Four-Pack Lithium-Ion Battery Kit

The Kastar DLI-301 kit supplies four 3.7V 1400mAh lithium-ion batteries plus a compact AC wall charger. Each cell stores 5.18 Wh of energy. The package targets owners of the Zoom Q4 or Q4n Handy Video Recorder who need reliable spare power for extended shoots. It also fits devices that accept Zoom BT-02 or 247-9036 cells.

Steady Charging Across Global Voltages

The charger accepts 100 to 240 V AC at 50 or 60 Hz and delivers a constant 4.2 V DC at 600 mA. This regulated output maintains a stable current through the full charge cycle rather than tapering off after a quick burst. A red LED shows active charging; green signals standby or full charge.

Foldable Plug Simplifies Travel Setup

The wall adapter uses a foldable flat pin that tucks away for packing and snaps out for any standard outlet. No cables or separate power bricks are required. The only common issue is forgetting to seat each battery fully in the slots, which leaves the LED on red longer than expected.

Questions about this item

How hot does the Kastar DLI-301 charger get when it runs all day?

The charger operates from AC 100~240V 50~60Hz input and delivers DC 4.2V 600mA output, so heat stays low during continuous use.

What must I already own for these four batteries to work in my camera?

You need a camera that accepts the Benq DLI-301 form factor, such as the Benq G1, G2, G2F, EX1 or EX2 models listed.

Will these 1400mAh batteries hold charge as well in my older Zoom Q4 recorder as the original cells did?

Yes, they match the 3.7V 1400mAh spec and are listed as direct replacements for Zoom BT-02 and 247-9036 batteries used in the Q4 and Q4n.
