I bought some of their '200ah' batteries which are not spec described on their website. That is because they are not selling what they are advertising. The batteries are less than half the size that they should be, weigh about a third of what they should, and when I tested them, rated just under a third of the amp hours advertised. Absolute scam and I should've known with that price. Don't be fooled or greedy, this will burn you. Have reported them to ACCC and NSW Fair Trading but seems they are still operating. They trade as a few different names, Maverick butteries, GS, overstocked.
