Battery and Charger
The Eraze comes complete with a motor battery and charger.
The Tx-R version requires a 600 mAh 7.4V LiPo battery and
LiPo Charger. The Eraze was designed for the Electrifl y ®
600 mAh 7.4V LiPo battery (GPMP0820). Other LiPo batteries
similar in size with the same voltage and capacity may also
work, but they may not fi t properly in the battery compartment
or have the same type of battery connector. In addition to a
battery, a LiPo battery charger is also required and there
are several that will work (depending on your budget and
requirements). A safe, economical charger is the ElectriFly
2S (2-cell/7.4V) LiPo Balancing Charger (GPMM3321). The
charger includes adapters to charge from a 110V wall outlet or
a 12V DC outlet from a car. The charger will take approximately
1-1/2 hours to fully charge the battery. Some pilots prefer to
have several batteries and charge them faster so they can
fl y more. For charging up to four batteries faster at the same
time, the Great Planes PolyCharge4
™ DC-powered LiPo
charger (GPMM3015) is recommended. But unlike the Smart
Charger, the PolyCharge4 does not have an internal LiPo cell
balancer which is a critical component in making sure your
LiPo batteries charge effi ciently and evenly. So, for each LiPo
battery you wish to charge simultaneously, one Great Planes
Equinox ™ LiPo Cell Balancer (GPMM3160) will also be required.
Finally, the PolyCharge4 does not have AC capability, so if
wall charging is a priority, a separate AC 12-Volt power source
must also be purchased separately. A suitable power supply
for the PolyCharge4 is the Great Planes 12V 12A DC power
supply (GPMP0901).
LITHIUM BATTERY HANDLING & USAGE
ONLY use a LiPo approved charger. NEVER use a NiCd/NiMH
peak charger to charge a LiPo battery.
NEVER charge in excess of 4.20V per cell.
ONLY charge through the “charge” lead. NEVER charge
through the “discharge” lead.
NEVER charge at currents greater than 1C unless the battery
is rated for a higher charge rate.
ALWAYS set the charger’s output volts to match the battery
volts.
ALWAYS charge in a fi reproof location.
NEVER trickle charge.
NEVER allow the battery temperature to exceed 150°F (65° C).
NEVER disassemble or modify the pack wiring in any way or
puncture the cells.
NEVER discharge below 2.5V per cell.
NEVER place the battery or charger on combustible materials
or leave it unattended during charge or discharge.
ALWAYS KEEP OUT OF THE REACH OF CHILDREN.
NEVER charge the battery in the plane.
ALWAYS remove the battery from the plane after a crash. Set
it aside in a safe location for at least 20 minutes. If the battery
is damaged in the crash it could catch fi re.
If the battery starts to swell, quickly move the battery to a safe
location, preferably outside. Place it in a bucket, covering the
battery with sand. Never use water to try and put out a LiPo fi re.
CHARGE THE BATTERY
The ElectriFly ® LiPo Battery Charger is great for simple balance
charging of 2-cell lithium-polymer batteries for small electric
models. Use it only to charge batteries within a capacity range
of 150 to 750mAh.
