So what do you guys run? What capacity, discharge and charge rate, and what manufacturer do you prefer? What vehicles do you run them in? Do you use different batteries for different applications and conditions? Or do you run the same packs? Just looking for opinions and discussions on different battery manufacturers. What's that worse experience you've had with LiPos or NiMH? The best? What's your oldest battery? Has it held up well? What chargers do you guys use? Does it work well? Get the job done? Feel free to discuss anything to do with batteries! We all run them (except for the Nitro girls and guys), so it's just something to talk about. We can learn from each others thoughts and opinions and make better choices when purchasing batteries. I'll start... I run these "Park N Power" packs that are exclusive to my area. A local guy puts these packs together. I don't think you can find them anywhere else, not entirely sure. Anyways they are great packs and they do pack a punch. I only run 3S in my Slash, and 2S in my SCX10. I've had these packs for about 7 months and they still run great. I've owned a 2S Venom battery before and I HAVE had ISSUES with it. I went to go charge it and both of the cells were defective. Yup. It only lasted about 2 months. I've tried out NiMH and they don't perform that well compared to LiPos. They are great to start with, but man, the voltage drops so quickly on those batts. Especially when using them in a high powered vehicle. Looking to purchase SMC batts soon. For charging purposes, I use my Venom Pro 2 Charger. It works great and gets the job done. It's got different modes and can charge both NiMH and LiPo.
