Dr_GN 16 Posted May 18, 2020 All, I started running my '84 Frog during lockdown, and have upgraded it with a 3300 NiMh battery, ESC and ball races throughout. IIRC I was getting 20 mins run time back in the day from a 1200 mAH NiCd hump pack (others have said that was hugely rose tinted, and it was more like 5-10 mins). I'm absoultely sure it was longer than 5 minutes, but still... I've timed the runs, and I'm getting about 14 minutes tops. Even if I was down at only 10 mins in '84, I should be at 27 minutes just on increased capacity alone, never mind having eliminated the resistors and nylon wheel/drive bushes. The battery has now been charged and run about 5 times. Any ideas? Cheers. Share this post Link to post Share on other sites

A-Baum 352 Posted May 25, 2020 Something odd is going on as I run a 3300 pack on a rere Blackfoot and I get 45+ minutes. Bad battery or charger perhaps? 1 Share this post Link to post Share on other sites

catman79 346 Posted May 25, 2020 Sounds like the battery, some cheaper Chinese batteries branded As say 3000 mah are in fact no where near that. what battery do you have? 1 Share this post Link to post Share on other sites
