50% of respondents didn’t know how to find out how many amps they were charging at.

So, what did I do? I reached out to various camper van facebook groups, THE home of Questionablly Reliable Crowd-Sourced Data. More specifically, I wanted to find out what the max amps people have ever seen going from their alternator to their batteries. I wanted to gather some real-world data from those who were charging their house batteries with their alternator. With 2/0 wire, as long as the house battery bank is kept within 12 feet of the starting battery, even at charging rates up to 149 amps, a 3% voltage drop will still be achieved. Most applications will never see amps that high nor are most alternators capable of putting out that many amps. 2/0 wire with 105☌ insulation under 50 feet in length is capable of handling currents of up to 330 amps. 2/0 wire will be enough for 95% of applications. Wire size for Battery Isolatorīlanket Statement: Use 2/0 wire. Lithium Battery Isolatorĭue to the resting voltage rates of Lithium Batteries, you’ll likely want a lithium battery specific Isolator.Īlthough a normal battery isolator shouldn’t ‘damage’ your lithium batteries, it simply may not disconnect properly when your engine is off as it may see the higher voltage of the lithium batteries as ‘charging’, which will keep the batteries combined. It will typically be stamped onto a metal plate on the alternator itself. The max amps your alternator will output can sometimes be found in the spec sheet of the vehicle. Size your battery isolator to handle the max amp output from your alternator.

Although you’ll likely never see your full alternator output amperage going through your isolator, it’s really the only base line you’ve got. Your battery isolator will depend on the size of your alternator. This number is simply the amount of potential amps that could be flowing through the device from your alternator to your house battery bank. Most Battery isolators are rated in terms of amps.

If you’ve just stumbled on this article directly without seeing that, there are likely some things we’ve already covered.

This is just one part of an overarching “How to Install a DIY Camper Van Electrical System” series. I know it has been done, Eric Sargent's guys did it on the white 200 in a recent video he posted.A Battery Isolator combines the ‘house’ battery bank that runs your lights, fans, refrigerator, computers and such to your starting battery so it can be charged by your vehicles alternator. It also seems silly to use a relay (I guess technically it is an integrated circuit) to switch a relay, to switch another relay. I suppose I could use a Switch-Pros button set on momentary to switch an external relay to do this, but the idea behind the switch-pros is to get rid of as many of the extraneous components as possible. How would you accomplish this with a Switch-Pros setup with the minimum number of extra components? If I was using a regular relay, I think I'd just use the input/control (pin 86) to switch the ground (on pin 30 and 87). Positive makes sense for most accessories, but I need to link to ground for the SBI. I'm doing all of my accessory switching through a Switch-Pros 9100, which (as far as I can tell) switches the positive side. It has a blue wire that needs to be grounded through a momentary switch to "link" the batteries to self jump start. I installed a Redarc smart battery isolator. The intermittent does need to go to ground when the SBI is used for self jump starting, in the BCDC/SBI combo.
