Protection against overcharging and deep discharge
The detection of value outside the scope protects the cells from damage.

Cells containing SiO - silicon carbide
Increased efficiency of lithium-ion battery, up to 20%

Protection against short circuits
At the time a threat of short circuit is detected, the device shuts off the cell and electronics automaticall.

Monitoring voltage and amperage
Exceeding the entered parameters results in disconnecting the power supply.

Temperature resistance
The temperature control makes the cells operate in a safe range.

Cells 805294 from Panasonic
GC Ultra have 18650BF cells, which increase the capacity of the battery to 6800 mAh without physical enlargement.
