    Switch between parallel and series quickly

    That sounds dangerous, so I;m not going to attempt it :)

    I like this idea! I will use it in the future for sure, much more convenient...

    Switch between parallel and series quickly

    Alright guys, I'm totally happy with my ebike setup using 15 multistar batteries in series to up the voltage to 84v but when I try to charge everything I have to unplug all the batteries and use three parallel boards which take quite some time. Is there an elegant way of using switches to switch...

    Using a hub motor and solar panels to charge batteries

    Using a hub motor and solar panels to charge batteries

    I think I'm getting 7 50w mono solar panels....one at the front, two at top of the bike, two at the back at 90 degrees, and a small trailer for the last two panels as well as hiding my six 12v18ah lead acid batteries in parallel. I have a tristar 45amp solar controller which I'm going to connect...

    Using a hub motor and solar panels to charge batteries

    I read it, but it doesn't hurt to ask some questions.... Solar panels it is then! I'm forgetting the wild ideas about wind turbines and hub generators :( ...or maybe a sail bike....ehehe

    Using a hub motor and solar panels to charge batteries

    Allright, I'm convinced that an extra hub motor will not work....I might as well use my 200w solar panels to charge my extra battery on the go..... Quick question.......how about hooking up a PMA (permanent magnet alternator) instead of a hub motor to charge the second battery? Would that...

    Using a hub motor and solar panels to charge batteries

    How about this PMA instead of the hub motor? Looks really interesting http://www.windbluepower.com/Permanent_Magnet_Alternator_Wind_Blue_Low_Wind_p/dc-540.htm

    Using a hub motor and solar panels to charge batteries

    This guy has done the test for me :) It was much harder to spin a 350w motor by hand but much easier on a 1000w motor. He said max out (pedaling) he was pushing around 30v. https://www.youtube.com/watch?v=weQxnPz0Ow0

    Will do. Thanks

    Using a hub motor and solar panels to charge batteries

    That is a good idea. I have a watt meter on my lcd3 display....if I sustain 400-500w on my drive (maybe around 30km/h), have a 200w solar panel and see how much I can squeeze from the second motor (maybe 200w?) it might work....have to experiment more and report back

    Using a hub motor and solar panels to charge batteries

    Well, I have the extra motor sitting here (its for a customer) so I might as well do it and report back my failure rather than have these questions float in my head :)

    Using a hub motor and solar panels to charge batteries

    Here is the rough idea....has anybody actually tried this in real life? I'm not after overunity here, it seems like a good idea to charge the lead acid batteries while you are out so you can charge the second lipo pack while you drive ( over here its sunny 300 days a year) plus use the extra...

    Using a hub motor and solar panels to charge batteries

    I'm going to use a second motor at the front wheel to generate the power (not use the same one) plus i won't be using its regen function so it won't be dragging me down so much. I have space on my frame for all these.....my bike use to be 40kg more in weight (6 lead acid batteries!) but it coped...

    Using a hub motor and solar panels to charge batteries

    Hi there folks. I'm pretty sure this was asked before a million times but I need to get my ideas out there just for the sake of arguing.... I have build a 1000w/72v bike with the hub motor at the back. I have no pedals. I have a 10ah lipo battery (two 5ah 4s packs in parallel....range around...

    Lowering the LVC of a controller

    You are correct...it is the controllers fault, trying to save my batteries...when the stops occur i still have 12.4v left on each battery...plenty of juice left...56v of lvc is more suited to lithium batteries rather than sla.

    Lowering the LVC of a controller

    nope, a jump to 72v increased my range by 5km but that is all. That high LVC is killing me! Help :)

    Lowering the LVC of a controller

    Well, apparently there is an option in the KT-LCD3 display that changes the LVC by up to 2V. I have to test this out and see if it changes something.

    Lowering the LVC of a controller

    So do you think a jump to a custom made 60v lithium pack will solve the problem? Is 56v LVC suitable for it?....or maybe go 72v by adding another sla battery :)

    Lowering the LVC of a controller

    Hi guys, I have just managed to build my own e-bike from zero with the help of the atomic zombie guide. It is a 60v 1000w bike that is fast and exciting. My problem is this: I have 5 12v SLAs (17ah) in series (edited) and when I travel for about 10km everything is fine, but then gradually the...
