Safety notes: Please note that removing or damaging the protection electronics (PCB) can lead to a short circuit, fire, or explosion. Additional features: Lithium-Ion batteries are thermally stable and do not suffer from memory effect. They operate on the basis of lithium and are characterized by high energy density. Technical specifications for "Keeppower 18650 - 3400mAh, 3.6V - 3.7V Li-Ion battery protected." Normal charge current 1650mAh/3.5h. Fast charge current 2000mAh/3h. Operating temperature charging 0 °C - 45 °C. Operating temperature discharging -20 °C - 60 °C. Notes: Charging lithium-ion batteries requires a special charger that charges the batteries according to a specific charging method (CCCV = constant current, constant voltage). The batteries must not be charged above a voltage of 4.2 volts, as there is a risk of fire and explosion.
