This B&H Kit packages the Dolgin Engineering TC40-SON Four-Position Charger with four Sony NP-F970 L-Series batteries. This combo provides a quick-charging solution for powering any NP-F970–compatible camera. The TC40-SON charger features simultaneous charging for up to four batteries with an approximate 4.5-hour charging time. This charger is also compatible with NP-F975, NP-F770, and third-party models. It has front-panel LED status lights, and it accepts 100-240 VAC power as well as 12 VDC power (via an optional adapter).
For better battery management while shooting, the Sony NP-F970 battery's Info-Lithium system displays remaining battery time in minutes in the EVF and on the LCD of compatible cameras. These 7.2V lithium-ion batteries will not develop a memory and can last for up to 12 hours on a single charge.
Dolgin Engineering TC40 Four-Position Simultaneous Battery Charger for Sony L-Series
The TC40-SON from Dolgin Engineering features integrated battery plates that support Sony and third-party NP-F970, NP-F770, NP-F975 batteries. These batteries are used with Sony's HD1000U, Z5U, Z7U, MC2000U, NX5U, HDRFX7, and FS700R cameras.
The TC40 has semi-independent channels and provides Dynamic Power Management (DPM) when charging four batteries. This means that it allocates more power to the battery that needs it the most first. Once battery levels are equal it charges all batteries simultaneously with equal power distribution. The result is that all batteries will be ready at the same time. Based on a capacity of 5600mAh, the TC40 delivers a complete charge in approximately 4.5 hours for four batteries or when you charge a single battery. With the battery plates built in, the battery contacts are ensured to remain more intact.
Charge status is displayed per battery by indicator lights on the front panel. The TC40 comes with a U.S. power cord and supports worldwide power input via optional plug adapters, as well as 12 VDC car lighter power via an optional adapter (model # DE_CAR_12).
Sony NP-F970 L-Series Info-Lithium Battery Pack (6300mAh)
Small and lightweight, Sony's NP-F970 Info-Lithium Battery Pack (6300mAh) provides the advantages of lithium-ion, meaning it can be charged or discharged at anytime without developing memory effect. This means the battery never loses its ability to hold a full charge. The NP-F970 displays remaining battery time on the LCD as well as in the viewfinder by continuously communicating with the camcorder. The battery lasts for up to 12 hours on a single full charge. Sony's Info-Lithium battery packs have a built-in micro processor that accurately calculates remaining battery life in minutes.
