Charge current 0.xx - 3.2A. Charge cut-off voltage is 3.65V. Integrated protection is not available. Positive terminal (design) is flat (Flat Top). Composition (chemistry) is LiFePo. Diameter is 26.10 mm ± 0.15 mm. Height is 66.00 mm ± 0.20 mm. Weight is 86 g. Charging method is CC-CV.

Safety notes: Lithium cells must only be operated with protective electronics! Please note that lithium cells may only be used by authorized personnel. Improper handling or short circuits can lead to fire or explosion.

Additional features: Lithium iron phosphate batteries are thermally stable and do not suffer from memory effect. They operate based on lithium and are characterized by high energy density.

Notes: Charging lithium iron phosphate batteries requires a special charger that charges the batteries according to a specific charging procedure (CCCV = constant current, constant voltage). The batteries must not be charged beyond a voltage of 3.65 volts, as this poses a risk of fire and explosion. It is advantageous to charge the batteries only up to about 3.5 volts, as this significantly increases the lifespan and number of charge cycles (potentially up to a doubling).
