    charger voltage output max out

    You need a seperate bms for your lifepo4 and lipo, for charging you can charge it the same time just parallel them. The 87.6v output is actually for lifepo4. However you can also use that in lipo 21s it will be 4.17v per cell. Or increase your xharging voltage to 88v. Lifepo4 can handle up to 3.7v
