Just saw a new DC to DC charger from Renogy on Amazon for $129, seems to have quite a few features for a relatively low cost. 40 amp model is $199
For sure beats (in my book) running a solenoid etc which ends up not being much cheaper. Downside of course is charging isn't quite as fast, but should be adequate for most of us I think. This makes it pretty darn easy to add in another battery and even do a quick connect type system where you only install the second battery when you need it as opposed to being installed 24/7. I know a lot of us don't care about having a second battery for self jump etc and mainly for running a fridge/electronics for the weekend.
Hell, I have a dual battery/charger setup and I almost want this for a 3rd battery/box that can easily go in/out of the truck yet still be charged from my existing wiring. Hmm lol.
From Renogy:
Description
This 20A/40A DC to DC Charger is designed to charge secondary batteries while driving using the primary battery connected to the alternator. It is able to charge: Flooded, Gel, AGM, and Lithium batteries using multi-stage charging.
