Advantages
① High rate charge/discharge
100mohm low ESR and high rate(10C,240mA) enabled by optimizing materials and structure
② High safety
No thermal runaway occurs because of its low capacity and chemically stable materials.
This product received safety standard, UL1642 and IEC61233 certification.
③ Long cycle life
Charge (capacity) recovery is over 90% even after 5000 cycles. It can realize maintenance free design
