A Main Hobbies Announces ProTek R/C 2S/5200mAh 35C Hard Case Li-Poly Saddle Car Battery Packs
Chico, California, May 1, 2009 – A Main Hobbies today announced a ProTek R/C brand Lithium Polymer 2-cell dual hard case power battery pack for radio controlled cars, with 5200mAh of capacity and a true 35C 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 have ultra T-style connectors attached, and come with a 4-pin Align/E-Flite style balance connector. These packs are ideal for use as saddle packs in electric RC cars. These battery packs are built using a hard plastic pack that is required for use at ROAR sanctioned tracks and events.

For mounting in a saddle pack configuration for cars like the Associated B44, we recommend you mount the battery flat to the chassis and use some kind of velcro or servo tape to secure them to the upper battery strap. This will stop the batteries from sliding out of the car sideways. To mount them flat you may need to remove the plastic battery holder from the chassis. If you have a strap permanently attached to the top of each battery, you can easily remove them from the vehicle for charging and simply put another battery in its place.

The batteries will sell with a street price of $119.99. 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!
