How long will it take to charge a LiFePO4 battery?
The length of time it takes to charge a li-ion deep cycle battery depends on the type and size of your charging source. Typically, you can only charge lead acid batteries below 20% of their actual capacity, this is not true with li-ion. You can charge a Battle Born battery up to 5 times faster, although we only recommend that you charge at 50% of the capacity to extend the life of your battery. Keep in mind that you can charge a 100% the capacity of the battery, this will shorten the cycle life (our measurements indicate this would result in 2000 cycles with 80% capacity remaining) but the battery and the BMS can handle it.
