- Smart Contacts take two M18 packs that don’t match: different sizes, different charge.Works best with a matched pair of MilwaukeeMakitaDeWALT batteries (same size, both charged).
- Strap and S-hook in the box. Engel fridge hooks sold separately.



- Car power while you drive, battery power when you park. Add the $45 car cable. Doesn’t charge your batteries.
- Two batteries keep the fridge going once you’re parked up.
- Smart Contacts take two M18 packs that don’t match: different sizes, different charge.Works best with a matched pair of MilwaukeeMakitaDeWALT batteries (same size, both charged).

- Runs most portable 12V fridges, lights, pumps or a Starlink Mini.
- Smart LVD cuts power at 14.0V under load, before your MilwaukeeMakitaDeWALT pack over-discharges.Makita packs have protection built into the battery. It shuts off before the pack runs too low.

- Drains the fuller pack first until they’re level, then both together.
- The two packs are isolated, so neither feeds the other.

Why pay more than a cheap adapter?
Because what's inside decides whether your pack survives.
Quick answers
Will any of them charge my batteries?
No. They run your 12V gear off your tool batteries. With the Middle Man, the car takes over while you drive. Solar sharing (all three, with a Y-splitter) adds panel power. Neither charges your batteries.
Will it run my fridge and a Starlink Mini?
Running both together? Go the Middle Man: two batteries and more output than the single-battery kits. You'll need the Starlink Mini to Anderson cable (from $49).
What else might I need?
Every kit has an Anderson to cig socket lead. Optional: the $45 car cable (Middle Man), a Y-splitter for solar, Engel fridge hooks, the $45 Power Plate bracket. The car cable and solar don't charge your batteries.
How do I mount the Battle Station?
Four 3.5 mm holes on 90 mm and 60 mm centres. Screw, bolt or rivet it with your own fixings. See the mounting drawing.
