Introducing the HCL-RS line of race packs (High Cycle Life - Race Series). These formulations are not the generic cells/packs you can get with different color stickers on them. These new formulations hold better voltage, sag less under loads seen in off and on road racing by optimizing the IR and mAh per cubic centimeter of the cells.  Scroll down the page to see a discharge graph.

True mAh +/- 5%:      4000mAh

Voltage:                     7.4V

C rate:                       150C

Size:                         18mm x 47mm x 96mm Hardcase 

Weight:                     163gr         

Wire size:              5mm inboard tubes with 2mm balance tube

Charge rate:          1C to 5C please note that a higher charge rate will put less mAh into the pack and will reduce cycle life
