Double Battery Adapter

Great product quite surprised how well it works just trying it out now has ran my 40 ltr fridge for 12 hours and still counting on 2 4 ah batteries 👍

Cool idea as my fridge might need to run for longer before coming somewhere to charge and I can leave the setup without the need to check a swap batteries when hiking.

This is a great addition to enhance the versatility of your 18volt set up. Used it on a golf trolley, a fridge, testing trailer lights and there will be more. I tried to build one a few years ago but got too busy to complete. Cheap and handy.
