Power Ion RB 3100 - They are a basic set with a capacity of 3.1Ah for powering the on-board system.
Important warning (relevant notifications):
Power Ion accumulators do not need to be balanced when charging.
Charge only with Li-Ion/Li-Po battery chargers with voltage limitation to 4.2V per cell
Do not discharge the accumulator below 2.5V per cell
Do not discharge the accumulator beyond the maximum discharge currents listed.
Do not charge at currents higher than those listed as maximum charging currents.
Prevent any short circuit, short circuiting usually leads to irreversible destruction of the accumulator.
Prevent accumulator cells from overheating above 80 °C.
Do not use accumulators with a damaged housing cover or insulating foil.
Avoid contact with water and other liquids.
Mishandling of the accumulator may cause explosion, injury, fire.
