Volantex Tumbler Owner's Manual - page 4
However, even before this reduction in power , if you find that more than the typical amount of
throttle/ power is required to power up, you should return the model and disconnect the battery
immediately to prevent over-discharge. And while it is possible to continue running the model after
the soft LVC occurs, this is
NOT recommended
. Continued discharging can result in reaching the
5.0V ‘hard’ LVC which may cause permanent damage to the LiPo battery resulting in reduced
power and running duration during subsequent running ( or failure of the battery entirely which is
not covered under warranty).
!
!
Also, it is not recommended that you run to the soft LVC every time you run. Instead you should be
aware of the power level of the battery through out, and if at any time the model begins to require
more throttle/ power than typical to maintain speed you should let the model return back and
disconnect the LiPo battery immediately. Constantly discharging the battery to the soft LVC can still
cause permanent damage to the battery so it’s best to use a timer or stop-watch to time the
duration of your running and to stop at a reasonable time before the soft LVC is reached.
!
It can sometimes take a few hours or even up to a few days to over-discharge the battery this way
but doing so will likely cause permanent damage to or failure of the battery entirely (which is not
covered under warranty).

IMPORTANT NOTE: DO NOT STORE THE LIPO FLIGHT 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 voltmeter 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 use (as long as the battery was not over-discharged on the last use).

IMPORTANT NOTE: DO NOT LEAVE THE LIPO BATTERY CONNECTED TO THE ESC UNLESS
YOU ARE READY TO RUN. IF THE BATTERY IS LEFT CONNECTED TO THE ESC WHEN IT IS
NOT IN USE THE LIPO BATTERY WILL BE OVER-DISCHARGED BY THE SMALL AMOUNT OF
CURRENT THE ESC CONSUMES.
