Dual Battery Kits for your Offroad Adventure

The ultimate 12V 4WD and camping power management system

The new CTEK D250SA, 5-step charger, gives 4WDers the flexibility and ease of quickly charging up your service batteries from either traditional or smart alternators or from solar power. It will even give your starter battery a maintenance charge when your service batteries are fully charged.

Used independently CTEK’s D250SA and the SMARTPASS120 are superb, but combined, especially for service batteries larger than 100Ah, they become the ultimate power management system. Together these smart products can deliver up to 140A to your service batteries while you’re on the move.

This dynamic duo is the ultimate 140A power system that allows you to manage and control your power more reliably. So make sure CTEK is one of your mates when you head off on your next big adventure.

The 20A DC/DC Charger-D205SA features;

  •      A 5-step charger to quickly charge up your service batteries from either traditional or smart alternators or from solar power
  •      Smart alternator compatibility
  •      Special AGM function, featuring a selectable 14.7V for AGM batteries, as well as a 14.4V option for other batteries
  •      An advanced in-built Maximum Power Point Tracker (MPPT), maximising the power from your solar panels

Complete your offroad set up with the Baintech Dual Battery Kit


Let's face it: there aren't going to be any tow trucks or roadside assist where you're headed, off the beaten track. No one but hardcore 4WD adventurers will be going your way, and it will be a heck of hike home if you get stuck out there with a flat battery.

Don't risk it. Think about how you're going to get home NOW, before you go camping, winching, running your radio, lights and even your fridge out there in no-man's-land and ending up stranded far from civilisation with a dead battery.

A Baintech Dual Battery Kit is your foolproof, affordable and durable 'insurance policy' to ensure you get home safe and sound. It's smart – when your engine starts, the alternator starts charging your second battery and when your engine stops, it stops charging your second battery. It's powerful enough to meet any of your hardcore needs – 160 amp continuous operation. It's as tough as any of your adventures- IP68 waterproof, fully self contained and dust proof. and it's foolproof to DIY install - conveniently fits into your engine bay; includes cables, earth cable, voltage control relay, heat shrink, lugs and ties; just takes three simple wire connections and then it's ready to go.
