Lithium polymer batteries don't come cheap! But with a little bit of care, you can make the most out of your battery and maximize its lifespan.
Like all batteries, lithium polymer batteries slowly wear out from the day they were manufactured. How long they'll last depends on the temperature at which you store the batteries and how you charge and discharge them. You can also buy lithium polymer battery pack from online sources.
Here's a quick guide to helping you care for your lithium polymer batteries and keep them in peak condition.
Store your batteries in a cool, dry place
While lithium polymer batteries are highly resistant to changes in temperature, you should never leave them in a place where the temperature may exceed 60 degrees Celsius. Ideally, the batteries should be stored inside a LiPo sack and kept in a cool, dry place with a stable temperature of 4 to 20 degrees Celsius.
Store your batteries with a 50% charge
As a standard rule of thumb, lithium polymer batteries should not be stored in a fully charged state for an extended period of time as that dramatically reduces their lifespan. Bearing in mind that the batteries slowly degrade over time, you should also never store them when they're nearly flat because they will fall into a deep discharge stage and these damages the battery cells.
Use the right charger that has been approved for lithium batteries
Not all chargers are suitable for lithium-based batteries. Mobile phone chargers for example, operate at different voltages that may slowly wear out lithium polymer batteries. For safety reasons, you should always charge your batteries in a well-ventilated area that is clear of any flammable items or liquids. Check your batteries for punctures or physical signs of ballooning.
