Damn, my book club meets up then! (again) Found the lost part by the way. It was a part of the charging system and removing it definitely improves acceleration at the expense of charging up the lights. All measurements were done with a fully charged-up battery, on this analogue voltmeter: http://bad...

Heh, yeah, there is that.

The lights were running off a 12v battery when I got the machine... seemed to work ok too until I started messing with the system.

That's a relief - will check with another voltmeter. Should the hub be oiled? Thinking of going back to the idea of overamping now...

PS - Is it safe to test the charger with a voltmeter? And should I oil the hub motor - it's a bit noisy, also I've tested voltage there and it runs that at 48V as well!

Woah! That's some mission! Testing... yup! Still 48v! And you've definitely tested yours and found it's 36? hmmm.... Well, I have a different model of the s200, mine has bicycle spokes - as seen here: http://www.austinev.org/evalbum/1370 Serial number is: S200406006 I'd guess from that that the bike...

Is there any reason I couldn't run my bike off NiMHs? As long as I made sure to match the voltage and amperage? I'm sorry if I seem pushy or anything, it's just that I need the info fast as the batts are a sale item- and depending on what the answer is and if I buy them, I could either end up with a...

I've decided to replace my lead-acid battery with dry cells rather than mess about with over-volting, but I'm not sure as to the voltage of the Sakura battery. I was wondering, has anyone ever taken a voltmeter to their Sakura or other sub-moped battery? Because mine reads as 48v despite Sakura's cl...

I'm going for a NiMH chemistry, likely in AA as it's cheap. I'll be making up packs of ten and then hooking them up to make a 48v battery. Do you have any advice re charging (I know they are charged at 10% of their ampage rating and that's it, but I'm nervous about charging two sets of 12v packs wor...

You're right, the real problem with this bike is something far more fundamental - a design flaw if you will. Without the approx. 12 kilo weight penalty of the wet cells, this bike will really move - possiblyt even up to the point where I might derestrict the speed and register it with DVLA! NiMH (or...

More on the "F" type from a US distributor (note the lower prices and lack of international shipping, grrr!) http://www.all-battery.com/index.asp?PageAction=VIEWCATS&Category=230 Is this the fabled NiMH invented by Professor Stanford R. Ovshinsky, the one they put in the EV-1? It certa...
