Features:
High Capacity:
The capacity of a single 18650 lithium-ion battery typically ranges from 1200mAh to 3600mAh, significantly higher than the average capacity of around 800mAh for general batteries.
When combined into a battery pack, the total capacity can easily exceed 5000mAh.
High Safety Performance:
18650 lithium-ion batteries are designed with high safety standards, featuring no explosion or combustion risks.
They are non-toxic and pollution-free, having passed RoHS certification.
Advanced safety features such as overcharge protection, over-discharge protection, and short-circuit protection enhance their overall safety.
Low Internal Resistance:
The internal resistance of 18650 lithium-ion batteries is relatively low, especially for polymer cells, which can further reduce self-discharge and extend standby time.
