The 72V 32Ah E-Moto Battery is a 72-volt LiFePO4 pack of 2,304 watt-hours with a 64-amp continuous rating, rated IP65 at 20 kilograms. It is the touring size in the 72-volt range.
Distance
2,304 watt-hours between charges
At 20 watt-hours a kilometre in mixed riding the pack covers about 115 kilometres. Held at highway speed where consumption reaches 30, it gives 75. A rider planning a day out counts on the lower figure and treats anything better as margin.
Charging On A Trip
Planning the stop
A 72-volt lithium charger at 20 amps refills a fully drawn pack in a little under two hours. A rider covering 200 kilometres plans one meal-length stop rather than a wait. Charging from a domestic socket at 10 amps doubles the time and suits an overnight stop.
Weight And Balance
Twenty kilograms on the frame
A pack this size sits low in the frame on a typical machine, and its mass helps rather than hurts the handling once it is mounted at or below the swingarm pivot line. Check that the mounting takes the load in shear rather than hanging it off a bracket.
Balance
Why the cells stay level
Twenty-odd cells in series drift apart as they age. The board bleeds the high cells down at the top of each charge, and a pack that stays level delivers its full capacity for its whole life. A pack without balancing loses range early because one weak cell reaches the cutoff before the rest are empty.
