Lithium ion batteries are common in consumer electronics. They are one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defense, automotive, and aerospace applications due to their high energy density.
Lithium batteries are lighter than other equivalent secondary batteries-often much lighter. The energy is stored in these batteries through the movement of lithium ions.
The lithium ion electric bike battery is more safe and reliable than the lead acid one. It does not explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat. Environment-friendly: Accredited with CE, without any hazardous and noxious substances. compacted in volume and light in weight.
