How a Topo system works

A portable dual battery system keeps your fridge, lights and devices running without touching the vehicle’s starting battery. Here is what makes Topo’s different, and how to pick one.

Lives outside the engine bay

Topo systems install in the rear cargo area, a canopy, a ute tray or a battery box instead of under the bonnet, where heat shortens battery life.

Plug and play

Colour-coded, keyed leads halve the usual install and wiring cost. Most owners are set up in minutes, not hours.

Charges three ways at once

Vehicle, solar and mains can all feed the battery at the same time.

A third of the weight

Lithium iron phosphate weighs about a third of a lead-acid battery of the same capacity, with over 2,000 real-world charge cycles.

Protected inside

Built-in battery management guards against over-charge, over-discharge and short circuits, with magnetic circuit breakers on the outputs.

Moves with you

Lift it out of the car and into the boat, the camp kitchen or the caravan.
