[RE-wrenches] Trojan IND9-6V settings with Outback FX and Flexmax 60

[Larry Crutcher, Starlight Solar Power Systems]

Hey Jay,

What do you have that is different than what I said? Attached is the IND9 data sheet. It shows 2.35 to 2.45 for absorb. I was pointing out that there is confusion: Trojan has multiple publications with different numbers on them.

HI Larry,

I was very curious about your charge specs as they didn't agree with what I have.
I have contacted Trojan and the specs you show below are for their "signature" line and not the IND line.

The official word on max C rate is 10-13% of max battery capacity for IND line.
The vpc voltages are in their IND product literature.

I'm a fan of high voltage charging, but I generally don't go over 2.53 Vpc for flooded. But, since the IND9 data sheet lists 2.45 Vpc maximum, I'de stick with that.
