|Chico, California, October 18, 2007 – A Main Hobbies today announced a new line of ProTek R/C brand Lithium Polymer transmitter packs designed to fit the Futaba, JR and Spektrum Airplane and Helicopter radios. This light weight Li-Poly transmitter battery is designed to reduce the overall weight of your transmitter. The overall weight of your transmitter will be significantly reduced over the use of typical NiMh receiver packs (97 grams compared to 225 grams for eight typical NiMH AA batteries!). Try to hold a pack of eight traditional AA size batteries and compare it with this Li-Poly Transmitter pack. The feeling is just awesome, and you get an incredible 5 to 6 hours of flight time!
You can find the JR/Spektrum compatible product listed here:
You can find the Futaba 7C/9C compatible product listed here:
Don’t be thrown off by the capacity rating of Li-Poly battery packs, as you will get amazing flight time out this pack! Given that Li-Poly battery packs provide a higher nominal voltage (11.1V nominal), the actual capacity of the battery pack when compared to a typical NiMH battery pack (9.6V nominal) is about 15% more than the rated value (so this pack would be about the same as a 1500mAh NiMH pack in total capacity).
How should the battery be inserted into the transmitter?
The foam provided in the package should be used to pad the transmitter battery area and stop the battery from moving around. It will fit into the transmitter battery housing with the battery sitting on it, and then, while pressing lightly on the battery, slide the cover over the battery.
- You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
- You must not over discharge the Li-Poly battery pack below 9.0V.
- Read the instructions carefully before operating this battery.
