    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    a) I'm not selling it here. I said I'm just quoting my for sale ad I have posted elsewhere because I included all the details of the project, rather than re-typing them all... b) I'm not including my address, price or anything because this is a project overview intended to help others out, not a...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Wow, it's been nearly 2 years since I updated my original thread! I had totally forgotten about it but wanted to update it just for others as well as my own reference's sake. I hope this will help someone in the future. :) I've been riding my highly modified high performance electric scooter for...

    Infineon Hookup Help!

    Thanks dogman. I understand exactly what you mean, but what I don't understand is how to do this on this 12 FET because it has TWO ignition wires coming from the controller, not one like my old one. With one wire it makes complete sense to put a switch in series between it and be main + lead...

    Infineon Hookup Help!

    Got a question on this again. That + yellow wire that I was going to just solder to the main + lead does in fact come from the key ignition and carries battery voltage when key is on, 0V when key is off. My issue is that my Cellman 12FET Infineon controller has 2 red ignition wires (use a switch...

    Infineon Hookup Help!

    Hey guys, Finally getting around to finishing my modified 72V e-scooter with my new Cellman 12FET Infineon controller but need your help. The infineon controller has a (+ and -) main battery power input wires, however, the stock controller has main power input wires (+ and -) also have a third...

    BMS Connection Help

    Hey guys, Need your quick help for a sec. Hooking up my first BMS but frustrated at how to wire it in. Reason being is that I have printed off a few BMS connection diagrams and they are in complete disagreement with one another in showing where the P- (blue wire) and the C- (yellow wire) is...

    Headway batteries advice

    From battery matrix: - free 35A BMS. Had them mod it to 50A - free 3A 88.7V charger. I already had bought an 88.8V 5A charger from Cellman (Paul), so this free 3A is a backup so I can have one at work too for last minute long trips. - I also had already bought a 14 FET controller with all...

    Headway batteries advice

    - I confirmed with them Doc, they include 24 not 12. Pic is just a generic pic. - of course there is. The owner is an electric engineer from what I understand. He said they took the 35A BMS, beefed up all the traces, shunts and wiring to allow for 50A continuous for my application. It took a...

    Headway batteries advice

    Doc, I know we chatted about this before. Nice to see you're also going headway route. I'm just waiting arrival of my 72V 15Ah headway cells, BMS, charger, wiring and all plastic holders and bridges as one huge kit from battery-matrix.com. They custom built me a 50A BMS for free for it. :)...

    what would you do //40155 cells or a123 pouch cells

    Just wanted to bump this post to see what you ended up buying ROG130. PM me if you like. Reason I ask is that I'm in the same boat, except I'm debating between: 36V 15Ah http://www.a123rc.com/goods-1561-Lifepo4+36V15AH+battery+pack+for+700w+E-bike.html using 40155 cells...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Just figured I'd leave an update. Went for a couple spins on my 16s test packs and watts-up meter. Pulling the controllers max 34A for 2000 watts, 50km/h. After way too many weeks, days and hours spent i've decided on the following setup: 12x 5s 5000mah Turnigy Lipo packs for 20s3p 15Ah...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Rewired the small 20awg leads to the motor last night with 16awg copper wire. Should nicely boost efficiency and power as I could feel the 20awg fairly warm at 67V. Running the numbers it looks like I'll gain 2.5% or 1.6V at 33A/67V plus efficiency. I'll hook up my watt meter next and see what...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Anyone? Just looking for your recommendations for the easiest/best plug-n-play controller for 72V or 100V input. Debating Lyen, Kelly and Infineon 12FET controllers but I can't decide which would be the best choice. Not sure i can program the Kelly's take-off amperage down for the 20awg motor...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Well I had a chance to test this tonight. I took 4x Gens Ace 2500 25c 4s lipo packs and built 3 series harnesses for them with Deans. Worked perfectly for testing. So I'm currently testing 16s1p 2.5Ah for 67.2V peak at 33a for a nice modest 2200w (up from 500w stock). I took my GPS along and...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Alright just got finished pulling the hub on this almost new e-scooter. Hub is labelled MTL48V100100060. It's a brushless motor 3main wires 5 small ones for hall sensors. Looks to be 20awg wire on the 3 mains running the brushless motor after comparing wire sizes and measuring with my...

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    I've emailed 3 or 4 vendors to see if they can get me any data on the motor. BTW this is a HUB motor on my e-scooter. So I assume they're all brushless aren't they? I have no idea on the kv, but I'll see if anyone gets back to me. Hope this helps. Pic below.

    My Finished 72V (88.8V) 50A Highly Modified Electric Scooter

    Hi guys, So bear with me as I'm new to the whole e-bike show, but I'm not new to electronics or LiPo/A123/LiFe, etc. work as I fly giant scale RC planes and much of which I build electric setups. So here's my quesiton I'm needing your expertise on. Looking to mod my newly purchased 2011...
