BatteryJack inc. Banshee 12V 7Ah LiFePO4 Standard Battery for JL Marine Power-Pole Anchor

Compact LiFePO4 power for marine anchors

The Banshee 12V 7Ah lithium iron phosphate battery replaces sealed lead-acid units in JL Marine Power-Pole anchors. It delivers 12.8V nominal voltage and 89.6Wh energy in a 151 × 65 × 100 mm case weighing 0.95 kg. The pack suits anglers and boaters who need reliable starting power with minimal weight penalty.

Sustained output over repeated cycles

Rated for 3000+ charge-discharge cycles at 1C and 100% depth of discharge, the cell chemistry maintains capacity far longer than lead-acid equivalents. Up to four units can be wired in series or parallel to scale voltage or runtime for extended days on the water. The 7Ah rating supports consistent current draw without the voltage sag typical of aged SLA packs.

Thermal stability and efficient charging

LiFePO4 chemistry operates safely across extreme temperatures encountered in marine environments. The 2.09 lb pack accepts fast charge rates while generating minimal heat, and the F2 terminals ensure secure low-resistance connections. No active cooling is required, keeping the installation silent and preserving the anchor’s stealth advantage.
