Having a correctly installed Dc-to-Dc charging system in either your caravan or vehicle will guarantee the charging system is kept under a managed limit.
As lithium becomes more and more popular among the 4wd and caravan industry, people are realising the added benefits of light weight, more energy dense lithium battery systems. Keeping these cells and BMS happy with regulated charge will ensure the life expectancy is achieved. No BMS disconnects and 100% state of charge is reached. A key feature to note here is alternator loading. Most modern factory fitted alternators produce their best power at 1500-2000 rpm. This is cruising RPM for most vehicles. The cooling of the alternator is done by an internal fan so as it heats up under load (i.e., a big lithium battery running from it with no regulator/ Dc charger) the stress can derate the output and failure is imminent. I have seen this on many occasions and now even more so with the onset of lithium. Running a controlled charge rate based on both your alternators output and the systems battery bank will keep things running cool, efficient and you won’t have a failed alternator or flat starter battery.
Bigger is not always better here.
An example here would be two Dc-to-Dc chargers running from a factory alternator. If one is a 25amp Dc charger and the other a 50amp Dc charger the actual load input before the Dc charger is higher. Roughly 30 amps for the 25amp Dc charger and up to 60 amps on the 50amp Dc charger. That’s 90 amps right there under bulk charge conditions. And, the bigger the battery bank the longer it will take to charge so you need to design the system accordingly.
We specialise in the field of Dc-to-Dc charging and guarantee you get the charge rates from the system we design.

Great service and he knows his job
November 25, 2018We didn’t mind driving up from Melbourne and waiting for over 3 months for a booking to get some of Matt’s 12volt expertise in upgrading our lithium power... read more needs, SatKing Pro satellite and Cel-fi Signal booster and Sirocco fans installation to the bunk as well as additional solar panels on our JB Scorpion Sting. We’d rate Matt’s knowledge to that of an ‘Expert’ in his field. Matt and his apprentice Riley have a lovely disposition, great work ethic and utmost regard for the client’s gear. They covered all surfaces before working on them, even put cardboard on the floor inside the van, taking great care not to scratch or damage the caravan. Even their ladder has a soft protective foam to avoid damage to the van when leaning against it. They arrived on time, worked diligently, cleaned up after themselves and even went the extra mile to repair / amend some rather ordinary factory work on the caravan which was well outside the scope of their engagement with us. We found the price to be reasonable and the quality of their work is unmatched. After sales support is amazing with Matt. He is not shy to answer his phone and attended to your queries. Will be using and recommend Matt’s service in the future without the slightest hesitation. Thank you Matt and Riley. We love the work you have done. We can now free camp for so much longer, have phone reception with Cel-fi booster to work remotely and the SatKing to enjoy TV in the middle of no where and kids can stay cool in WA and the NT with their new fans Cheers Daniel, Preeti and kids!

He also suggested an alternative to the quoted scope of work which saved significant cost without compromising targeted performance. I particularly appreciated his preparedness to reschedule a subsequent visit at no cost to explain & handover the upgraded system. I can’t recommend Matt & his work highly enough.
