LED Indicator
The NeverDie® Compact Battery has a LED
integrated into the power button on the unit itself.
Some models may have provisions for a remote
LED and power button, but their function
remains the same. Refer to the table below for an
explanation of the LED blink patterns.
Battery Functions
This battery is Bluetooth compatible. Monitor
battery voltage, state-of-charge, temperature,
current and status code remotely from your
mobile device. Download in IOS at the Apple App
Store or for Android download in Google Play.
Reserve Voltage Cutoff (RVC)
NeverDie® function. During discharge the
BMS will disable discharge current when the
battery voltage reaches the RVC level, which
allows the battery to store a small energy reserve.
Once the battery is in the RVC state you can
access the reserve capacity by a short-press of the
Power button.
Low Voltage Cutoff (LVC)
During discharge the BMS will disable
discharge current when the battery voltage
reaches the LVC level. Charging current is
allowed, so that the battery can be charged by
activating a charging source. Some charging
sources require to “see” the battery voltage
before allowing charging, in which case LVC
lockout can be temporarily overridden by
holding down the Power button. This override
will allow the charger to sense the battery
voltage, so charging can begin.
High Voltage Cutoff (HVC)
During charging, the BMS will disable charge
current if the battery voltage reaches the HVC
voltage level. This should not happen during
normal operation if charging sources are setup

Storage
If the battery needs to be
stored for >3 months the
voltage should be 13.2V
(50%SoC) and stored to the
recommended storage
specification shown above.
Additionally, the battery needs
at least one charge &
discharge cycle every 6
months. Turn the battery off
when placed into storage.
