Our take on the Banshee Lithium Ion LiFePO4 Battery Kit 100Ah

The Banshee 100Ah LiFePO4 battery kit is a 12V-class lithium-iron-phosphate battery with dual marine posts, a built-in high-power BMS and a 1200 CCA rating, aimed at solar, RV, boat and off-grid power. Banshee rates it for 7,000+ cycles at 80% depth of discharge and says it weighs about 60% less than a comparable AGM or lead battery. It fits Group 31M trays. The best new price is $599.99 at eBay as of November 6, 2026, with two stores listing it new.

Pros
  • 7,000+ rated cycles at 80% depth of discharge
  • Built-in high-power BMS protects the cells
  • About 60% lighter than AGM or lead of similar capacity
  • Dual marine posts suit boat and RV wiring
  • Fits Group 31M trays, a common drop-in size
Cons
  • Listings mix 100Ah and 300Ah parallel figures, so check what the kit actually includes
  • 1200 CCA is a cranking claim that LiFePO4 is not the usual choice for
  • Needs a lithium-compatible charger and, in cold climates, low-temp cutoff
  • Only two stores list it new, so price competition is thin

Questions and answers

Is $599.99 a good price for this battery?
It is the best new price among the two stores listing it as of November 6, 2026. Comparable 100Ah LiFePO4 batteries with a built-in BMS often sell in the $250 to $500 range, so this sits at the higher end.
Is it 100Ah or 300Ah?
The battery is 100Ah. The 300Ah figure refers to running three in parallel, so a single unit gives 100Ah at its nominal voltage.
Can I use it to start an engine?
It carries a 1200 CCA rating, but LiFePO4 is usually chosen for deep-cycle house power. Check your engine's charging system and the BMS cranking limits before using it as a starting battery.
Will it fit my Group 31 battery tray?
Yes, it is listed as Group 31M compatible, the same footprint as many Group 31 AGM and lead batteries. Confirm the terminal layout matches your cables.
What charger do I need?
Use a charger with a lithium LiFePO4 profile. A lead-acid charger can stop short of full charge or overcharge it, and cold-weather charging needs a BMS with low-temperature cutoff.
What is in the kit?
The listing describes the battery with dual marine posts and a built-in BMS. Confirm with the seller whether cables, a charger or mounting hardware are included.
Where is the Banshee Lithium Ion LiFePO4 Battery Kit 100Ah cheapest?
At Big Time Battery, for $1,480.99, as of our latest check.
Where can I buy the Banshee Lithium Ion LiFePO4 Battery Kit 100Ah?
