I was looking around at intelligent chargers and I ran into the NiteCore IntelliCharger. I had never heard of it so I did a little research. It seems to be the most versatile charger I've run across. They make an i2 and i4 version. The original i4 had issues but has been fixed in v2. It can charge practically everything, no spacers needed. Here's a review of the i4 V2 Review: SysMax/NiteCore Intellicharger i4 V2 Charger | BudgetLightForum.com and a short run down of features-
- Capable of charging multiple batteries/types simultaneously
- Each of the four battery slots monitors and charges independently
- Automatically identifies Li-ion, Ni-MH and Ni-Cd rechargeable batteries
- 3 Color LED displays charging progress for each battery
- Automatically detects battery status and selects the appropriate voltage and charge mode
