We prefer the LIFePO4 battery chemistry because of it's superior power / cycles ratio... and greater safety than LI chemistry.
I'm just talking in theory.

You often see lithium batteries quoted in W/Hour rated instead of Ah as it allows a direct comparison of amount of stored energy. Even if you have a 6V and a 12V or 24V even a 72V battery, you still compare Watt hours DIRECTLY.
Its works like this. Ah x Volts = Watt hours.
So you can have;
24V x 100Ah battery = 2400watt hours (2.4 kW/h)
48V x 50Ah battery = same as above.
12V x 200Ah battery = same 2400 watt hours.
6V X 400Ah, still the same.
All the above are also the same weight, same volume, and contain the exact same amount of energy.
That's another way of looking at it.
I live and learn.
