Description ATG Lithium Batteries are designed here in Perth, Australia. We hold stock in our Mandurah warehouse and where possible, same day shipping will apply. The ATG 300AH lithium battery is the biggest battery we sell. Its a monster of a battery, with the equivalent of 5x 100AH AGM batteries. This battery is recommended for caravan owners who are planning to hardwire 240v inverters for off grid A/C and plan to run A/C for a few hours at a time. They come with a large 250A BMS, which gives you peace of mind when running multiple 240v appliances off grid at once, it will not cut out. Here at Mandurah Lithium Upgrades, we prefer to fit a single ATG 300AH lithium battery for anyone who wants off grid 240v power and who free camp more than 7 days at a time. These batteries are designed for large sized electrical loads, like 2000w-3000w inverters and for those who want the peace of mind of having enough power for your road trip. When upgrading caravans to lithium batteries, if you have a 2 way compressor fridge, want off grid 240v appliances and want to do more than 7 days free camping off grid, this is the perfect battery for you. A single 12v fridge running off this battery will see about 15 days use before going flat. Here at Mandurah Lithium Upgrades, we supply and install these ATG 300AH Lithium Batteries every week and have never had an issue. They are the best value for money lithium battery in Australia and that's why we use and recommend them. **All our ATG lithium batteries come with 2x tie down straps and brackets and 2x extra long 20mm bolts** Now with Bluetooth!
