Compact 12V 100Ah LiFePO4 Battery for RVs, Campers and Trolling Motors

The Core Mini 12.8V 100Ah LiFePO4 battery gives you full size 100Ah performance in one of the smallest, lightest packages in its class. You get the same usable power as a bulky lead acid Group 27 or 31 battery, in a Group 22NF footprint that is easier to fit into teardrop trailers, compact RVs, van builds and small boats where every inch of storage matters.

Instead of wrestling heavy flooded batteries into cramped compartments, this 21.8 pound pack slips into tight spaces, runs clean and keeps delivering power trip after trip.


Same 100Ah Power, Less Weight and Less Space

Old school lead acid might say 100Ah on the sticker, but you only get a fraction of that if you want any sort of lifespan. The Core Mini uses EV grade LiFePO4 cells so you can actually use most of the rated capacity day after day.

Compared with a similar lead acid bank, you get:

  • 10 times the cycle life with 5000 cycles at 80 percent depth of discharge
  • A compact case at 9.02 x 5.43 x 8.39 inches
  • A much lighter battery at 21.8 pounds

For teardrop trailers, small campers and trolling motor setups, that is the difference between building around your battery box and simply dropping power into a space you already have.


Built For Rough Roads, Chop and Tight Compartments

This battery is designed to live where the fun happens. Metal cell spacers and a vibration resistant internal layout help protect the cells when you are bouncing down washboard roads or pushing through choppy water. The IP65 rated housing keeps out dust and spray, so it can live in front storage boxes, under benches and near transoms without needing a perfect environment.

Mounting is just as flexible. Multi orientation installation lets you rotate the battery to make the most of awkward compartments as long as you respect the space requirements. Plan for 2 to 4 inches of clearance above the battery and about 8 inches on the busbar side so cables and terminals are not fighting the walls.


Real Surge Power For High Demand Loads

Startup is where a lot of small batteries fall on their face. The Core Mini is rated for:

  • 100A continuous charge current
  • 100A continuous discharge current
  • 300A peak discharge for 5 seconds

That gives you enough surge for many inverters, trolling motors and high draw 12V appliances to spin up without drama when the system is sized correctly. It feels less like a toy battery and more like a compact power plant for serious small rigs.


Long Life Lithium That Just Keeps Going

At the heart of the pack are Grade A EV class LiFePO4 cells. They are rated for 5000 cycles at 80 percent depth of discharge to 80 percent end of life which translates into roughly ten years of steady use if you are cycling daily. Used seasonally for camping, RV trips or fishing weekends, it is the kind of battery you install and then forget about for a long time.

Operating ranges are tuned for real outdoor use:

  • Charge from 32 to 122°F (0 to 50°C)
  • Discharge from -4 to 140°F (-20 to 60°C)
  • Storage from -13 to 149°F (-25 to 65°C)

A built in low temperature charging cut off protects the cells if someone tries to charge when it is too cold, which is a common way cheaper lithium packs get damaged.


Compact Power For RVs, Campers and Trolling Motors

The footprint and weight are aimed squarely at compact rigs.

  • In teardrop trailers and small RVs it tucks into shallow cabinets, tongue boxes and under bed spaces that would never hold a big lead acid block.
  • On trolling motors and fishing setups it feeds the motor, fish finder and electronics from a single small case that is easier to move between boats or in and out of storage.

Because it is a true 12.8V LiFePO4 pack, voltage stays flatter under load compared with lead acid, so motors and electronics feel stronger for longer instead of sagging halfway through the day.


Ready For System Builds and Monitoring

You can build larger banks when you need more capacity or higher voltage. The Core Mini supports:

  • Series and parallel up to 4S4P

That means you can create 24V, 36V or 48V systems using matched packs, or stack multiple 12V units in parallel for more amp hours on the same system voltage.

It is also compatible with the Renogy 300A battery shunt so you can add remote monitoring and see real state of charge and current draw instead of guessing from voltage alone.
