Long Cycle Life Best Battery 18650 Rechargeable Battery 3.7v 3000mAh 3500mAh Li-ion Batteries

Short Description:

18650 lithium battery has the characteristics of light weight, large capacity, no memory effect and very good stability, and is widely used in all aspects of life: electric vehicles, electric motorcycles, electric tricycles, electric bicycles, electric scooters, two-wheeled electric balance cars, strong light flashlights, medical equipment, portable instruments, portable lighting equipment, industrial instruments, etc.

The energy density of 18650 lithium battery is the highest among all batteries. At present, the energy density of lithium battery is generally 200~260wh/g, and that of lead-acid is generally 50~70wh/g. Then the weight energy density of lithium batteries is 3 to 5 times that of lead-acid batteries, which means that the weight of lead-acid batteries is 3 to 5 times that of lithium batteries under the same capacity. absolute advantage.
