Good choice. Just keep an eye on the Nitecore, and if you have a multimeter, make sure you check your batteries voltage regularly. My D2 was awesome but about 3-4 months down the line or so it decided it was only going to charge my batteries to exactly 4.07 volts every time instead of 4.2. Still works rad for my AA rechargables I use in my mouse and Wiimotes so its still in business, but I wont put my 18650s in it anymore just in case.
