protection and
BMS built inside to balance protect the battery
48V to 40Ah for EV car
Long life-cycle, 5 to 7-year, up to 2, 000-cycle (while sealed lead
acid batteries only 750-
cycle and NiMH batteries only 500 cycles)
Lighter and smaller, 1/2 size weight of SLA batteries
70% size/weight of NiMH/NiCd batteries
Wide operating temperature, high temperature resistance (-20 to 60
degrees Celsius)
Steady performance
Higher discharge rate for more powerful devices, 1C continuous, 3C
pulse for normal cells and
20C for special design, low self-discharge rate, less than 3%
monthly
No memory effects and highly efficient charge, it can be recharged
anytime, no reduction of
the capacity
Green product, environment-friendly: clean and green energy poses
no pollution on our
environment
