I am using the ICE charger with team checkpoint balancer on SMC 5200 mah 7.4v. If i run the pack down to 6.2v prior to charging, it takes 75mins to recharge. The balancer charger combo works great. I am getting around 30 -35min run time on stock slash exc / motor combo. Have the VXL BL setup, but not going to install it just yet.

I know the ICE charger is a bit pricey, but its excellent. Used the engine break in feature for the TITAN as well. Checking to see how long that lasts... The memory feature is also brilliant, as I have various heli's, buggies and the slash. All battery charge rates are programmed and easy to select, then its just press a button and start wrenching!!
