Sometimes, for serious campers and caravanners, the whole power thing can just seem too complicated! You’ve got starter batteries and service batteries to keep charged – even when you’re on the road. You’ve got essential devices like emergency lights – and in some instances even life-or-death appliances like sleep apnoea machines – that need 100% reliable power. Of course, you want to keep your power-hungry fridge running, and those of you who like to escape with all the comforts of home will need your inverter to be in top shape so you can watch TV or surf the net. How can you get the most out of your power system with rapid battery charging no matter where you are, optimal conditioning and charging to prolong the lifespan of your batteries and maximum power output for all your on-the-road needs – so you can stop stressing about power and just enjoy the good times?

Bainbridge Technologies and CTEK make it simple, with the ‘Dynamic Duo’: the CTEK D250S Dual DC-DC Smart Charger integrated with the CTEK SMARTPASS Complete Power Management Unit. This remarkable combination gives your batteries a faster charge, a fuller charge, more power and a longer lifespan; it saves you hassle, time and money! Best of all, it’s as easy as 1,2,3!

1. CTEK D250S Dual DC-DC Smart Charger

With fuss-free DIY installation, the CTEK D250S Dual charges, maintains and conditions your start and service batteries with alternator power while you’re travelling and/or solar power when you’re stopped.

2. CTEK SMARTPASS Complete Power Management Unit

Smart, simple, multi-featured, the CTEK SMARTPASS manages and optimally distributes your alternator, solar and even wind power. It directs regulated energy where it’s needed; it boosts alternator output; and it minimises charge time.

3. The integrated SMARTPASS / D250S Dual System

Putting these 2 units together is the critical step in achieving quick charging and optimal battery reliability – so you can take off in your supped-up camper trailer or caravan and relax, knowing you’ll have all the power you need when you need it!

As an integrated system, the SMARTPASS manages the energy transfer through the D250S Dual which then converts and produces the optimal voltage of 14.4V – even if your alternator only produces 14V or less.

Here’s how the ‘Dynamic Duo’ work together:

The D250S Dual, which can charge up to 20A, is a ‘buck and boost’ charger which can reduce volts if the voltage is too high and boost the volts if the voltage is too low. In an integrated system, the SMARTPASS acts as a voltage controlled relay, initially passing high charge currents through to get your service battery charged up quickly. When your service battery voltage equals your starter battery voltage (less than 20A), charging automatically switches back to the more versatile D250S Dual.

The SMARTPASS shares the charge current between the service battery and electrical appliances. In an integrated system, it powers non-critical appliances while the service battery charges, so charging is faster and more efficient. Without the SMARTPASS, batteries being drained by appliances like power-hungry fridges might never fully charge!

The SMARTPASS senses when voltage on the service battery is low and protects the operation of critical appliances – like emergency lights, navigation and radio – by disconnecting non-essential devices until there is sufficient power to re-connect.
The ‘Dynamic Duo’ does it!

Together, the D250S Dual and the SMARTPASS solve the problems of keeping everything running smoothly, so you can relax and enjoy the good times: The ‘Dynamic Duo’ gives you:
