The Dolgin Engineering TC400-DSLR-C Four Position Battery Charger with TDM simultaneously charges 4 Canon LP-E6 battery packs. It will charge batteries in approximately 3.5 hours when all 4 channels are filled. Additionally, each battery bay is independent, meaning that batteries can be added and removed at any time.
The TDM model features a Test Discharge Module which cycles the battery through a charge-discharge-charge cycle to determine true capacity. An LCD display provides information on the status of each battery. It also provides the charging information in volts, Ah, and percent of charge. This charger is compatible worldwide with a 100-240VAC power supply.
