Rear battery to Alternator Instead of Front Battery

[clickclickw00t 10+ year member]

I have a stock front battery and I just got a Kinetik Hc1400 in a trade.

I want to avoid getting an isolator if possible. WOuld it be smart for me to run the rear battery and connect it to the alternator positive instead of the front battery positive? Would this cause any problems?

So instead of

Front battery positive to Rear battery positive

it would be

Alternator positive to front battery positive, and alternator positive to rear battery positive.

Would this eliminate the need for an isolator? Could it cause any damage?

Thanks!

Hate to break it to you, but it's still all one electrical system. You're not separating the batteries by doing that.

Install your trunk batt and remove your front batt. Then save up for a 2nd Hc1400.

The shop I work at got me a really nice 200 amp solenoid. Should I run the rear battery off the alternator or directly to the front battery? Will I cause any damage if I go directly to the alternator?
