lithium polymer flight battery

Charging lead only
The LiPo flight battery is a high power battery designed to give a flight time of approximately 10mins per charge. It is
supplied in a partially charged state.
As well as a red deans style conector lead (for connection to the ESC) the battery is also fitted with a white 3-pin
polarised connector. This is the charge lead. Connect this white plug to the 12V charger. Always leave the battery in a
partially charged state. Never leave it in a discharged state.
The battery should be charged if you notice the model losing power. At this point land and recharge the battery.
Do not be tempted to run the battery past this stage as you will be over-discharging and the battery may be damaged.
WArnInG!
We recommend that you use only the supplied escale charger with this battery.
WArnInG!
over-discharging will shorten the life of the battery or destroy it. stop flying immediately you notice the model is
losing power and recharge the battery.
WArnInG!
Do not short circuit—battery may explode!
