Purpose & fit

This DUSLAN 12.8 V LiFePO4 pack delivers 3300 mAh (42 Wh) in a four-cell 26650 layout. It suits builders who need a lightweight, long-cycle 12 V source for portable instruments, solar storage or UPS backup where safety and thermal stability matter. Buyers needing higher capacity or faster charge rates should look elsewhere.

Installation & pitfalls

The pack ships with 6-inch 18 AWG open-end leads for direct soldering or connector crimping. No holder or mounting hardware is included, so mechanical fixing is the installer's responsibility. A 7 A polyswitch and on-board PCB limit discharge and guard against over-charge above 15.6 V, over-discharge and short circuits, but the 1.5 A recommended charge current must be observed to avoid tripping protection.

Capacity & headroom

At 3300 mAh the pack runs modest loads such as sensors, small radios or LED lighting for many hours; continuous draw is capped at 7 A by the protection circuit. Cycle life exceeds 1000 cycles at 80 % capacity retention (0.2 C, IEC). Peak voltage reaches 14.6 V and cut-off sits at 10 V, so equipment must tolerate this window.

Questions about this item

How do I verify the pack is working correctly after wiring it up?

Measure the open-circuit voltage with a multimeter; a healthy pack reads near 12.8 V and should not exceed 14.6 V when fully charged or drop below 10 V under load.

What comes in the box and what must I source separately?

The pack arrives pre-wired with 6-inch 18 AWG open-end leads for charging and discharging; you will need a compatible LiFePO4 charger and any connectors or enclosures your project requires.

Which capacity version should I choose for my application?

This model is offered only as a 3300 mAh (42 Wh) pack built from four 26650 cells; select it when you need roughly 42 Wh at 12.8 V with a 7 A discharge limit.
