This is our new Mudboss Version 3 using our new HCL-RS formulation.   Results are an increase in the voltage curve with a 10-15gr weight saving. IR is a bit lower then the V2 model it replaces. We believe this to be the best pack for the Mudboss class which inlcudes racers racing in the open pack Mudboss classes.   You can check out the comparison between the V2 vs V3 pack at the bottom of this page.

- 10AWG wires soldered straight to the tabs for lowest possible resistance.

Size:                          25mm x 47mm x 139mm Hardcase

Weight:                      337gr        

Wire size:                  10AWG

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

Using the WMH Racing Battery Wizard below is the IR and voltage drop test at 200A simulation load. You can see  voltage drop of the V2 Mudboss pack versus our new RS-V3 Mudboss pack.  Please note there is no heating of the pack.  Pack is charged at 12A from storage voltage and tested at 22C/72F.   Second set of pictures is the voltage curve with the seconds it takes to get to 8v , 7.90V and 7.80V.
