Bought this neat-o Tamiya 1/10 RSR from Japan, batteries not included. It's from 2007, built by the Tamiya factory, was mint in sealed box. BUT, I can't get the specified 7.2V-500mAh battery pack anymore. Many other packs are available though and I am wondering if another 7.2V pack with a higher-amp capacity will work--provided I get one with the correct connector. For example, there is a Tamiya 7.2V-4200mAh on eBay. Will that work?
Yes, I checked for several hours on the 'net already but thought I'd ask the brain trust here before any more searching. TIA!
