I came across these guys while looking for lithium batteries to replace my two old 120Ah AGM’s in our caravan. We decided to make the investment and purchase lithium batteries to replace our old AGM’s. After engaging with a number of suppliers and receiving conflicting information we found AMPTRON. What a great experience talking to these guys after a detailed Q&A session on the phone and a number of product options to consider. I was better equipped to make a decision on what to purchase for our off grid trip. One of the best presale services I have ever experienced, a big thanks to the team @ AMPTRON for your advice.
