Hi Andy, the 22amp charger is more than capable of charging dual batteries. If the batteries are linked in parallel to charge them simply connect alligator clamp to the positive terminal of one battery and the negative terminal of the other battery.
“The product may be "Proudly Made in Australia" but getting tech questions answered here is impossible. My experience with their overseas call centre was not good. Tried the online "ticket" but it is too difficult. All of this does not inspire confidence.”
Hi Anthony, thank you for taking the time to leave a review. I am happy to answer any questions. On the product page we have the Ask a question button which goes directly to myself.
Kind Regards,
Dylan
