A fully decoded chip communicates with the radio exactly as the factory unit does. ISO9001, RoHS and CE certifications confirm compliance with recognised safety and environmental standards. Shock-absorbing foam in the packaging protects the pack during transit.
Thermals, Noise and Power Draw
Lithium-ion chemistry runs silently and produces no audible noise in normal operation. The pack delivers 17.02Wh at 7.4V, supporting extended indoor or outdoor shifts. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits. The manufacturer notes that two or three full charge cycles bring the cell to peak capacity. Do not store above 60°C.
