1.52V 17.5Ah battery pack
2. 58.8V 2-3A charger
Battery Operation Instructions:
1. Charge:Connecting the battery pack to the charge controller,
connect the charger to recharge.
2. Discharge:Connecting the battery pack to the load ,connect the
load to discharge.
3. When you combine the battery with series or parallels, if there
are oxidation layer on the surface, you
should brush surface to the metal glow with thin steel
brush to lower the connective resistance to the minimal resistance.
4. When combining with many batteries, if the voltage between the
two electrodes is over 24V, the safe
voltage for human beings, to guarantee the safety, you should not
touch the two electrodes with your body.
1. If shelve a long time suggested that the battery voltage 51-52V,
need for regular recharging (even if
not use), must charge and discharge for three months one time;
2. Do not expose the battery to extreme heat or flame.
3. Do not short circuit, over-charge or over-discharge the battery
4. Do not disassemble or modify the battery pack.
5. Do not handle or store with metallic like necklaces, coins or
6. Do not reverse the polarity of the battery pack for any reason.
7. Do not immerse the battery pack in water or sea water, or get it
8. Use a constant current, constant voltage (CC/CV) lithium-ion
(Li+) battery charge controller.
