Ask a young register clerk to make change without consulting the screen and their priority hand starts making those reverse clawing motions trying to expand their mind like it was a touch screen.

Darwinism is still hard at work. Need to divide 12 by 2.66? Can't be done without clawing. Humanity 2115: priority hand will be enlarged like a sand crab's. Unable to focus, incapable of conceptualize with making clawing motions.

Making battery charger controls is more fun. Well, time to stuff the stove then collapse like the chickens did. The digital challenge wore me out yet again. Freakin' pinball machine illogic.

Make a phone call unless crawling underneath a car? Uhm, I swear that somewhere in there, you can voice activate phone calls. Google it on your laptop for "Android jelly bean 4.2.2" or ice cream sandwich 4.1.2


A fascinating homework read for you.

i also frequent the instructibiles website, i'm usually looking at motorized gizmos, lasers, other Neat stuff

Hi Reed,

Excellent information. Unfortunately I need a bank that can survive -40. As you pointed out I would not get much in the way of wattage from the solar, especially during a day where the sun is only up for 8 hours. There is no shore power where I needs must store for the winter. I could, in theory, super insulate the container for the LI and use a heat source--but I really believe it is not yet practical.

I did receive information from one of the 12 volt LI makers and they suggested that I must have heaters in the storage area for the conditions where I live.

A heating "blanket" of similar wattage would probably be sufficient to keep the bank above freezing. Others claim that LFP will not be damaged if the charge rate is below C/10. Doubt that solar will get above this rate in winter time.

We did leave the system running at our older son's place when we took off to spend 12 weeks in Honduras and Guatemala a year ago. His place is at 7800' in mountains of northern New Mexico and temperatures dropped to -20 F (-29C). We noted no change in capacity when we returned. Probably never dropped more than -400 W a day and the charge rate would have probably been about C/20 or less.

Mex,

Were you trying to make a roundabout reference to the LM555? I retired from the place that made and sold that IC. The next group over tested each one before ship on $300K (price back then!) Teradyne testers.

If so, you may have meant "seeing just how many milliseconds I can squeeze out of a 555" ... instead of how many Kilocycles. ;)

Damn it MEX! :B

For us not so technical people, are these Megawatt (or Meanwell) units compatible with some kind of remote voltage control? I have a nice place to mount one close to the batteries but far from accessible. It would be nice to be able to optionally equalize with it without removing the sofa.

Now Mex is mad at me! :B

If Mex is mad at anyone, it's me, for giving him that damn Galaxy S2 Smart Phone. It has caused him more grief, caused him to ask more questions, PM's me almost weekly about how to do something on it, how to find something on it, how to change something on it.

I deserve a darn PHD in Android OS... I should have just reinstalled Gingerbread 2.3.4 back on it to handicap him a little bit and slow all the questions down before letting him play with some smoking hot, latest and greatest 4.2.1 or 4.2.2 Ice Cream Sandwich version with a ton of bells and whistles.

Last I heard, he was looking for some damn vent caps on it to dip to see if the weak sister is looking good, or being bad. :S

Hi,

I got remote water filling and found the plastic was brittle. It was nearly as costly as purchasing a new battery, too. That is why, next time around, I'll go AGM (unless LI becomes affordable and usable at low temperatures).

How have you wired the "extra" bank?

Stirring the batteries is a good idea. Most of us drive down the road. Stirring in storage can be accomplished with 60 watts of solar per 100 amp-hours of battery bank when using a good charge controller.

Pianotuna,

I don't really want to go with the watering system but I really need it on the remote pair of 6V GC's. They are mounted between the frame rails of the MH in an enclosed but vented battery box. Plenty of room under there when the slide rooms are out but not fun to access. They are connected to the main bank with 2/0 welding cable, about 10 feet in length.

I usually do not let my MH set more than six weeks, even in the winter. So long term battery float should not be more than six weeks.

Thanks,

Greg
