Keith (Melbourne, AU) This is my second box, I got this one to help set up for my grandson to make a lithium battery box with a dcdc charger attached.
The Merritt female is a bit loose compared to my first box that has a tighter fitting plug the new plug is a bit different ,that’s why i gave four stars,the product does everything that We want ,making it portable and weight saving ,attached to the cars charging system by an Anderson plug, I put a 100 amp lithium battery inside with a shunt also.

Awning Saver
Our caravan awning was starting to show the signs of being out in the weather for 10 years. With the Awning Saver installed it is hoped that we might postpone the inevitable replacement for a little longer. The Awning Saver was easily installed and gives some peace of mind that the awning is less likely to separate from the caravan at the point of attachment.
