Product advantage
(1). Lithium batteries are light in weight, small in size, large in
capacitance, high in energy and high in safety
(2). Lithium battery core raw materials. The core itself has
overcharge, overpressure, and overlet the flow of
four safety protection. It fundamentally solves the hidden dangers of short circuit, leakage, explosion and other
aspects of lithium batteries.
(3). Lithium batteries use lithium battery cores in series.
(4). Charging chip protection plate(using military-grade smart IC
chip, with overcurrent, overpressure, overcharge,
overcharge, undervoltage, short circuit, reverse connection, equilibrium voltage and equilibrium charging and
other multiple protection functions) to ensure the safety and
reliability of the battery pack.
(5). Lithium batteries are used for a long time. The cycle can be
charged and discharged more than 600 times.
LED light source operating time of 20,000 hours, lithium battery life 2-3 years.
