The brands of 18650 battery are LGHG2, Samsung 25R, Sony VTC4, Lishen, BYD, BAK BAK, Tuobang Battery and so on.

The 18650 battery life theory is 1000 cycles of charging. Due to the large capacity per unit density, most of them are used in notebook computer batteries. In addition, the 18650 is widely used in various electronic fields because of its excellent stability at work.

BYD

BYD was established in 1995 and listed on the Hong Kong Stock Exchange and Shenzhen Stock Exchange respectively. It is mainly engaged in the information industry of secondary rechargeable battery business, mobile phone, computer accessories and assembly business, as well as traditional fuel vehicles, new energy vehicles and other automotive industries.

Sony VTC42100mAh or LGHD22000mAh

Both can provide high current, good capacity, good voltage and low temperature when working, the performance is very similar, HB6 and HB2 are easy to discharge at 30A, but because of their small capacity, they are rated very low, and their operating temperature is also very low.

LGHB61500mAh

Both HB6 and HB2 have relatively small capacities. They are the only batteries that can be used for very high currents and also have the lowest operating temperature available, and while HB2 is also good, HB6 is cooler, has a larger capacity, and has a higher voltage, so it's the winner of the 30A+ group.
