The Expion360 12V 80Ah is a Group 24 deep-cycle LiFePO4 battery built for RVs, marine use and off-grid setups. It uses stainless-steel-encased 26650 cylindrical cells, oversized terminal pads and a case that mounts in any orientation. At 24 lbs it weighs roughly half a comparable lead-acid Group 24. Its best new price is $687.65 at Walmart as of November 5, 2026, with 4 stores listing it new.

Pros
  • About 24 lbs, far lighter than a lead-acid Group 24
  • LiFePO4 chemistry holds voltage under load and tolerates deep discharge
  • Group 24 footprint drops into many existing trays
  • 360-degree mounting works in tight compartments
  • UL1973 compliant with UL1642 recognized cells
  • Oversized terminal pads simplify heavy-gauge wiring
Cons
  • 80Ah is modest for high-draw trolling motors or big inverters
  • Premium price versus many 100Ah LiFePO4 batteries
  • Charging needs a lithium-compatible profile, not a plain lead-acid charger
  • Cold-weather charging below freezing requires care
  • Spec sheet lists 36V series wiring, which needs a compatible charger setup

Questions and answers

Is this a true Group 24 drop-in?
Yes. It measures 10.24 x 6.81 x 8.59 inches, close to a standard Group 24 case, and mounts in any orientation.
Can I run it in series for a 36V trolling motor?
The listing describes series connection for 36V trolling motor use, but you need a 36V lithium-compatible charger and matched batteries.

Yes. Use a charger with a LiFePO4 profile; a standard lead-acid charger will not charge it fully or safely.

It gives about 20% less runtime. Choose it when Group 24 fit and weight matter more than maximum capacity.

At $687.65 at Walmart as of November 5, 2026, it is priced above many 100Ah lithium batteries. The case is the weight savings, UL listing and flexible mounting.
