V_Mark said:Looks well done. When I had an Ezip (2007 or 2008 model) it could take 36 volts with the stock controller. I ordered an empty battery case off of ebay and put a 12v10ah SLA in there and ran that in series with the original pack. For charging, I disconnected the series connection and charged with separate 12 and 24 volt chargers. I got rid of it a couple of years ago, but the thing really flew on 36v, with the catch of it being noisy.

littlebear72_91 said:Great thank you for the info, I have an older bike (the blue one, bought it on craigslist) with a serial number starting out as "ACA"
I see that this site sells controllers http://www.monsterscooterparts.com/currie-controller-izip-ezip-electric-bicycle-ac-serials.html
This link leads me to believe that the "BM" serial numbers http://www.currietech.com/dealers/w...new Currie kit has a 35 amp controller on it.

littlebear72_91 said:Bob I was trying to identify which controller I have to see if I could go to 36 volts and how many amps. Looks like the controller can do 36 volts and at least 20 amps
Actually ... as demonstrated by the ebikes.ca simulator, 36V 20A is a fabulous performance increase over the 24V 35A controller.dumbass said:littlebear72_91 said:Bob I was trying to identify which controller I have to see if I could go to 36 volts and how many amps.

Got ya.....Not trying to be a PITA but your numbers don't work out quite right. Why are you thinking you would get 36v 20a? That's only 720w and if you have a stock Currie controller (24v 35a) the stock controller would supply 840w. I'm thinking your stock controller running 36v would deliver a full 35a for 1260w. Otherwise, your taking a step backward.

I've been reading all this and I just bought an ezip for $30 from a scrap yard and after a little cleaning and a few adjustments the bike looks and rides great on paddling cause I don't have a battery. I'm looking to buy a battery for it and would like to know which one to get (looking to upgrade to 36v)DrkAngel said:Actually ... as demonstrated by the ebikes.ca simulator, 36V 20A is a fabulous performance increase over the 24V 35A controller.dumbass said:littlebear72_91 said:Bob I was trying to identify which controller I have to see if I could go to 36 volts and how many amps.

Performance from ~9mph and up is greatly increased, without the increase in damaging heat at lower speeds.
Also, the lower amperage controller produces a torque curve that produces the greatest motor output at near to top speed, rather than at mid speed.
Instead of the motor losing power above 10 mph, power continues to increase right past 20 mph.
Of course, you could produce the exact same power profile with a larger controller ... it just requires throttle restraint at lower speeds.
<50% chance controller supports 36V. You'll have to try-test to confirm.Albeegood said:I've been reading all this and I just bought an ezip for $30 from a scrap yard and after a little cleaning and a few adjustments the bike looks and rides great on paddling cause I don't have a battery.

I wish I can post photos but photos are too large anyway my controller says 09/13/2009 24v 35a, thank yous.
