4-12v to 6-8v W T-890 & OBC V2.05 Should I upgrade OBC?
 
I need new batteries in a 05 Precedent. After searching & reading here, I've decided to upgrade from 4-12V's to 6-8V W T-890's, thanks to Driver33b & Canine_Rescue_Pilot posts. I have OBC V2.05 with a Powerdrive 3 Model 26580. Should I upgrade the OBC? I know neither Driver33b & Canine_Rescue_Pilot did, but I'm at a lower version of the OBC and have read of problems with V2.05.

Thanks,
Michael

I would get a DPI charger disconnect the OBC and sell the powerdrive 3 and recoup most of your money back and your new T890 will thank you for it .

As long as the OBC is working I would not worry about it. If it gives you trouble down the road I would eliminate it.
: Edit: Sorry Swan we must have posted at the same time.

This is exactly the route I am going now with my 06 Precedent. :)

v2.05 was junk. It was supposed to have been changed under warranty on all fleet cars when they were new. This was the 2nd year of the 12 Volt setup and by 2006 or so, they'd made the decision that the 2.05 didn't get optimal performance from the batteries, so the 2.06 was released. A short time after that, the 3.0 was released, and then the 4.0..... Basically any OBC that was ever released for 12 volt batteries was eventually considered bad... A few short years after that, they quit blaming the OBC and started blaming the batteries. I think this is where they finally hit the nail on the head. I believe it was a battery issue all along, and not necessarily an OBC issue at all. All of the OBCs out there that were on cars with 6x8 volt batteries are fine. The new v6.0 OBC would work great in your application.

That's basically my conundrum. Do replace my OBC or bypass it and get a different charger? My range was fine with 4-12V's, but replacing them after after 2 years was well shitty and expensive. I got the T-890's for longevity, they should not be discharged as much therefor should last longer, at least according to what I have read here and elsewere. I am also replacing all the cables with 2 AWG EXCELENE WELDING CABLE BLACK OR RED MADE IN USA. when the motor or controller quits I will be continue upgrading to a higher torque motor and higher amp speed controller! Just waiting on things to fail to give me an excuse. :)

My vote is for an OBC bypass and a new charger. The OBC is great for a Club Car dealer because it logs vehicle data, but for an individual consumer none of this matters and it's an unnecessary feature.

So whats your choice for a new charger? A Lester Summit High Frequency Charger 19.5A that's on your site, DPI, or a Yewey?
