With their light weight and large charge capacity Lipo battery packs are perfectly suited for use with all kinds of RC helicopters. They have one problem.
Lipo (Lithium Ion) battery packs have a shorter useable lifespan (a shorter number of recharge cycles) than the more traditional Nickel Cadium battery packs used in the past.
In fact, most Lipo packs deliver only 300 to 400 charge cycles before they need to be replaced depending on how hard you fly.
“Most Lipo packs should be replaced after 300 to 400 charge cycles”
And even though electric power is still the less expensive way to go over Nitro fueled models, who wants to be forced to constantly buy new battery packs to keep your heli flying?
Fortunately there are a few simple tricks you can do to extend the life of your battery pack so you can spend more of your time flying and less time online shopping for the next replacement for your worn out old LiPo pack.
Breaking In New Battery Packs
Did you know that many manufacturers suggest putting your model through a short “break-in period” before pushing the power demands on a newly installed battery pack?
You can extend the life of your batteries by simply “going easy” on the battery pack for the first few flights after installing a new battery pack in your model.
“Extend the life of your batteries by simply “going easy” on the battery pack”
By keeping your flight times down to around 5 minutes after installing a fresh battery pack and avoiding pushing your heli to full throttle you will “condition” your battery pack which will significantly improve the performance of your flight pack .
To get the best results you should condition your batteries in this way for the first 4 to 6 flights after installing a new battery pack allowing a 15 minute break between flights to allow your batteries to cool down.
7 More Tips to Get The Most From Your Battery Pack
• Don’t cut corners. Buy the best battery pack you can afford it pays dividends in the long run.
• Chargers that come bundled with many models are marginal at best, upgrade to a better charger whenever possible.
• Get a charger that has a built-in voltmeter or pick up a multi-meter separately so you can easily monitor the condition of your batteries.
• Avoid charging your batteries after each flight if they are still hot to the touch.
• When planning to store your batteries for a long extended period of time, avoid storing them with a full charge. Instead discharge them after a normal flight and store them with only small charge on the battery.
• LiPo battery packs do not have a “memory” so there is no need to cycle the batteries like traditional NiCad battery packs. In fact, cycling your battery pack will actually reduce the batteries performance.
• Avoid overcharging. Overcharging a battery will reduce the batteries ability to hold a charge.
LiPo Battery Handling & Storage
- Keep LiPo battery packs WELL out of reach of children.
- Do not put battery packs in pockets or bags where they can short circuit.
- Do not store or transport or store batteries where they can come into contact with sharp or metallic objects.
- Do not store your LiPo pack in extreme temperatures below 0C or above 50C.
- Always store your LiPo pack in a safe and non flammable container away from flammable objects. A LiPo Sack or metal / ceramic storage container is best.
- Always store your LiPo’s partially charged. They will maintain their performance levels over time and there’s no need to cycle them unless stored for periods longer than 3-6 months.
