    SLA back up battery recommendation

    Is the discount price for this about $41? This is the price it starts with. I'm not seeing the discount price pop up as you say. Do I need a 'discount code"? Also, can I use the controller I already have? I got it from 'Dogman' and is a replacement that came with my Aetoma motor from about 5...

    SLA back up battery recommendation

    Okay I'm in Bay area California. What/who is a good source for RC Lipo or other lithium battery pack? I'm not going to put anything together. I just want to buy a five plus amp hour pack that will work with my controller 36 volt. If I can get the charger pretty cheap then that sounds good.

    SLA back up battery recommendation

    If I go to a local shop to ensure 'freshness' then the price of 3 8ah SLAs is not worth it (3x$35). On the other hand $17x3 or even less (from one of those battery outlet websites) seems worth it to spend as a back up to my lithium pack...but no guarantee of freshness! I'd be willing to spend...

    SLA back up battery recommendation

    I need a back up set of batteries which I'd like to be SLAs. I recently had a bad experience with Universal Batteries (3x12v 8ah and 9ah sets) in that they clearly had been sitting on a shelf for a long time and so didn't last very long, or in one case, dead upon arrival. I am using them...

    Does anyone have a contact for this person. He knows of a part I need for my battery pack. The email address I had for him is not working.

    Trouble shooting help needed

    If I did touch red to purple and damaged (controller ?) would I have seen, heard or smelled anything? I will try connecting 4.5 volt battery to test throttle as you suggest.

    Trouble shooting help needed

    I'm definitely not an electrician by any means. However, I know not to cut into live wires. On the other hand (this is where I probably am not so smart) I did start touching those wires (from throttle leading to the controller) to each other (with battery connected and controller switch on) to...

    Trouble shooting help needed

    I am suspecting throttle. I cut the throttle wire and I see four little wires (white, red, purple, black). I noticed -almost by accident- that when the black and purple wires touch a big spark occurs; nothing seems to happen when other wires touch. What can I do to determine whether or not the...

    Trouble shooting help needed

    Thanks. How can I test to be sure it is the controller? Especially if the lights on controller are on and blinking like normal and the throttle lights are on when battery is connected.

    Trouble shooting help needed

    Thanks. I don't know what, or if I have, a brake switch. I have a volt meter. Since the indicators on throttle light up, some of the wiring and connectors must be OK...but I need your help in understanding which wires/connectors those are.

    Trouble shooting help needed

    4 year old Aetoma front hub motor 750 watt, basic 4 year old stock Aetoma controller for 36v battery packs. Problem: turn throttle and nothing happens. History: for a couple of years would get occasional cut outs of power (less than 1/2 second) a few times per week. The frequency of this...

    life of battery

    Forgot to mention that I have the Aetoma front hub motor -probably new 3 years ago. It would seem it was their stock motor with a stock controller (36 volts).

    life of battery

    Thanks to everyone for their input. Yes, to the gentleman who included a link to the battery, it is in fact that same battery pack. Well, if I attempt to digest and integrate all of your input I ought to be happy if I make it to the end of this school year (June 2013) with this pack. Thanks, Jeff

    life of battery

    I have an ebikekit 36v 10ah purchased about 2 and 1/2 years ago or so (just before they stopped selling them). It comes with a rack adapter so that it can slide onto my back rack. After a little over one year of commuting (7 plus amp hours round trip, much less in the summer months; charging...

    free wheel versus cassette

    I went the cheap route and kept my freewheel, bought a $39 wheel...and new pads since the lack thereof is how the brakes wore out the rim in the first place. Keeping an eye on the pads is crucial -thanks. At a future date I'll either learn the art of lacing to make a better wheel or buy a good...

    free wheel versus cassette

    OK, another detail regarding number of teeth on the cassette I will buy. I currently have on my freewheel: 13-28. I like the 13 as it makes for comfortable pedaling at full speed. The 28 is a nice way to start and to get enough speed up to engage motor safely. I know my LBS has in stock a 13-30...

    free wheel versus cassette

    I have a front hub motor (aetoma). So, cassette is the vote. Any comments on a make or kind of a rear wheel. Otherwise I'll go with the LBS's basic wheel for about $60 plus cost of cassette and chain -since it is old- and I've been told when getting a new freewheel or cassette to get a new chain...

    free wheel versus cassette

    Does anyone have a view about free wheels versus cassettes. I've been using a free wheel because my bike (Magnum from I believe Costco) came with one. But now my break pads have worn thin the wheel. My LBS suggests a cassette as they say it's stronger and serviceable (bearings etc). I am...

    36v lithium charger comparison

    OK, so it is not a kingpower charger that ping talked about. I know it has two phases because after about 2 hours or less (after 4ah used in riding) the light shifts from red to red/green and that phase goes for about 4 hours. In general, the lesson I am learning is that it is not so good for a...

    36v lithium charger comparison

    I have both chargers below and use one at home and one at work to commute. The first one has two cycles I believe, first to charge and second to balance, with a total time about 6 hours. The second one charges in usually 2 plus hours. This doesn't make sense to me as the first one is supposed to...

    Testing for Amp Hours

    Thanks for the reassurance that my battery -currently at 90% capacity- is about where it should be. I will be playing it safe from now on by charging at work in addition to my charge at home.

    Testing for Amp Hours

    Well, I did hook up my watt meter to my ebikekit 36v 10ah LiFePO4, rode it till it was empty and found that it has 9ah in it. For one year plus I have commuted to and from work plus or minus 7.5ah per day before charging at home. From now on I will be charging at work too which will cut the...

    rebuilding front wheel

    Thanks for all your advice. yeah my hunch would be to not trust the LBS although one shop which is very small I might. I guess I'll have to learn. I like the idea of tightening them since they haven't been. I'll start there.
