Safety Advantage
Air vent with double protection functions ensures safety
The World's first controllable air vent with double protection functions is a patented product. It exhausts and opens automatically in one-way mode at different pressure.
Good insulation and lightning resistance in the wild
Plastic shell has good insulations.Cells can be assembled into a DC-high voltage battery pack directly. Insulation ability is not affected by air humidity.Good anti-lightning performance without grounding.Not easy to generate static electricity and cause accidents due to friction generated by electric sparks.
Decompression design in special circumstances
Plasitic shell has low melting point(170℃).It melts and makes decompression automatically in the extreme conditions to ensure.
Matters needing attention
(1) Please check if spare parts are completed when open the package and read the operation manual carefully.
(2) Do not make the battery Short Circuit,do not over charge and discharge.
(3) Please charge the new battery to full capacity before discharge for the first use.
(4) The battery pack is fixed with plate and strip before delivery, do not disassemble the plate and strip when using the battery.
(5) Checking the voltage of battery, normally it is 3.2V-3.3V.
(6) Fix BMS for battery pack and protect single cell to avoid over charge and over-discharge.
(7) Please use copper part to connect battery packs and fix with hydraulic pressure plier. We could also provide the relevantconnection which fixed with screws.
(8) The charger used should be approved by our company in order to match with our lithium batteries.
(9) It will shorten battery cycle lifetime and damage battery due to overcharge and over-discharge if not do according to the above . It won’t be within our company warranty.
