1987 Turbo 4Runner Odyssey Dual Battery + Accessory planning

[viesail]

Getting to the point where I need to plan out this system. I had always thought I would run (2) Odyssey 1200's via National Luna Smart Solenoid + upgraded 140A alternator and big 3. I'm now on my 2nd Odyssey in a few years because I didn't understand what the AGM needs (project car). I think I may still proceed with the dual 1200's, but I'm having doubts after learning about Lithium house batteries and the Redarc BCDC1240D. It would be cool to mount a Battle Born in the spare wheel area.

If I decided to stay with an AGM for the starter and house, would I be wise to buy the GENPRO10X2 now to keep my new Odyssey 1200 in shape while I finish some projects on the truck? I'd like to be able to tap into shore power in the driveway. Or should I just go for the BCDC1240D now, or is that too much juice for the Odyssey 1200?

FWIW: Consult with the Odessey gurus on this forum. IIRC, they are notorious for wanting a high charge voltage and Toyotas are notorious for only charging at about 13.9v - a death sentence. (Get out your multi-meter and check.) YMMV, but ask the question.


You really can't have too many amps for a lithium iron battery. A BCDC 1240D would be fine. Were it me, I would spring for the 1250.

Again, YMMV.

(Gotta love the abbreviations! )

Have you already swapped the stock alternator for a high amp unit? I had problems putting a high amp alternator in my '85 22r. It seems like they mostly come with smaller than stock pulleys, and I would throw the belt around 5k rpm. I'm still wanting more juice, so would be interested in knowing if you had better luck or which unit you're thinking about. I think I went with LC'S alternator, and ended up going back to a more-or-less stock unit.

I have not bought the LCE 140A Alt yet, but I have heard these issues on posts other places. Maybe it’s not the move then. This DC to DC charging could be the way to go.

I’ll be honest, I had to look up most of those acronyms haha.

How do I summon these gurus you speak of?

Just start a thread with "Odessey" in the title; something like "Best Charging Practices for Odessey Battery." (Or, if you prefer, "My Odessey battery died, again!")

I have never owned one of these beasts, but there are several folks here who have, with greater or lesser success.

Just post “14v” is sufficient to keep an AGM happy, wait 5 seconds and you’ll have plenty of attention ?
