4-5. Installation of Battery in Parallel
4-6. Installation Precautions
(1) Prior to installation, unpacking to check the quantity of the parts and battery appearance.
(2) Different brands of batteries or new and old batteries cannot be used in parallel.
(3) Static voltage differences ≤ 0.2V, SOC differences ≤ 5%, internal resistance differences ≤ 2mΩ can be
used together in parallel.
(4) Install the hanger and handle and measure the battery voltage with a multimeter. The general factory
voltage of the battery is 48V-50.25V.
(5) Prior to wiring, check the anode and cathode of the battery and the anode and cathode terminals shall not
be connected reversely.
(6) During battery connection, please wear the protective gloves. When using such metal tools as torque
wrench, please perform insulating packaging for them and two end of the metal tools such as torque
wrench shall not contact the positive and negative terminals of the battery at the same time to avoid
battery short-circuit.
(7) Before the battery is connected with the externally connected equipment, make the equipment in a
disconnected state, check whether the connecting polarity of the battery and total voltage are correct,
connect the battery anode with the equipment anode and battery cathode with the equipment cathode
and fix the connecting line.
(8) During handling and placement, the battery must be handled gently. No dropping or impacting. The
battery shall not be thrown or beaten to avoid damaging the battery or resulting in potential safety hazard.
(9) Do not touch the surface of the battery box with the sharp part of the tool to scratch or damage the
battery box.
(10)Do not disassemble the battery box without authorization.
