FlightPower Balancers / Accessories

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 hazzard).

Lithium Polymer battery charges 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 2.5C charging as a combination of cell technology and matching by FlightPower at the point of manufacture. This means that an EVO 20 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.

Balancing

Cell balancing (as oposed to cell matching) is the process of equalising the voltages of each cell in a pack. The open-circuit voltage of each cell and during charging is normally a good analogy to the state of charge. Equalising the charge state and resisting / preventing overcharging at the cell level is good maintenance practice and will normally result in improved performance, improved cycle life and increased safety.

Balancing Methods:

i. Manual, using the appropriate FlightPower Diagnostic lead it is possible to charge and discharge cells individually as "1S" using a charger with a discharging function or another low current DC load. Match voltages with a meter.

ii. Using a cell balancer module such as the Duralite/FlightPower Staybalance module, a true equalising balancer. This means that it will analyse the charge state of each cell in the pack whether on charge or not, and then attempt to discharge any cell that has a higher voltage than the lowest common denominator. This type will also attempt to discharge any cell that exceeds 4.21V. Using this kind of balancer, the pack is charged through the main power leads.

iii. Pass-through balancer such as the V-Balance module, this kind of balancer performs in a similar manner to the cell balancer module except that the during charging the battery is connected to the balancer and the balancer manages the charging of each cell individually. This kind of balancer is able to switch off the current to any cell exceeding 4.21V to prevent overcharging.

iV. Balancing charger. A balancing charger charges the pack through the balancer connector and not through the main power leads. Each cell is charged individually and overcharge protection is inherent to the charge method.*Note, please check the final voltage delivered by some budget balancing chargers and ensure the pack is taken off charge as soon as it is at 4.21V per cell.
