Extra Electric Generation On A Chopper

[poanoi]

Is there any neat way to install a 2nd generator on a chopper ?

I got a 1100 cc and am driving exclusively in Pattaya city, and i got the impression i have a electric deficit from cranking this engine around every 800 meters, So: is there any neat way to increase electric regeneration ?

[furyrider]

I don't think there would be a good way to do it. At least and have it look good.

I think if I were you, I would get a small scooter for my day to day runs of 800 meters "or walk " Unless you can run your 1100 for a 10km trip each day to charge the battery.

My wife has the same trouble with my 1300. When I leave for months to work she starts it for me every week but after 6 or 7 starts the battery goes dead because she doesn't ride it and sitting idle does not charge the battery much.

I have thought of getting a battery tender for when I am away. You could look into that and plug it in when you get home.

Had a Nissan Sentra with a notoriously bad grounding system. So i did a series of star and Y grounding connections throughout the engine/alt/batt/trannssmission, after that the car ran much much better.

I also added an extra positive wire from the alt to batt to supplement the OEM one, as well as the ground.

The stator can employ either one of two wiring techniques - star or delta, one of them gives more amperage while the other gives more voltage, i forget which one is which.

You can also rewire the stator with thicker wire to allow more current to be absorbed, but the winding length will have to be a bit longer to get the target voltage. If you use thinner wire the voltage will be higher , but less current. In car audio power supplies the transformer in hi-end amplifiers utilize wires (usually 4) twisted together to equal one, the advantage of this is to get both the voltage and current needed to supply adequate power for the rails while avoiding losses do to switching.

Sometimes using a higher grade enameled wire is all thats needed for greater efficiency. Enameled wire with a yellowish color is usually lower grade, while the redder colored wires usually from Germany are of a better grade and don't get as hot.

Finally, using two 6 volt batteries connected in series to equal 12 volts (13.2v in reality), will give you a lower ESR (the resistance of the battery) which will allow faster charging and discharge. Batteries with less plates charge faster, more plates give you more reserve but charge slower.

Check out 'First Power' batteries, normally used in computer UPS supplies, and for the really hi-end stuff look at Cyclon batteries, they charge almost as fast as capacitors with insane discharge burst rates.

Thanks for reply.

I got the small scooter, but somehow i like the big bike better

I also got a charger, but i live on 4th floor so it takes some effort to get it properly charged.

Still not a biggie except when i just came back from Cambodia after 1.5 week leaving the bike at a shop to get some chrome done the freakin battery was flat, and that did disturb me !

Is there any way to disconnect the thing that do away with excessive charge so i get an insane amount of charge when riding ? preferably with a switch so i can make it normal on the occasion where i might go on a longer run ?

ps i just saw the 2nd post, and will inquire Cyclon battery,

that sound just like what the Dr ordered

install wires for a trickle charger to be easily installed every night. if battery is done, you need a new one in addition.

ctek is an excellent tricklecharger

charging with more than 14,45 Volt will kill your battery in an hour or two. permanently

[poanoi]

I may have damaged my battery, if i'm forced to charge it up i will do it at high juice for 6 hour

[VocalNeal]

from cranking this engine around every 800 meters,

One has to ask? Why are you starting the bike every 800m? Are you delivering newspapers or the like?

I think the trickle charge option will work. Or a decent ride down Sukhumvit before going home.

[Timthai]

Yep, sounds like the perfect excuse to take a decent ride every couple of days!

...gotta slip out for a few hours to recharge the battery!

Cheers.

Heat kills lead acid batteries. So fast chargers are not recommended because of the high Amp involved.

I saw on ebay a solar powered trickle charger kit....with regulator. The panel is small so could be mounted on the handlebars.

I believe riding to Rayong for lunch on the beach would do a better job. I guess Rim Nam in Ban Chang would do at a pinch. Still on the beach.

If battery did not go down below 10.5v it will recover.

As you live on the 4th floor the solar option would work if parking area is bright, but it is one more thing to steal.

