Watson Pro L-Train 6-Bay NP-F Battery Charger

In a highly compact design from Watson Pro, the L-Train 6-Bay NP-F Battery Charger offers six L-series battery bays, a charge current selector for each bay, and two 12V/3A DC ports that work as both inputs and outputs. The L-Train is a simultaneous charger designed for environments where fully charged batteries are in constant high demand, settings such as photo/video studios and rental houses.

In addition to running on AC power from a wall outlet, the charger can be powered via the 12V DC ports using a DC power source, such as a V-mount or Gold mount battery, or a car lighter, using separately available adapter cables. As outputs, the DC ports let you charge or power various devices such as cameras, flashes, and lights (when there are no L-series batteries being charged).

1.2A/2A Charge Current Selection
Next to each battery bay is a current selector switch that lets you toggle between 1.2A standard charging and 2A fast charging. The L-Train charges up to six L-series batteries simultaneously while the charge current is selectable individually for each battery. At 2A, a battery is charged in about half the time as at 1.2A.
12V DC Ports
The DC ports can function as either power inputs or outputs. As inputs, if you are away from mains power, you can connect a DC power source, such as a 12V vehicle connection using a separately available adapter cable, to charge the batteries. When the DC ports are used as outputs, the charger will convert incoming AC power to 12V DC, which will be output via both barrel jacks when no batteries are connected.
Battery/Current Status Indicators
An array of LED indicators next to each battery bay provide an approximate percentage of how much each battery has been charged. A separate LED indicator next to each bay stays lit when you have 2A rapid charging selected for that bay. This way, you can tell with just a quick glance what current you're charging at.
Temperature Maintenance
The L-Train uses temperature-regulating circuitry and an integrated cooling fan to ensure uninterrupted operation without overheating. The charger maintains a constant cool temperature so that you can use all six bays without concern of overheating.
Compact and Lightweight Design
The charger has a compact form and takes up minimal desk or counter space, and it won't weigh down or take up much room in a gear bag or grip case.
Compatible Batteries
Compatible NP-F L-series batteries include the NP-F550, NP-F570, NP-F750, NP-F770, NP-F960, and NP-F970.

Does using the quick charge feature not top the batteries off all the way? If not in a hurry, why use the quick charge at all?
Asked by: Hugh
The 2A quick charge of the Watson Pro L-Train 6-Bay NP-F Battery Charger would charge each of the six connected batteries completely. Charging of all six bays is simultaneous.

What are the downsides to using the quick charge feature as opposed to the slow charge feature?
Asked by: Hugh
Batteries have a life cycle and you could be cutting into that life cycle. Just note life cycles run in the hundreds, maybe thousands.

Is this compatible with the DJI Focus Pro Hand Unit?
Asked by: Matthew
The batteries with the Watson NP-F770 Kit with 2 Batteries and DuoVolt Smart Charger are too large for the DJI Focus Pro Hand Unit. For the hand unit, NP-F550 size batteries need to be used, like the Watson NP-F550 Kit with 2 Batteries and DuoVolt Smart Charger, B&H # WANPF550DCK.
