    Subject: Re: Lithium Batteries
    This is a update on my lithium battery (LiFe) in my redrive VW powered MKIIIC. The battery has been in service for four years and is performing great. Every year I take my balancing charger out to the hanger to balance the cells. This year the cells were showing 3.33 volts on two cells and 3.34 volts on two. The battery was also showing 13.20 volts which is its rated voltage after 7 months in storage. Once again I didn't balance the cells because my balance charger can't balance the cells any better. With the lead acid batteries I had to replace the batteries every three years.

    Subject: Re: Lithium Batteries
    Good service out of the lithium battery, Rick N. I have been using this brand battery for the last 18 years: https://www.batterymart.com/p-odyssey-pc680-battery.html It is an AGM. I remember before the AGMs battery, acid attacking my Aerothane paint, epoxy chromate primer and 4130 fuselage. Was a pain in the butt. 2000 Sun and Fun Flyin, I was getting close to departing on my second flight to Alaska. I had used a lead acid battery from Walmarts for my first flight. Had to replace it when I got to Arlington, WA. It wouldn't crank the 912UL in Ashland, OR. Last year I had to replace my last Odyssey after 11 years service. In the hanger I have a small solar panel/battery charger/maintainer to keep it charged. In the last few years my MKIII has gotten very little use, but the little solar charger did its job. Of course the AGM weighs 15 lbs. Rick's Lithium weighs a fraction of that. john h mkIII Titus, Alabama From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Rick Neilsen Sent: Wednesday, June 06, 2018 11:08 AM Subject: Kolb-List: Re: Lithium Batteries This is a update on my lithium battery (LiFe) in my redrive VW powered MKIIIC.

    Subject: Re: Lithium Batteries
    Hopefully, I didn't mess up everyone's mind to badly with my msg below. My excuse is, I painted some sheet metal valley tin on the roof of my house in the hot Alabama sun just before coming in and trying to type an email. Let me see if I can straighten it out. 1994, I used wet lead acid battery for my first flight to Alaska. It gave up in Ashland, OR, but was able to limp into Arlington, WA, to change it with a new wet battery. On that same flight I had to get a jump start at Deadhorse/Prudhoe Bay Airport, Alaska. The new battery didn't like cold weather. 2000 Sun and Fun, Tom Pehigny gave me two Hawker Odessey batteries to try, a 12 and 6 amp AGM. End of my battery problems. Back then if I could have gotten a lithium battery and the money to pay for it, I'd have probably used one. Lithium wasn't available and the small AGMs were just being introduced. Please excuse my feeble attempt to write an email. john h mkIII Titus, Alabama From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of John Hauck Sent: Wednesday, June 06, 2018 12:08 PM Subject: RE: Kolb-List: Re: Lithium Batteries Good service out of the lithium battery, Rick N.

    Great video as usual Larry. I know you've tried the camera mounted almost everywhere on your plane. How did it do on the center wing section, was the vibration too great? At that location seems you would get the pilot doing his thing plus the view he gets during flight. -------- Jim P WAR EAGLE Read this topic online here: http://forums.matronics.com/viewtopic.php?p=480714#480714

    I would have preferred that, but the jello that resulted was just too much. Depends on the camera, but the ones that i have won t work there.
