Product Description


Cylindrical shape cell is the most cost-effective cell type since it is easy for mass production. And due to its production technology is quite mature today, the cell quality can be well controlled. HECO cylindrical cells are mainly in 26650 size. The capacities are from 3000mah to 4000mah with both high energy type and high power type. Highest energy type cell can be 4000mah at max. constant 2C discharge rate. Highest power rate cell is 3000mah at max. constant 10C discharge rate. In 2019, Heco developped low-temperature cells which can support charge under -30℃ (at 0.2C charge rate) and can support discharge under -50℃ (at 3C discharge rate) with 90% efficiency.



Quick Detail:
1. High capacity: 4000mah 
2. High safety: lithium ion phosphate chemistry ensures its excellent safety performance
3. Long cycle life: 2000+ cycles @ 100% DOD
