Pedaling a regular bike
Norm:
Thanks Hiker....yeah it just goes to show that an EMC conversion is a lot
simpler....would like to hook it up chain drive someday tho'.....looks like
his is about1:3 ? Mine would have to be about 1:6 somewhere around there

Starting to charge a bunch of my 12 volt 1.3 amp/hr NiCad batteries
with my 'smart charger' a special sensor monitors the battery at
all times.....takes about 40 minutes to fully charge one battery
(14.2volts) then it only gets slightly warm ....not almost hot like
the craftsman chargers do the battery paks......
Truth is the charger gets hotter than the battery and quits before
any danger of overcharging the battery..... ;)
Fairly decent charging rate.....3 batteries in total time of 2hrs according
to the meter (bike digital odometer time speed and distance......
about 6miles at 3 mph.
I don't care what the doc says.....my knee feels a lot better with
this pedaling I done today than 'taking it easy'
Next project an exercise bike that covers actual distance while
charging batteries.
Norm.
( oh yeah the smart charger is me BTW) :)
bj:
To me, less heating in the battery has to be a good thing. I've always been a bit concerned on how
hot my DeWalt's get.
Added bonus if your knee felt better. Truly a "smart" charger. ;)
Norm:
Yep, It would be nice if they had sensors on the batterys that
cut off just a little bit sooner.....but then it's probably designed
that way so the batterys don't last as long.....sell more batterys that way . ;)
Norm.
BTW ....working on a LED lamp that plugs onto the top
of a cordless drill batt.pak uses one of those cell phone
plug in cigarette lighters can use 12, 14.4, 18, or 19.2 volts.

Hi Norm, I do the same thing with my car tires. I inflate them to the top of their rated pressure. I don't race my car or drive it into curbs much so I am not overly concerned with blowing one out from over pressure and besides I do stay within the top of the rated limit anyway. The ride is a bit less cushioned by the tires, but the rolling resistance should be less overall. I have one of those continuous mileage monitor things on this car, a hybrid, and also having had about 10 or 12 plugs in tires before I changed them out, I can tell the difference between a low tire and a fully pressurized one. This gasoline stuff is getting a bit pricey around my parts so properly inflated tires are worth the effort. Rich
