The TC400-EX-TDM from Dolgin Engineering features integrated battery plates that support Sony and third-party BP-U30, BP-U60, and BP-U90 batteries. These batteries are used with Sony's PXW-FS7, PMW-EX1, PMW-EX3, PMW-100, PMW-200, and PMW-300 cameras.

The TC400-TDM has an LCD screen on the front panel that displays charge status in volts, amp hours, and percentage of charge that's estimated using a proprietary algorithm. The TC400-TDM is also designed with a built-in Test/Discharge Module that allows you to determine whether a battery is new or old, and whether it's on par with its label. The TDM feature cycles the battery (fully charges and discharges it) and then provides a report on its capacity.

The TC400-TDM has fully independent channels and provides simultaneous charging to all four batteries. This particular model will charge a single or up to four BP-U60 batteries in approximately 4 hours.

The charger comes with a U.S. power cord and supports worldwide power input via optional plug adapters.
