The Carson 7.2 Volt 2700mAh Ni-MH Hump Back Battery Pack is designed for use with the re-released Tamiya Rough Rider and Buggy Champ. Manufacturer: CarsonModel: TA55059 / 608097 - 7.2 Volt 2700mAh Ni-MH Hump Back Battery Pack
“Recently found my son's old Tamiya Audi Quattro Rallye car in the loft; it must be more than 30 years old. The old battery was dead but with the new battery pack fitted and a bit of fiddling it's up and flying. The battery pack is a little shorter but stores a lot more energy giving a much longer run time. I'd forgotten what fun we'd had with this car and was reluctant to pass it on to my grandson.”
“I bought this for my Tamiya Sandscorcher, and it does the job as well as expected. Bear in mind that these hump packs don't fit in all Tamiya cars, as some cars are now designed to only hold the flat pack batteries, without the hump (Frog, Subaru brat, etc).”
