P1000 For you electrical geniuses ....

I'd like to keep my buggy on a battery tender/trickle charger. I'll soon be installing a second battery system(still waiting on parts), and I'm wondering if there's such a thing as a single tender that will take care of both batteries. Something more "elegant" than attaching a different tender to each battery. In a perfect world, I'd wire both batteries to a receptacle on the dash and just plug the tender into that dash receptacle when in storage. I'm probably just dreaming too big ...

If you are installing a isolator between the batteries, theoretically the tender should charge both batteries when hooked up to either battery.

Or way overthinking it... Or would that be underthinking it... IDK..haha
If your battery is in good condition. It will trigger the TrueAM isolator after a little time and will charge both batteries at that point.

I've go the isolator kit sold in the store here. So one tender on the main battery will keep the second battery topped off when the main is topped off?

What they said.. hook the battery tender up to the stock battery and you’re good.

You guys are awesome. Thanks!

How does it work if you hook it up to that second battery? I would think it would only charge the auxiliary battery.. how would it allow you to charge but not allow voltage drop?

The way I've got mine wired, the secondary battery isn't maintained unless the primary battery is satisfied and the primary battery won't feed the secondary battery, if the secondary battery goes dead, if properly installed? But I'm no electrical genius, but it works!

That’s not what I asked...

The TrueAm isolator is ambidextrous.

When one [either] battery reaches 12.8v the isolator will close bridging them together. .

Got ya... Have they always been that way? Seems mine had to go a certain way? Also, how can it allow charge but not drain and be an ambidextrous type setup? In my mind i think of it working like a check valve.

You got it! If there is a drain on the primary battery and it not up to full charge, the secondary battery will receive a charge, pretty cleaver design. I run voltage meters for both batteries, just to keep up with what's going on.

I dont think they have always been like that tho. I know from v15 on has. We are on v18 now.

A battery is considered "charging" above 12.7 volts. As long as one (not both) is above this threahhold they should remain connected.... i think!

Once one drops to 12.7, it pulls opposite direction until both are at 12.7 for [x] seconds. Then the isolator opens and stops the bridge. Thus isolating the 2 batteries from each other.

This is what TrueAm has said about it anyways.

That’s AWESOME to know!!!

Get a SAE plug from blue sea systems and put it in the dash or somewhere you prefer. I got the idea from @ohanacreek, he put his in the front fender I think... Then you can plug your battery tender straight to that. I use mine all winter and it sure is handy.
