Howdy Folks, some context:
Since I've got a 170a renogy Li battery, I've realized it wasn't getting full charge from my keyline 140A isolator. After investigation I discovered the amazing world of multi-stage charging that lithium batteries like.
So I proceed to buy the new Renogy 40a DC to DC charger, which is supposed to solve this problem by:
- Keeping constant 40a charge output
- Use a multi stage charging algorithm
- Boost voltage to compensate for cable loss
This is the one https://www.amazon.com/Renogy-Batter...omotive&sr=1-1
This darn thing is not as easy to setup. Unlike the keyline charger which is a VSR (turns on when it senses the voltage). This one needs a positive signal input to activate and start charging.
The manual mention to connect the vehicle ignition signal so its hot when the vehicle starts.
I did this before for my reverse camera installing a cable out from the fuse box which felt pretty sketchy, soldering down there I managed to melt a bit of the fuse box plastic plastic so I was wondering if there's a better way to hook up from the ignition bus contact, it can be inside or under the hood.
I hope I explained myself right, I don't know much about cars terminology but I'll be happy to answer any questions
