> It is strongly recommended to use an ESC which is designed to handle the low voltage cutoff points or
Lipo batteries (Always follow the instructions provided with the ESC for proper operation). Discharging
Lipo batteries below 2.5V per cell (Norm is 3.7V per cell, at 4.2V once fully charged) can cause
permanent damage and limit the number of times the battery can effectively be used again.
> Never discharge Lipo batteries at currents which exceed the discharge current rating of the battery
as this can often cause a cell to overheat. Do not allow a Lipo cell to exceed 60˚C (140˚F) during
discharge.
Caution!
Cells may be hot. Do not allow the battery's internal electrolyte to get in the eyes or on skin. Wash
affected areas with soap and water immediately if they come in contact with the electrolyte. If electrolyte
makes contact with the eyes, flush with large amounts of water for 15 minutes and seek medical
attention immediately.
Carefully inspect Lipo batteries which have been involved in a crash for even the smallest of cracks,
splits, punctures or damage to the wiring and connectors.
Disposal of Lipo batteries
Unlike Ni-Cd batteries, Lithium-polymer batteries are environmentally friendly. For safety reasons,
it's best that Lipo cells be fully discharged before disposal (however, if physically damaged it is
not recommended to discharge Lipo cells before disposal). The batteries must also be cool before
proceeding with disposal instructions. To dispose of Lipo cells and packs:
> If any Lipo cell in the pack has been physically damaged, resulting in a swollen cell or a split or tear in
a cell's foil covering, do not discharge the battery.
> Place the Lipo battery in a fireproof container or bucket of sand.
> Connect the battery to a Lipo discharger. Set the discharge cutoff voltage to the lowest possible value.
Set the discharge current to a C/10 value, with "C" being the capacity rating of the pack.
> Discharge the battery until its voltage reaches 1.0V per cell or lower. For resistive load type
dischargers, discharge the battery for up to 24 hours.
> Submerse the battery into bucket or tub of salt water. This container should have a lid, but it does not
need to be air-tight. Perhaps a bucket or tub containing 3 to 5 gallons of cold water, and mix in 1/2 cup
of salt per gallon of water. Drop the battery into the salt water. All the battery to remain in the tub of salt
water for at least 2 weeks.
> Remove the Lipo battery from the salt water and place it in the normal trash.
Terminology
Electronic speed control (ESC)
An electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to
act as a dynamic brake. ESCs are often used on electrically-powered radio controlled models.
An ESC can be a stand-alone unit which plugs into the receiver's throttle control channel or incorporated
into the receiver itself, as is the case in most toy-grade R/C vehicles. Some R/C manufacturers that
install proprietary hobby-grade electronics in their entry-level vehicles, vessels or aircraft use onboard
electronics that combine the two on a single circuit board.
Brushless DC motors (BLDC motors, BL motors)
Also known as electronically commutated motors (ECMs, EC motors). BLDC motors are synchronous
electric motors powered by direct-current (DC) electricity and having electronic commutation systems,
rather than mechanical commutators and brushes. The current-to-torque and voltage-to-speed
relationships of BLDC motors are linear.
