 20S. I noticed that some lead acid battery chargers charge to 82.8V. They do constant current>constant voltage>floating. I assume that the latter means that if the resting voltage drops below 82.8V, the charger would kick back on/off until it settles at an 82.8V resting voltage, but that's just a guess.
What would be the concerns with using this "lead acid" charger on a 20S lithium ion pack? This one is smaller than my current charger, so could fit in my rack bag, and I wouldn't need to open it up to adjust it, like with a 20S charger.
