LipoShield intelligent lithium cutoff
LipoShield is a low voltage cutoff device which enables any
ESC to be used with lithium battery packs. It installs easily between
and ESC and provides a reliable 3.0V per cell soft cutoff to prevent
over-discharge damage to your expensive lipo packs.
LipoShield is a soft cutoff, so it is appropriate for any plane,
even 3D types. The soft cutoff gradually reduces power to the motor
allowing you to make a controlled landing.
When you notice the aircraft becoming sluggish, it is time
to bring it in. The cutoff can be reset by throttling down to zero,
then throttling back up. This enables a “go around” to
prevent emergency landings and long walks to retrieve your plane.
LipoShield automatically detects the number of lithium cells
in your battery pack at power-up and sets the appropriate cutoff
voltage. It then continuously displays the detected number of cells by
blinking the “Cells” LED. LipoShield works whether
you’re running a BEC built into your ESC, a separate BEC such
as ParkBEC or even a receiver pack.
LipoShield uses a microcontroller to modify the throttle
signal sent from the receiver to the speed control. As a result, it works
equally well with older ESCs that have no lithium cutoff settings, and
new ESCs that have unreliable cutoffs. It will even work in conjunction with
another soft cutoff built into your speed control.
LipoShield works equally well with brushed or brushless ESCs.

LipoShield is intended for aircraft with 0-100% style one direction
only throttle. A future product will be aimed at cars.
