Chico, California, October 18, 2007 A Main Hobbies today announced a ProTek R/C brand Lithium Polymer 2-cell 4000mAh 20C power pack. 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 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 weighing only 200g (7.1oz) when compared to regular NiMH race packs which weigh over 400g (14oz) for the same capacity! 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 a lot lower internal resistance. This leads to better top speeds and improved ‘punch’ off the line when compared to NiMH batteries. These batteries will also make excellent car or truck starter box batteries! You can significantly reduce the weight of your starter box, as two of these batteries will weigh less than half than two 4000mAH NiMH packs (400g versus 800g). This will make your starter box almost 1 pound lighter! Not to mention they will have increased voltage and punch, making it easier to start a tight engine. 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. You may also need to use some foam material to keep the battery firmly in place in your vehicle so it cannot come out while you are driving. The batteries will retail for $73.99 and sell with a street price of $59.99. But dont be fooled by the low price! These batteries will hold their own against the most popular name brand batteries on the market today. 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! Specifications: Type: Lithium Polymer Capacity: 4000 mAh Voltage: 7.4V nominal Connector Type: None (16 GA Wire) Balancer Type: Align/E-Flite compatible Number of Cells: 2 Weight: 200g Configuration: 2S1P Dimensions (WxLxH): 40 x 134 x 15mm Maximum Continuous Discharge : 20C (80A) Maximum Burst Discharge : 30C (120A) https://www.amainhobbies.com
