⚠️ Important: Upgrading to Modern Batteries
This is a NiCd battery designed for older brushed motor systems. If you're upgrading your vehicle to modern LiPo batteries, you must replace your electronic speed controller (ESC) with one that includes Low Voltage Cutoff (LVC) protection. LiPo batteries require LVC to prevent over-discharge, which can cause permanent damage and safety hazards.
The HR72 physically fits in the same space as modern NiMH and 2S LiPo hard-case packs, but the chemistries are not interchangeable without proper equipment upgrades.
Cross Reference & Compatibility
Customer Reviews
NiCd battery performed as it should in a classic Team Associated RC10 remote control car from the 1980’s.. I am pleased with the product and the fact that I was able to get the old car working again. I did not want to upgrade to newer technology and simply get the classic working again.
