Have you ever been out flying and wished you had a way to charge more packs but didn't have any way to plug in your charger? Now you can charge your flight packs while on the go with this Ultimate Mobile Battery Charging Station Bundle!

By utilizing a energy dense Lumenier 22000mAh 4s Lipo Battery as the power source for your battery charger you can now charge batteries no matter where you are. Simply pre-charge the 22000mAh battery before you leave and you have a massive 370 Watt hours in the palm of your hand! This means you can charge your smaller flight batteries with this big field charging battery.

How many batteries can I charge?

Good question! It comes down to total watt hours available from your source battery as the power supply and then how many mAh and what voltage your flight packs are. Here are some estimations of what you can expect to get:

22000mAh 4s battery can charge (estimated):

• 22x 1300mAh 3s batteries
• 17x 1300mAh 4s batteries
• 11x 1300mAh 6s batteries

It is not suggested to drain the main power battery below 3.5V per cell. Never fully drain a LiPo battery as it can damage the cells. We suggest using a balance plug low voltage alarm buzzer to help notify you when the battery is too low.

How should I store the big 22000mAh battery?

Like any LiPo battery safety is very important when charging and storing the packs. There is a lot of energy stored in these packs and following best practices is paramount.

• Always store your batteries in a safe, non-flammable location, and in a temperature controlled environment.
• When the battery is not in use be sure to store it at a safe 3.7-3.8V per cell level. Leaving the battery fully-charged or under-charged for long periods of time can damage the battery or cause failure.
• Never leave an actively charging/discharging battery unattended
