Charging Instruction(RTF)
Lithium Battery
Balance Charger
1. Plug the included balance charger to the power adaptor cable, then plug the power adaptor into a
compatible AC outlet(depends on different contries and area) , then connect the power output lead to the
receptacle on the side of the balance charger The power adapter and balance charger are powered on whe
n the green color LED indicator is glowing.
2. Connect the white connector from battery to the mating connector on the charger. And while the white
connectors are ‘keyed’ to minimize the risk of a reverse polarity connection, if you force them it is possible
to make connection with the incorrect polarity potentially causing damage to the battery and/or charger.
When the connectors are properly aligned for correct polarity, connecting them should require only a
moderate amount of pressure to achieve the ‘click’ that indicates a secure connection.
3. When the battery is connected to the charger securely and with the proper polarity both the red color and
green color LED indicators will glow. The battery will be charging anytime the red LED indicator is glowing.
4. It will take approximately 1.5-2.5 hours to fully charge a mostly or fully discharged (not over-discharged)
battery. And when the battery is fully charged the red LED indicator will stop glowing entirely. When the red
LED indicator is no longer glowing you can disconnect the battery from the
charger as it is now fully charged
and ready for use.
CAUTION: Do not store the lithium battery fully charged.
For improved safety and longevity of the LiPo battery it’s best to store it only partially charged for any length
of time. Storing the LiPo battery at approximately 50% charged (which is approximately 3.85V per cell) is
typically best, however it will take some careful management of the charge time and the use of a volt meter
to achieve this voltage.
If you have the equipment and skills to achieve the 50% charge level for storage it is recommended. If not,
simply be sure to not store the battery fully charged whenever possible. In fact, as long as the battery will
be stored at approximately room temperature and for no more than a few weeks before the next use, it may
be best to store the battery in the discharged state after the last
(as long as the battery was not over-
discharged on the last
