72 volts.
The terminating charge voltage of the lithium iron phosphate battery is 60 times 1.2 equal to 72 volts, so the 60 volt lithium iron phosphate is fully charged at 72 volts. Lithium iron phosphate batteries are resistant to overcharging and have a low cost. The batteries have high temperature resistance, the thermal runaway temperature can reach 800 degrees, and they have good safety performance.