Riding for more than 15 mins and not stopping the engine every 800m would work just as good. Disconnect the battery if away for months.

agreed, max 15% of batterys amp from charger, so motocy batterys 1 amp charge is better than 4 amp charge, and more than 4 amp is death within months

what sort of bike are we talking about, I'd guess there may be a problem with your battery or charging system for it to apparently discharge so frequently although you don't say how often this happens, as already mentioned taking the bike for a run once or twice per week should be enough to keep it topped up, as for the difficulty you have charging - take the battery to your room to charge - seems simple enough.

starting and stopping after many short runs is very sore on the battery and over several days would eventually discharge it enough to cause starting issues, this also depends on how hard the bike is to actually start, the longer you have to hold the starter before it fires with dramatically increase or decrease battery reserves, my 1100cc bike takes a 1 sec button push to start it which is pretty good - if you are holding the starter longer than this you may have a problem, could need a good service plug change etc, or a compression test - low compression will cause starting issues, also the mixture may be off.

I looked up trickle charger but didn't get any wiser

Is that about the same as your local repair shop has or not ?

I got that already.

My bike require a pretty well charged battery, it will then start instantly, if so-so, it can take 4-5 sec,

if poor, it won't even crank around more then two turn.

It was discharged after ~10 days in Cambodia.

it was then revealed one spark did't work at all, while the other spark was in poor condition so i was told.

The answer why i'm fed up driving in Pattaya is that it is now too crowded, only if i have no other option will i leave my room, and then only to get what i desperately need.

My small bike does it within 200 meters, if i have to go to Carrefour i take the big one usually, -800 meters

[furyrider]

Try looking under Battery tender. I don't have the manufactures name at the moment but I have been looking at them. They are a trickle charge unit that comes with quick disconnect fittings that you install on the bike.

They monitor the battery charge and when at full charge they shut off.

How ever I am not sure some of that would be useful but you being on the 4th floor. But you can use it in your room and not have to worry about overcharge to the battery.

[poanoi]

Aha !

So it is pretty much a safety switch right ?

Well i will turn down the charge power a bit and charge no more than a couple of hours from now on,

it's only ~3 times per year i have to do it anyways, but i still have to change battery every 2 years

Are you serious????????????????? You live in Pattaya but because it's crowded you rarely leave your room.

AND then if you go on a 800 metre ride you take your 1100cc chopper

Well i think that when the rain stops it's time for you to find somewhere else to live before you start living under the bridge

[hearditallbefore]

They are also called a "battery tender". You can leave them plugged in for months at a time, solar and ac

Yes, i'm pretty much always thinking of somewhere else, like Hua Hin, Rayong, Trat, Sihanoukville.

Unfortunately my gf has a business going well here, or fortunately, not sure which

My catch is i'm on 4th floor in a resort (that charge me 1500 baht for electric even tho i dont use AC )

google ctek, excellent quality trickelcharger sold by many big bike shops. can be installed permanently in bike, so you only need to plug in wall when parked

[poanoi]

That sound very neat indeed !

Do you know any bike shop in Pattaya that has it ?

And about how much does it cost ?

[thaicbr]

Maybe!

or as another Guy mentioned solar charger.

or a dogs <deleted> solar rig.

as i recall 2k baht for the small bike charger, but not familiar with bike dealers in pattaya

vvp4x4dot com can ems, and red baron, both in BKK

have had one for years, and my batteries last for..............years

[BigBikeBKK]

Batteries are cheap. I replace mine every two years.

This looks pretty frickin awesome ! ......If i leave it somewhere i'll have full juice every day assuming it was some sun, .never mind the last 8 month crap weather

Does anyone know where i can buy ?

[smedly]

just go to one of the local hardware stores and buy a freaking battery charger for 400baht, they work just fine and offer quick or trickle charge, jesus it's not rocket science

[poanoi]

Thanks, but that wasn't helpful, i got a charger already, on my 4th floor, at home.

I want that mobile solar charger in addition, so:

Does anyone know where it is for sale in Pattaya/Bkk ?

Dunno. pretty unlikely you would get one in Pattaya. You could try this place http://katze.tarad.com/product-en-8328-MotorCycle+Harley+SuperBike+Battery.html
