This is the ProTek R/C 4S 2100mAh Lithium Polymer battery pack. This
pack has no connectors so you can attach your connectors of choice, and
comes with a 5-pin Align/E-Flite style balance connector. This powerful
Li-Polymer battery pack has a powerful punch with 14.8V and 2100mAh run
time. This pack is sure to push your electric helicopter or plane to
literally new heights!
Unlike most other Lithium Polymer batteries, these batteries can be charged at up to 2 times the rated current, or 2C! If your charger is capable, you can charge these batteries at up 4.2A!
This battery will also make an excellent starter box battery for R/C Cars! You can
significantly reduce the weight of your starter box, as one of these
batteries will weigh less than one third of two 3600mAH NiMH packs (220g
vs 802g). This will make your starter box almost 1.3 pounds lighter! Not
to mention they will have increased voltage and punch, making it easier
to start a tight engine.
CRASH Protection Guarantee!
This battery pack is
covered by the ProTek R/C manufacturer "Crash Protection Guarantee"! If
you crash your vehicle, helicopter or airplane badly enough to damage
the battery pack, you can send the damaged battery pack back to A Main
Hobbies and purchase a replacement battery for 50% off the regular sale
price!

2) You must not over discharge the Li-Poly battery pack.
3) Read the instructions carefully before operating this battery.
NOTE:
When using high energy Li-Polymer Batteries, please do not
over-discharge or over-charge batteries as this will result in over
heated batteries. Discharging capacity can't exceed 80% of the max
capacity of the pack after full charging to ensure a good cycle
performance. It is recommended to fully charge a brand new battery
before using and only discharge the battery 50% for first 5 cycles.
Always monitor race time and/or set a low voltage warning on ESC (End
voltage cannot be lower than 3.2v per cell) Do not use the battery that
has too low a voltage.
Do not expose batteries to sunshine or store/charge
batteries at the temperature above 35°C or in a closed car. The high
temperature environment could cause damage to the pack or make it
burst. If the battery becomes hot while fast charging, high current
discharging or racing, do not charge the battery until it has cooled
completely. Wait about 20 mins, then inspect prior to recharging.
