5. Safety Instructions

Use only a professional 4S LiPo balance charger with a standard charging voltage of 16.8V. Do not overcharge.

Stop working immediately when the battery voltage drops to 12.0V. Avoid deep discharge to prevent permanent cell damage.

Do not squeeze, pierce, disassemble, drop or impact the battery. Keep away from high temperature, fire and water.

For long-term storage, maintain half-charge state (14.0V–14.4V) and recharge the battery once a month.

Stop use immediately if the battery generates abnormal heat, bulges or deforms during operation.
