Lead Carbon
The lead-carbon battery technology of the BLC series uses a nanocarbon material with high capacitance and high conductivity at the negative electrode. This combines the advantages of both lead-acid batteries and supercapacitors for faster recharging. Lead-carbon battery technology provides not only higher energy density, but also high power, fast charging and discharging and longer life than traditional lead-acid batteries. Batteries are currently only available in large 6V and 12V modules, so multiple batteries are required for usable capacities above 6kWh, which is not ideal for large systems, but is suitable for most uses. Also, the rated capacity can only be achieved at a very slow discharge rate of 100 hours (C100) which is not optimal for a hybrid state with full discharge which is likely to be more than 12 hours or less.
The cycle life of 3000 cycles can be achieved at a high temperature of 40 degrees Celsius, so theoretically, they should last longer at lower temperatures.
