battery;

After the battery product is over-discharged, it is recommended to charge the battery within 48
hours. The battery product can also be charged in parallel. After the battery product is
connected in parallel, the charger only needs to connect the output port of any product battery.

Never attempt to open or dismantle the battery! The inside of the battery does not contain
serviceable parts.

Disconnect the Li-Ion battery from all loads and charging devices before performing cleaning
and maintenance activities.

Place the enclosed protective caps over the terminals before cleaning and maintenance
activities to avoid the risk of contacting the terminals.
7.2 Inspection

Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage or
damage of any other kind. If damage to the battery is found, it must be replaced. Do not attempt
to charge or use a damaged battery. Do not touch the liquid from a ruptured battery.

Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-
discharge when not in use or whilst in storage.

Consider replacing the battery with a new one if you note either of the following conditions:
- The battery run time drops below 80% of the original run time.
- The battery charge time increases significantly.
7.3 Cleaning
If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives
to clean the Li-Ion battery.
7.4 Maintenance
The Li-Ion battery is maintenance free. Charge the battery to approximately > 80% of its capacity at
least once every year to preserve the battery’s capacity.
7.5 Storage

The battery product should be stored in a dry, cool and cool environment;

Generally, the maximum storage period at room temperature is 6 months. When the battery is
stored over 6 months, it is recommended to check the battery voltage. If the voltage is higher
than 48V, it can continue to store the battery. In addition, it is needed to check the voltage at
least once a month until the voltage is lower than 48V. When the voltage of the battery is lower
