  • Battery Pack2-pack
  • Battery TypeLithium
  • Up to 3000 charge cycles for long service life
  • Weighs only 2.09 lbs each for easy transport
  • 8 V nominal voltage matches 12 V systems
  • 7 Ah capacity delivers 89.6 Wh of energy
  • Compact 151 × 65 × 100 mm size fits tight spaces

Twin-pack lithium power

The Banshee 12V 14Ah twin pack supplies two 7Ah LiFePO4 batteries for users who need portable, long-life energy. Each unit weighs 2.09 lbs and measures 5.94 x 2.56 x 3.94 inches, making the pair easy to carry into the field. They suit outdoor enthusiasts, robotics hobbyists and anyone replacing heavier SLA blocks.

Cycle-life and connection limits

Rated for 3000-plus charge cycles at 1C and 100% depth of discharge, the chemistry outlasts traditional lead-acid by a wide margin. You may link up to four packs in parallel or four in series, but no larger arrays are supported. The F2 terminals accept standard quick-connect leads without adapters.

Capacity headroom

Together the pair stores 89.6 Wh per battery at a nominal 12.8 V, delivering twice the usable capacity of an equivalent SLA at 60% of the weight. The 7 Ah rating comfortably runs fish finders, solar lights or alarm panels for extended periods. High-draw loads such as e-scooter motors will deplete the reserve faster than low-drain devices.

Questions about this item

Should I buy the twin pack or a single 12V 7Ah Banshee battery?

The listing is a twin pack containing two 12.8V 7Ah LiFePO4 units. Each battery delivers 89.6Wh and weighs 2.09 lbs. Buying the pair gives you 14Ah total capacity and allows up to four units in parallel or series for larger systems.

What does the 7Ah rating mean when I put one of these batteries in my fish finder?

At the nominal 12.8V, each battery stores 89.6Wh. A 7Ah rating means it can supply 7 amps for one hour, or 1 amp for roughly seven hours, before reaching full depth of discharge. Actual run-time depends on your device's current draw.

The terminals are listed as F2 — what does that cap in practice?

F2 terminals accept standard ¼-inch quick-disconnect spade connectors. The battery management system supports continuous charge and discharge at 1C, so the practical current limit is about 7 amps per battery; wiring and connector gauge should be chosen accordingly.
