This is the EcoPower 7-Cell NiMH Hump Pack Battery with 4200mAh capacity. This battery is a great option for those looking to replace older NiMH packs or for those looking to upgrade from smaller 6-cell battery packs.

Because of the hump design found on this battery, length and width dimensions are standard for a NiMH stick pack, but the "hump" in the center may conflict with battery braces in some vehicles. Please consult your owners manual to ensure compatibility.
