[QUOTE="Katabatic, post: 591985, member: 19153"] Just be aware that VRLA batteries require a specific type of charger: [url]http://www.power-plusbattery.com/CATALOGS/Technical%20Documents/VRLA%20Batteries%20ChargingMethods.pdf[/url] You'll need to make sure that any solar controller you buy can handle this type of battery. I use something like this for charging small VRLA's at home: [url]https://www.jaycar.com.au/12v-1a-sla-battery-charger/p/MB3619[/url] but that's not much use to you in the field, unless you have an inverter to drive it - I keep one of these in the glove box for those little 240V jobs: [url]https://www.ebay.com.au/itm/Portable-Car-Power-Inverter-100W-DC-12V-to-AC-220V-Charger-Converter-N5Y1/274450855948?hash=item3fe68bb80c:g:250AAOSwYXdfK7Ge&frcectupt=true[/url] The inverter/charger combo might be cheaper and more compact than mucking around with a solar panel and regulator - you can quickly top up the VRLA from the car battery, and you're not dependent on the weather for charging ability. Having the charger also means you can easily charge the battery when you get back home. [/QUOTE]
