General Charging Information

Below is a picture of a FlightPower EVO20 3s1p 1800mAh pack being charged with a Schulze Chameleon 636 through a FlightPower V-Balancer unit. The V-Balancer unit is an intelligent balancing device that connects between the charger and battery allowing it to control the charge reaching each cell, it will effectively equalize all cell voltages in the pack and at the end of the charge the result is a fully balanced pack.

Caution: Maximum care and appropriate equipment in the area of charging are mandatory for the safe operation of Lithium Polymer batteries.

A lithium Polymer compatible charger is the minimum requirement. With Lithium Polymer (and Lithium Ion) battery types there is no delta peak to for a delta peak charger to detect and therefore the use of a NiCd or NiMH charger or a multifunction charger set to NiCd or NiMH mode is expressly dangerous (fire hazard).

Lithium Polymer battery chargers operate using a CC+CV charging profile, this means that the current (Amps or Milli-Amps) set will apply to the charge cycle during an initial "Constant Current" mode until the voltage of the pack reaches around 4.0V per cell. After this the charger will change mode to Constant Voltage charging and will terminate when the pack is drawing only a very small amount of current.

Charge Rate - The FlightPower EVO 20 range should normally be charged at 1C during the Constant Current phase of charging (the charge current setting on the charger). This means that an EVO 20 1800 mAh pack should normally be charged at 1.8 Amps (or 1800 Milli Amps). This will result in a pack that is 90% full in around 1 hour.

Fast Charging - In conjunction with Enerland, the FlightPower EVO 20 range has been qualified for 2C charging as a combination of cell technology and matching by FlightPower at the point of manufacture. This means that an EVO20 1800 mAh pack can be fast-charged at 4.5 Amps (or 4500 mAh). This will result in a pack that is 90% full in around 25 minutes. (All) fast charging of rechargeable chemistry results in a reduction in cycle life, it is therefore recommended that fast charging be done when time is of the essence.
