    From: "bobnoffs" <icubob@gmail.com>
    soon as the weather warms up a little [50 deg] i want to run my avionics and get limits etc. set. i have decided i do not want a power supply that could fry something if a knob gets bumped. i have gotten along 50 yrs without a power supply on my bench and can easily live without a variable source. anyone see any problems with connecting bench power thru the 'cig lighter' plug in? it's 18 ga wire and i would never pull more than a few amps. had i read something that powering an alternate field wire is not healthy?

    Subject: Manual Battery Switch
    From: C&K <yellowduckduo@gmail.com>
    Any recommendations for a reliable single pole manual battery switch that would replace a traditional battery contactor? This is for a rotax so starting current is relatively modest. There are lots of them listed on Amazon, ebay, and automotive suppliers but all of them seem to have complaints of falling apart or failing to work after a short time. I would like to mount it on the engine side of the firewall and arrange mechanical linkage to operable it from inside the cabin. thanks Ken

That's how I get 'shore power' to my RV6. But don't just assume that 'it's only a few amps'; verify actual load. My panel is probably pretty typical for VFR panels with 'glass' flight instruments, and the 18 ga supply wire gets fairly warm. I've just built another cable using 16 ga, & will see how that goes. If the field circuit concerns you, just pull the field CB or open the switch. I understand your concern about accidental OV, but there are numerous advantages to a fully controllable supply where you can limit current as well as voltage.

    >anyone see any problems with connecting bench power thru the 'cig >lighter' plug in? What is the power source? I used to sell a power supply in this class for about 3x the money. Sold quite a few. Builders would power up accessories on the bench or, on occasion, power up their airplanes with it. https://tinyurl.com/y3vww5uv > it's 18 ga wire and i would never pull more than a few amps. It can't do anything worse than not work and you're not going to crash your workbench. Certainly gazillions of the things are still in service in automobiles after about 100 years . . . so why not? > > had i read something that powering an alternate field wire > is not healthy?

    Hi Ken Not cheap but I'm using a Flaming River FR1013 on the starboard headrest of Rotax 914 powered Europa. Battery is in rear. I looked at a number of switches, even bought some and didn't like the looks of them, not robust enough. I'm not flying yet but do like the looks of the Flaming River. They sell a number of battery disconnect switches: https://www.flamingriver.com/battery-disconnect-switches?p=1 Ron P.

    when i use the 'bench power 'source i plan to only power a small part of my panel at a time. a couple amps. my questions are1. is there something i may be applying power to that may cause harm the way i plan to do it and 2. can anything detrimental happen to the charging system if power is applied to the field wire. sorry if i wasn't clear. i know this is kind of ambiguous as panel wiring varies.

I buy the cheapest version I can find at the time, and it 'just works'. FWIW, there's been some internet chatter lately among the RV-x drivers that the current (pardon the pun) crop of Odysseys have had less than stellar lifespans (and they obviously extract a premium from your pocketbook). I've always gotten 4-6 years out of the no-name versions, with the only exception being one that had a pin hole in the case (shipping damage that I missed prior to installation). Even it lasted about a year before I noticed diminished capacity. FWIW, there are some higher AH versions available in almost identical case sizes. The naming convention=C2- for most is like the PowerSonic: 12(voltage)18(AH)followed by another zero. If=C2- you search for '12200 S LA battery' or '12220 SLA battery' (and read the specs carefully), you can get a 20 AH or 22AH that will fit in the same space, for about the same money. One thing to notice on the 'no names' is that many are intended for deep discharge applications (powered wheelchairs, etc), and will have slightly higher internal resistance than a PC680 'starting battery'. By going to a 20 AH or 22AH version, the internal impedance will be roughly the same as the PC680 (meaning same or better CCA), and the battery's *capacity* (total energy content) will be 10%-15% greater than a PC680 (stuff will run longer after an alternator failure).

One measure for comparison (the easiest to find) is CCA (cold cranking amps). A harder one to find in docs is internal resistance (impedance). The PC680 is 7 milliohms (0.007). Most of the no-name stuff will be around 0.008-0.015. The MM referenced is 0.014, which is still plenty good enough to crank a 4 cyl Lyc, and would probably crank a 6 without too much effort.
