CHARGING INSTRUCTIONS
BATTERY CHARGER
The battery charger takes the standard wall outlet voltage (alternating current) and
converts it into DC voltage (direct current).The batteries use direct current to run your
power scooter. When the batteries are fully charged, the amperage from the charger
is almost at zero. This is how the charger maintains a charge but does not
overcharge the battery.
Note 1: The batteries cannot be charged if they were discharged to nearly zero voltage.
Note 2: The power scooter meet the requirement of ISO 7176‐14:2008 and ISO
7176‐21:2003.
Note 3: Only use the battery charger type which was provided by the supplier.
The use of any different type of charger can be hazardous and need the approval of the
manufacturer.
ON/OFF SWITCH
Make sure the charger is not connected to the scooter and they key is not in the
ignition switch and to ensure connect the batteries. Then turn the on/off switch to the " I
" position to be abled to pass power to the scooter. Then you will see the two lights in
the rear will lit up. Then press the green button in the rear of the scooter to unfold.
Turn off the side button to "O".

DESCRIPTIO
NL07C-25HT is a smart charger specially designed for Li-ion battery pack composed
7cells in series.
Electrical Specifications:
1. Input : 100~240VAC, 50/60 Hz Output: 29.05V± 0.2V 2.5Adc ± 10%
2. Charger output：The charger is preset by factory for charging 7 cells Li-ion battery
pack.
Its charging mode:
1) Constant current (CC) mode: at beginning of charging, an 2.5Adc±10% (I (ave) )
constant charging current to charge the pack until the pack voltage reaches to
29.05V± 0.2V.
2) Constant Voltage (CV) mode: the output will keep 29.05V±0.2V constant through
the end of charging.
3) Pre-charge state: When battery voltage is lower than 21V±1V, will start the pre-
charge first. The charge current is 30% of CC charge current: 0.75Adc ± 10%.
Once unfolded, insert the key in the ignition key to be
