A Main Hobbies Announces ProTek R/C 2100mAh 4S 20C Starter Box Battery

Chico, California, October 18, 2007 – A Main Hobbies today announced a ProTek R/C brand Lithium Polymer 4-cell 2100mAh 20C power pack. This lightweight Li-Poly 20C battery makes an excellent starter box battery for R/C Cars and Trucks! You can significantly reduce the weight of your starter box, as one of these batteries will weigh less than one third of two 3600mAH NiMH packs (220g vs 802g). This will make your starter box almost 1.3 pounds lighter! Not to mention they will have increased voltage and punch, making it easier to start a tight engine.

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.

You can find this product listed here:



  1. You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
  2. You must not over discharge the Li-Poly battery pack.
  3. Read the instructions carefully before operating this battery.
