A Main Hobbies Announces ProTek R/C “Supreme Power” 50C Hard Case Li-Poly Car Battery Packs (ROAR Approved)
Chico, California, August 4, 2010 – A Main Hobbies today announced a new line of ProTek R/C brand Lithium Polymer hard case power battery packs for radio controlled cars, with true 50C constant discharge rate. Lithium Polymer batteries produce longer run-time with less weight than traditional NiMH cells and have no memory effect! They can be charged hours or days ahead of time and may be used and recharged limitless times per day.
These packs include bullet connectors for charging and balancing, or a balance charge lead with a Deans style T-plug installed. The balance adapter included is an Align/E-Flite style XH balance connector. These battery packs are built using a hard plastic pack that is required for use at ROAR sanctioned tracks and events. The packs are available in multiple configurations from 1S for 1/12th scale pan cars to large 4S packs for 1/8th electric off-road buggies and truggies.
Note: Some vehicles may require some re-balancing if the light weight of these batteries cause some handling changes. To get the vehicle to balance correctly, add some weight to the battery side of the vehicle.
The batteries will sell with a street price ranging from $59.99 to $199.99. But don’t be fooled by the low price! These batteries perform as good as or better than the most popular name brand batteries on the market today.
2C Maximum Charge Rate!
This battery pack is designed to be safely charged at 2C, twice the normal 1C charge rate required for most Li-Poly battery packs. With a 2C charge rate, you can get these battery packs fully charged in only slightly more than half the time it will take to complete a 1C charge.
CRASH Protection Guarantee!
This battery pack is covered by the ProTek R/C manufacturer “Crash Protection Guarantee”! If you crash your vehicle badly enough to damage the battery pack, you can send the damaged battery pack back to ProTek R/C and purchase a replacement battery for 50% off the regular sale price!
