My son and I went to run our Son-Uva Digger a couple of days ago with a battery fresh off of our rapid charger. We got to the park to bash an AWESOME dirt mound that the city PARD had dumped there for some use and found that our truck was running like it was in the XL-5 Training Mode (or slower) and wouldn't even make it up the pile. I've double checked the ESC setting and put new batteries in the controller. I have noticed that despite being fully charged (twice now) after the truck makes even a short run, when I bring it back to me and check, the XL-5 LED is blinking red like the battery is low.
Question: Has the battery gone bad? I've had our truck stored in the garage over the last few weeks and I'm wondering if the Texas heat has damaged it in some way.
Question 2: Without going to a LiPo, what are the best replacement batteries you have found for the money? What performance enhancements, if any, have you seen. If I've got to spend the $$ I hope there's some sort of "fun factor" return on the investment.
Thanks for your help and input with this everyone!
