This is a Li-Poly 2100mAh receiver battery pack from ProTek R/C. This
super light weight Li-Poly battery is designed to power the electronics
of 1/10th & 1/8th scale gas powered race cars. Overall weight of
your race car will be significantly reduced over the use of typical
NiMh receiver packs. The battery voltage to your receiver and servos
will remain constant throughout the race with the use of a voltage
regulator (required). A constant voltage for your servos will ensure
consistent performance at the start and end of your race compared
to typical NiMH receiver battery packs.
Perfect battery for the Airtronics M11X radio!
This battery is also the perfect transmitter battery for the Airtronics M11X transmitter, which requires a 2S Li-Poly battery for operation.
Runtime:
Don’t
be thrown off by the capacity rating of Li-Poly battery packs, as you
will get awesome runtime out this pack! Unlike NiMH battery packs,
Li-Poly battery packs do not lose voltage as quickly over time and can
handle higher current draw than typical NiMH battery packs. Given that
Li-Poly battery packs provide a higher nominal voltage (7.4V nominal),
the actual capacity of the battery pack when compared to a typical NiMH
battery pack (6.0V nominal) is about 30% more than the rated value (so
this pack would be about the same as a 2700mAh NiMH pack in total
capacity). Also with the use of a voltage regulator, Li-Poly battery
packs will produce the same voltage to your receiver and servos at the
end of the pack as it does at the start. This means the useable
capacity of the battery pack is significantly more than typical NiMH
battery packs, because most NiMH battery packs will produce
significantly less than the 6.0V nominal voltage once they get below
half capacity (ie: your servos will be a lot more sluggish if your
typical NiMH battery pack is below half capacity).
Why must Li-Poly receiver packs be used with a voltage regulator?
Although
the Li-Poly battery pack’s nominal voltage is 7.4V, when it is fully
charged the voltage output is 8.4V. The 8.4V output exceeds the safety
level of most receivers and servos on the market, so you must use a
voltage regulator with these Li-Poly receiver packs to decrease the
voltage to safe levels that your receiver and servos can accept.
IMPORTANT:
1) You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
2) You must not over discharge the Li-Poly battery pack.
3) Read the instructions carefully before operating this battery.
