21700 size 5000mAh high capacity 15A high discharge rate rechargeable Li-ion battery
– “Endless” energy
– High energy intensity
– Powerful performance
The new generation in Li-ion rechargeable batteries.
They are characterized by long life, high energy intensity and very strong performance. That’s why they first appeared in the industry
of electric car manufacturing and is planned to be the future in cylindrical batteries.
It is ideal for devices that require a continuous high discharge current of 15A
Below are some safety features in the battery construction structure:
– Innovative anode design with high temperature resistance
– Pressure relief valve that is activated in the event of a rapid increase in temperature
– Internal protection circuit (PTC) to inhibit large current surges
– Microporous outer cover protects sensitive internal components
High performance electronic protection circuit:
– Automatically protects against over-charging, over-discharging and short-circuiting
– It incorporates a high quality electronic battery protection circuit
– Incorporates two powerful MOSFETs in the current regulation module for better performance and excellent current
Below are some external security features:
– It is equipped at both ends with nickel-plated stainless steel protectors that ensure high impact resistance, good electrical conductivity and oxidation resistance
– Coated with durable metal film for protection against abrasion
Low energy costs and environmentally friendly
Using rechargeable batteries is more economical and at the same time helps to reduce the carbon footprint on the planet.
