A Main Hobbies Announces ProTek R/C 2S "Supreme Power" Li-Poly 40C Hard Case Battery Packs (7.4V/5000mAh) (ROAR Approved)
Chico, California, February 17, 2010 – A Main Hobbies today announced two new ProTek R/C brand Lithium Polymer 2-cell hard case power battery packs for radio controlled cars, with 5000mAh of capacity and a true 40C constant discharge rate. These batteries are ROAR approved and can be used at all racing events and tracks that require approved batteries.

With two versions available, part number PTK-LPH-5000-2S40-W includes an integrated balance charge lead with a Deans style T-plug installed. The balance adapter included is a 3-pin Align/E-Flite style XH balance connector. Part number PTK-LPH-5000-2S40-P includes heavy duty bullet connectors and a balance charge lead that you can solder onto the wire of your choice. The bullet connectors also feature side cut-outs for soldering on wires to fit in tight areas or in cars with low upper deck heights.

These battery packs are built using a hard plastic pack that is required for use at ROAR sanctioned tracks and events. The packs are thin enough to fit into all touring cars and off-road vehicles, and with the humps on the bottom will be secure in vehicles designed for side by side NiMH race packs.

These ProTek R/C battery packs can be used in any application where you need 6-cell NiMH stick or race packs, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. These packs are significantly lighter when compared to regular NiMH race packs. This makes the overall vehicle weight lighter for significantly improved acceleration. These batteries also have a nominal voltage of 7.4V compared to the 7.2V of regular NiMH batteries, and have dramatically reduced internal resistance. This leads to increased top speed and improved 'punch' off the line when compared to NiMH batteries.

The batteries will sell with a street price of $79.99, 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!
