My brother needed a new battery for his side x side. He bought a Bosch Lithium battery group 20 size. It was working great until it just died and got very hot and was smoking (venting?). I figured I would pass along the photos. Only used it a few times. Lucky he was only three miles from...

I saw this YouTube on the Victron website… That’s one sweet electrical setup.

Hello Everyone, I am looking for how to make those little electrical connectors that go on Fans and other small draw items. Also I was thinking of making my own connectors for the Tenery 5-in-1 meter for my own batteries - see photo. I just don't know the proper terminology to find the items...

Hello Everyone, I have a 2000 Monaco MotorHome. Last year I installed a 800 watts Solar and put in a bunch of Victron Equipment. The batteries needed replaced and at the time I was trying to decide between Lead-Acid, AGM, and Lithium. I really hate dealing with the acid on the batteries...
