•Do not use this equipment in sandy water or waters with similar physical properties.
•Do not use this equipment in case of any damage or malfunction.
•The product buoyancy is affected by the geographical location, temperature, depth, and water
flow, and may sink when the product is released.
•Remove the equipment out of the water when not in use.
•Before charging, take the rechargeable battery out of the equipment.
•If the equipment is to be stored for a long time, the battery should be taken out and the power
terminals should not be short-circuited.
•The remote control and headlamp lighting system include a non-replaceable polymer lithium
battery.
•When charging the battery, the ambient temperature range should be 10°C (50°F) ~45°C (113°F).
The storage ambient temperature should be below 45°C (113°F).
•Connect the positive and negative poles of the battery correctly, reverse charging is strictly
prohibited. If the positive and negative poles of the battery are connected inversely, the battery
will not be charged. In addition, reverse charging will reduce the charging and discharging
performance and safety of the battery, and will lead to heating and leakage.
•The charging current should not exceed the maximum charging current specified in this manual. If
the charging current is greater than the recommended value, the charging and usage
performance, mechanical performance and safety performance of the battery may have problems,
which may lead to heating or leakage. The charging voltage shall not exceed the rated voltage of
DC 25.2V specified in this manual, and DC 25.5V is the maximum charging voltage. When the cell
voltage is higher than the rated voltage, it may cause problems in the charging and usage
performance, mechanical performance and safety performance of the battery, and may cause
heating or leakage.
•The battery storage voltage is 22.2V~23.1V. Storage while fully charged is not suggested.
•Do not directly connect terminals with metal objects. This will short-circuit the battery, causing
heating and discharging.
•Only the charger designed for lithium polymer/lithium-ion battery can be used. Do not use NIMH/
NICD/ LIFEPO4/ lead-acid charger. If the charger can support different battery types, be sure to
select the lithium polymer (Lipo) mode on the charger. Otherwise, it may cause fire, resulting in
personal injury and property loss.
•Always charge the battery in an open area away from flammable materials, liquids and surfaces.
•Do not charge the battery if it is very hot (above 37.8°C /100°F). Do not charge the battery until it
has cooled down.
•Do not replace the battery under water. When replacing the battery, make sure to do it in a dry
environment and keep the equipment and hands dry.
•The battery cannot be disassembled, modified, or subjected to strong vibration or impact. Please
handle the battery carefully after installation.
•The battery should not be allowed to get damp and the battery metal socket should not come in
contact with liquids. When you assemble, disassemble and store the battery, please keep the
product and your hands completely dry, and operate in a dry environment.
•If the battery produces abnormal smell, heat, discoloration, deformation or other abnormalities
during use or charging, please stop using or charging immediately. If the above abnormal
conditions occur during the storage of the battery, please inspect the storage environment.
•Do not throw the battery into fire.
•Do not put the battery into a microwave oven, high-pressure vessel, or electromagnetic oven.
•Do not store the battery in an outdoor vehicle or at high temperatures for long periods of time.
•This product should be stored away from direct sunlight. High temperatures will damage the
battery, causing explosion or leakage. Do not repair this equipment without authorization to avoid
leakage, damage, fire, or electric shock.
