2. Recommendation: Sony VTC4 2 100mAh or LG HD2 2000mAh.
Both of them can provide large current, good capacity, good voltage and low temperature when working, and their performance is very close. HB6 and HB2 can be easily discharged for 30 years, but they rank lower because of their small capacity and low working temperature.
3. Recommendation: LG HB6 1500mAh.
Both HB6 and HB2 have relatively small capacities, which are the only batteries that can be used for extremely high current and the batteries with the lowest working temperature. Although HB2 is also very good, HB6 has lower temperature, larger capacity and higher voltage, so it is the champion of the group above 30A.
