CHAPTER 6 BATTERY AND CHARGER
6.1 Batteries
This vehicle is equipped with a 76.8V lithium-ion phosphate battery and a 12V maintenance free
battery that supply the power needed to operate the vehicle. The batteries are located under the seat.
Always observe all battery safety warnings and safe handling procedures as outlined on vehicle
safety labels and in this manual. Refer to the battery maintenance section.
6.1.1 Battery Handling Precautions
Always make sure that all electrical accessories are grounded directly to the negative (-) post on
the terminal board. Never use the chassis or body as a ground connection.
Always keep battery terminals and connections clean and free of corrosion at all times.
In case of long-term storage, the battery shall be charged to the meter to display three or four
grids of electricity, with a maximum of 83%
Make sure new batteries are fully charged before using.
Charge the battery in time after a whole day's use, otherwise the battery capacity will be
damaged.
Make sure vent caps are installed properly and securely during vehicle operation and battery
charging.
Recharge batteries fully at the end of each day the vehicle is operated, allowing adequate time
for the charger to complete its charge cycle.
Avoid charging at temperatures above 120° F (49° C) ambient air temperature. Closed, unvented
storage buildings often exceed this temperature when exposed to direct sunlight.
Never connect any accessory directly to the lithium iron phosphate battery. Always connect any
powered accessory to a 12-volt auxiliary outlet or terminal board.
Never connect jumper cables to any of the batteries of this vehicle.
Wear a full-face shield and rubber gloves and use only insulated tools when working in the
battery compartment.
If the lithium iron phosphate battery is damaged, the entire battery must be replaced. The user
may not be dismantling any parts or repair.
6.1.2 Number of Battery Cycles
New lithium iron phosphate battery can initially hold all of their capacity. The approximate capacity of
the lithium iron phosphate battery pack decrease as the number of charge cycles increases.
