Had my Slash for 2 months now running on NiMh. Good fun, was still able to break parts... I was happy. Now... I am on 2S LiPo's!! Holy Crap! What a difference!! WHY I didn't do that from the get go I'll never know! Way more punch from a dead stop... Goes through the snow like nobody's business... Even notice more top speed... I can do *******' wheelies!!!
Moral to my story... Any of you out there researching to decide if you want to go Lipo, research no more. Make the investment and GO. Don't get nervous about the hazards or the cost. Make the investment, treat the batteries properly, buy quality stuff and you will never, NEVER regret it! The increase in cost isn't that much and you get way more value!!!
I wish I had done the same 2 months ago. Now I have 2 40 NiMh chargers and 6 packs that will never see the light of day.
