Compact 12.8V LiFePO4 power

The Banshee 12V 7Ah lithium iron phosphate battery is built for users who need a lightweight, long-life power source. It suits outdoor enthusiasts, robotics hobbyists, and installers replacing sealed lead-acid units in alarm systems or solar lighting. The pack weighs 2.09 lbs and measures 5.94 x 2.56 x 3.94 inches, making it easy to carry or mount in tight spaces.

Cycle life and connection limits

Rated for 3000-plus charge cycles at 1C and 100% depth of discharge, the cell chemistry outlasts traditional SLA batteries by a wide margin. The integrated BMS manages cell balance and protection during each cycle. You may connect up to four units in series for higher voltage or four in parallel for greater capacity, but no larger arrays are supported by the manufacturer.

F2 terminals and rugged casing

The battery uses standard F2 terminals, so it drops into most existing 12V SLA trays without adapter cables. Its ABS housing resists vibration and handles the temperature swings common in camping, fish-finder, or e-scooter use. At 0.95 kg it delivers 89.6 Wh of energy while staying far lighter than the lead-acid equivalent it replaces.

Questions about this item

Should I pick the 7 Ah model or a larger capacity for my fish finder?

The Banshee battery is supplied as a single 7 Ah unit; if you need more runtime you can connect up to four of them in parallel to multiply capacity while keeping 12.8 V.

What does the 89.6 Wh rating mean when I run my camping lights?

At 12.8 V nominal the pack stores 89.6 Wh, so a 10 W LED light could run for roughly nine hours from a full charge.

The terminals are listed as F2 — what current can that handle?

F2 terminals accept standard ¼-inch spade connectors and are rated for the pack’s continuous discharge; the built-in BMS limits current to protect the cells.
