My Rolls 6V-820 Amp batteries are failing and I am looking for a substitute. One is Lifepo, but another is Lituium Titanium (LTO), which should be even more stable and long life than Lifepo. I can see it is possible to get them in packages with a BMS included. My thinking was 5 48V battery packages in series and simply use them as drop-in replacement for the FLA, of course adjusting the charging parameters in my Midnite Classic. Will that work? 8)
