Safety Precautions
Battery
3.Always provide adequate ventilation around LiFe batteries during charge, discharge, while in use, and
during storage.
4.Do not leave a LiFe battery unattended at any time while being charged or discharged.
Lithium polymer battery(Short for LiFe battery),please use the WFLY special charger only.It is important
to understand the operating characteristics of Li-Fe batteries.
1.Do not attempt to disassemble LiFe packs or cells.
2.Do not allow LiFe cells to come in contact with moisture or water at any time.
Long term storage (more than 3 months),storage temperature≤45°C general storage voltage 3.7-3.9v.
Failure to follow the proceeding precautions can quickly result in severe, permanent damage to the
batteries and possibly result in a fire!
12.Do not store batteries near an open flame or heater
13.Do not discharge LiFe batteries at currents which exceed the discharge current rating of the battery.
6.Always charge LiFe batteries in a fireproof location. Do not charge or discharge LiFe batteries on
carpet, a cluttered workbench, near paper, plastic, vinyl, leather or wood, or inside an R/C model or full-
sized automobile! Monitor the charge area with a smoke or fire alarm.
14.Always store LiFe cells/packs in a secure location away from children.
11.Do not use a LiFe battery if you suspect physical damage has occurred to the pack. Carefully inspect
the battery for even the smallest of dents, cracks, splits, punctures or damage to the wiring and
connectors.DO NOT allow the battery’s internal electrolyte to get into eyes or on skin—wash.affected areas
immediately if they come in contact with the electrolyte. If in doubt, place the battery in a fire-proof location
for at least 30 minutes.
7.Do not charge LiFe batteries at currents greater than the “1C” rating of the battery (“C” equals the rated
capacity of the battery).
10.It is normal for the batteries to become warm during charging, but if the charger or battery becomes
excessively hot disconnect the battery from the charger immediately!! Always inspect a battery which has
previously overheated for potential damage, and do not re-use if you suspect it has been damaged in any
way.
ET08 adopts the power supply mode of lithium battery, and the working voltage adapts to the range of
3.7-6V. Using a power supply that exceeds the operating voltage stroke may burn the machine!
The USB interface of ET08 can be used to charge the common mobile phone charger (5V)!
8.Do not allow LiFe cells to overheat at any time! Cells which reach greater than 140 degrees Fahrenheit
(60°C) should be placed in a fireproof location.
Receiver (RF206S):
Transmitter (ET08):
The receiver's operating voltage adapts to the range 3.8V-6.5V, with anti-reverse protection slot (power
input pole, positive and negative reverse protection). With a power supply that exceeds the operating
voltage stroke, the receiver will burn out!
5.Do not attempt to charge LiFe batteries with a charger that is NOT designed for LiFe batteries, as
permanent damage to the battery and charger could result.
9.LiFe cells will not charge fully when too cold or show full charge.
