Review on ISDT D2 Mark 2 - Advanced Dual Channel Balance Charger & Discharger, 200W 12A2 AC Output, Suitable for 1-6S LiPo/Li-ion/LiFe/NiCd/NiMH/LiHV/PB Smart Batteries by Erin Abbott

Just installed and started this charger and I love it! Certainly faster than my old 5A charger. It charged my pair of 5000mAh Lipo 3S batteries in about 45 minutes, reducing typical charge time by over 50%. There's no instruction manual for this charger, just a quick start guide, so you'll have to fiddle with the controls and figure out the menus. This is intuitive after a few tries. A NOTICE. The balance plugs of your batteries can be connected directly to the front of the D2. The leftmost pin is negative and the connector expands depending on how many cells are in the battery. I think I'm new to chargers. Maybe it will help another inexperienced person.
