Not that I'm storming into the middle distance with all guns blazing.. just that I wanted to make it a bit easier for myself if I need to put Thumper on trickle charge every once in a while.
Instead of having to remove the battery box every time, I have fitted two charging poles to the box and wired them into the battery terminals. Now I can connect the charger with a couple of banana clips and I can also check the voltage with a touch of my voltmeter. An added bonus is, that I have a 12v take off if I need it without having to get the cover off.
I separated them to each side of the box so I don't risk dropping anything across the two poles and cause a short circuit. Negative on the left, positive on the right. The whole job cost me pennies and the only hard part was the soldering.
Here's the result:
