How to preserve the battery lifespan
All Flymaster instruments use Lithium-Ion batteries. Compared with traditional battery
technology, lithium-ion batteries charge faster, last longer, and have a higher power density
for more battery life in a lighter package.
The Flymaster lithium-ion battery uses fast charging to quickly reach 80% of its capacity,
then switches to slower trickle charging. The amount of time it takes to reach that first 80%
will vary depending on your settings and which instrument you're charging. This combined
process not only lets you get out flying sooner, but it also extends the lifespan of your
battery.
Charging is easy
Charge your Flymaster lithium-ion battery whenever you want. There's no need to let it
discharge 100% before recharging. Flymaster lithium-ion batteries work in charge cycles.
You complete one charge cycle when you've used (discharged) an amount that equals
100% of your battery's capacity - but not necessarily all from one charge. For instance, you
might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you
use 25% the next day, you will have discharged a total of 100%, and the two days will add
up to one charge cycle. It could take several days to complete a cycle. The capacity of any
type of battery will diminish after a certain amount of recharging. With lithium-ion batteries,
the capacity diminishes slightly with each complete charge cycle. Flymaster lithium-ion
batteries are designed to hold at least 80% of their original capacity for a high number of
charge cycles, which varies depending on the instrument.
Avoid extreme ambient temperatures
Your instrument is designed to perform well in a wide range of ambient temperatures, with
5° to 25° C as the ideal comfort zone. It's especially important to avoid exposing your
instrument to ambient temperatures higher than 35° C, which can permanently damage
battery capacity. That is, your battery won't power your device as long on a given charge.
Charging the device in high ambient temperatures can damage it further. Even storing a
battery in a hot environment can damage it irreversibly. When using your device in a very
cold environment, you may notice a decrease in battery life, but this condition is temporary.
Once the battery's temperature returns to its normal operating range, its performance will
return to normal as well. Store it half-charged when you store your instrument long term.
