Looking at those stickers on the back window I’d say that young man is no stranger to illicit substances
To be honest I would probably look at a home made wind turbine idea pole mounted above the container could be fed into a battery backup inside the container so you would have power available if needed for 12v LED lights and an inverter for power tools. Only other real option would be a small generator left in the container for charging etc. If the bike battery is down to 7.8v its probably toast at this point and starting the bike to charge it could screw up the charging system. anything below about 10v is going to be iffy even if you recover it this time. And the usual warnings apply about starting bikes with low battery voltage ...... Don't do it.
Voltage and current are tied together by physics for a constant power draw. If the voltage goes down current goes up. At best you overheat / burn contacts or the solenoid doesn't pull in properly and drops out ( the chattering noise you get with a flat battery ) At worst the solenoid pulls in and welds the contacts so it doesnt cut off the starter when you let go of the button starter melts down or the wiring melts / burns or a sprag clutch fails. All of which get very expensive, quite quickly
If you want to play with a very basic formula you can try Volts x Amps =Watts if you assume watts to be a constant eg 500 you can vary the volts by using Watts / Volts = Amps Therefore 500 / 12.7 = 39.37 A & 500 / 11.0 = 45.45 A will show how voltage changes affect the current drawn Most bike starters will draw 2-300 A over a very short period of time so you can see the effects of low volts on a starting system or an electric motor etc
I would be inclined to keep the battery at home permanently on an optimate or similar. The likes of large solar panels outside a lockup will only entice thievery methinks Two minute job to reconnect, long periods of non use over the winter months will feck a battery anyway I've got one of these https://www.amazon.co.uk/dp/B00604U...=9044981&hvtargid=pla-578948283592&th=1&psc=1 for battery restoration duties!
Basically if you change any single factor in the equation then it affects the other. But in the example you give the volts have changed from 12 to 8 so I dont understand your confusion.
If you take your idea of the electric fire @ 240 volts unloaded when you switch on the fire the volts will drop possibly only by 1 or 2 volts causing very little difference, but depending on the voltage source your input voltage may drop to 230 which is within the 6% allowable or even to 220 but once you start to recalculate your current drawn, you will see the difference 3000w @ 220v = 13.6 A or 3000w @ 230v = 13.04 A. As I said the original formula is very basic and does not allow for switch losses cabling resistance losses etc all of which affect the figures.
I have the same storage eg a lock up and no power. In the cold weather I take the battery out and take it home to get charged then sit till needed, if its more than 2 weeks Ill put it on the optimate again. The new bike Speed is a few more bolts to undo and do up so it takes 3 minutes instead of one, I still think it takes me longer to put on the gear than set up the battery before a ride.I know then when I do it that way that the batteries in top nick to start the bike .
Done nothing on the bike's today. I went to the Wycombe Swan. With all my Boys and family. I watched Snow White. I had a fantastic time. Haven't laughed so much for so long. Never though Pantomime could make me feel so good. Ride Free Joe.
Well, this morning I am checking tire air pressure, and loading her up for a few hundred miles to Houston TX then attend training and a few hundred miles back home.
I believe the best thing to do is have a back up battery ready to swap in. Depending on what type of battery you have here it would be a good thing. A gel type battery will not be able to be recovered after to low of a voltage or if it is frozen. A lead acid battery will recover but never be the same. A lithium ion doesn’t like to be cold or in a constant state of charging. Solar chargers are good for a trickle charge of a disconnected battery and not much else. Of course you can connect a few together and it will work.....Sort of. All of this is before my second cup of coffee so....Be gentle.
Yep, 2 batteries. Eventually, your current battery will die with the charge and discharge cycles. A new un molested battery fully charged and ready to swap in will have you on the road without a worry. I work maint. So I am all about the equipment and could care less about operator convenience.
ABBA stand arrived today, so a little messing about. Finished early and had plans to go out riding. I did a local run at work before I knocked off ,and 5 miles out of town, snow, so that was that. I might get out tomorrow.
Went out for a wee ride, the weather promised 7 degrees ,then delivered 3, so I did 20 miles then had enough, the road was wet and greasy and I couldnt keep my visor clean. It took longer to clean the bike. Anyway I timed taking out the battery on a Triumph Speed Triple, five minutes, @BB3Lions.
3 degrees, that's cold I hope you weren't singing "when will I see you again" to ya gentleman's bits! I'll wait patiently to see if anyone gets it.....
Drilled out the secondary baffles from the Thrux R yesterday as per previous thread by Bear (switched it up). I have always been a little bit underwhelmed by the exhaust note of an otherwise pretty flawless machine. Sounds much better, like a Big Triumph Twin should, still,not like my old 1973 Bonnie T120 though. The new crank on the TTR might have something to do with that.
Unpacking and making adjustments to the windscreen. I was getting a lot of dirty air yesterday with it in the low position. Ideally I would like to get lots of clean air in the low position and max protection in the full up position. Oh and its on a tiger XRX 17 model
Chose one of the coldest days so far to fit my new Tail Tidy to the Bonnie. Bought from TEC bike parts as a Black Friday deal. £50.00 instead of £69.00 and includes the LED rear light and plug and play wiring loom. Also bought a pair of black pannier rails from TEC for £25.00 as opposed to £45.00.
Talking of Moobs, I was doing my shopping in Asda today when I rounded the end of an isle and started down the other side I noticed a TV high up on the shelves playing a promotional video of some cleavage enhancing bra's (for women, not men). Had to stop and watch for a while, it was really good.
As the temperatures managed to get over 6c today, I gave the ST a proper deep clean and oiled the chain, all the road shite gets everywhere into every nook and cranny, so took a while. I strangely quite enjoy doing it.
Both our cars are sadly neglected, they manage with a monthly blast at our local hand car wash, I do them myself probably once a year, usually over Christmas, shows how bored I get!
I started off to drop the forks through the yolks, this afternoon. I thought it would take 20 minutes. The first bolt I undid had that stainless aluminium corrosion that cost me a bottom fork last year, so I said, "sod it", and undid all the front end ,anti-seized all the bolts and re torqued everything,then I stripped and rebuilt the front brakes, I wanted to do the rear too, only the light went ,so next time, and I got the forks dropped in the end.
