This Curtech regulator has some new features which will not only help maintain your battery charge but will also provide you with information so you are in control.
One of the features is the ability not to only show a battery voltage but this regulator will display 100% in the bar graph at the top of the screen when the battery is fully charged. It takes the guess work out of knowing if your battery is charged or not.
In addition to this, by a simple press of the voltage button the Amps which are being input to your battery will display. By pressing this button again, the accumulated Amps output to your battery will be displayed.
This Curtech solar controller will not only charge the standard AGM, Gel and Flood batteries it can also charge LiFePO4, LTO (Lithium Titanium Oxide) and Calcium Batteries.
It also is reverse polarity protected.

Ian White –
This is an excellent product which is also very easy to use. It was easy to install and works a treat. Solar Camping Australia is an excellent company to deal with and very helpful. I initially purchased all of my solar needs from them about seven years ago when I was rebuilding an old caravan we had and have purchased other products as I have needed them since. Steve has always been very helpful when I needed help and he won’t sell you anything you don’t need. Excellent company with excellent products with good prices and delivery. 5 stars all round.
