Our Specialties
1.Our battery blocks are assembled in a battery cases made of synthetic material, which not only stabilize the block, but also increase its lifespan. Li-ion cells warms up during the charging and discharging process; the protection cases maintain space between the cells, so the warmth spreads on the surface.
2. Connections are welded with nickel-based alloys (more than 95% nickel) and not with iron-based alloys. This alloy has a better high-temperature resistance, is robuster and has a lower internal resistance.
3. Use of FR4-isolation: these flame-resistent and  flame-retarding composite materials consist of epoxy resin and fiberglass reduce the danger of short circuits and combustion of  textiles (carrying bags etc.)

BMS Feature
ASIC chip, high precision acquisition, automotive grade material, Lightning Surge Immunity Test, redundancy design, high temperature aging, electron- static discharge, EMC, current balancing technology, maintenance-free battery system, The water detection, smoke detection, collision warning system actively.
FEEDBACK

Temp. Balance & Bonding
Aluminum wire bonding process with bus-bar design, triaxial vibration design, waterproof and dust proof design, structure lightweight design technology, which solved the core issue of power battery, improving the safety, reliability and stability. At the same time, the problem of BATTERY heating, heat dissipation was managed by temperature equalization technology ,which improve the battery performance and life span. PLB continue to optimize the battery pack design, so as to ensure the safety of product.

The power storage module is a battery that can store energy, detect power outages, and automatically become your home’s energy when the grid fails. Unlike gasoline generators, battery bricks can keep your lights on and your phone charged without maintenance, fuel or noise. Pair with solar power and charge Keep your appliances running in the sun for several days.
The storage brick reduces the dependence on the grid by storing solar energy, because the storage brick is a battery that can store energy and detect power failure And when the power grid fails, it will automatically become your home’s energy source. Unlike gasoline generators, battery bricks keep your lights on all the time Charging with phones requires no maintenance, fuel or noise. Pair with solar power and charge in the sun to keep your appliances running for several days.
