If the voltage isn't perfect though, we will need a BMS to cut charging when it's full.
I still have the charger from the old lifpo4 pack. It's charges to 60v. I have the sla charger that charges to 59v according to the label.
Alan B said:The lead batteries sag so much that a lithium pack with lower nominal voltage may outperform it.
52V nom is 14 of the 3.7V cells which is not a good number for lipo bricks nor for chargers. 6S is a more common, cost effective value for chargers and bricks.
44V nominal is a more practical value for lipo. You could use 6, 6, and 2S bricks to get 14 if it is really necessary but it will cost a bit more and require more wiring.
For 18650 packs with a BMS and bulk charger, the 14S is not as difficult. Some vendors call these 50V packs while others call them 52V packs, it depends on the manufacturer's cell ratings being 3.6V or 3.7V nominal.
I'm don't know what these 2s 6s 14s numbers refer to.
