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

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

Technical specifications for "A123 ANR26650M1B 2500 mAh 3.3 V LiFePo4 battery": Notes: Charging lithium iron phosphate 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 3.6 Volts, as this poses a risk of fire and explosion. It is advantageous to charge the batteries only up to approximately 3.5 Volts, as this significantly increases their lifespan and number of charge cycles (potentially up to doubling).
