Nice work Yped. That excellent video will help anyone else with the same project in the future. One of the halls went out in one of these motors I rewired and not wanting to unspoke/respoke the whole wheel i just swapped the controller to a sensor-less unit so maybe i would recommend replacing...

I just returned home from a thoroughly enjoyable 40 min rain soaked ride. I think my 2Kw commuter is getting jealous of the time I am spending riding the Aprilia. This bike really needs a lithium upgrade. Anyone know offhand how many volts the stock controller can safely handle? I know this...

Cheers Tony. No, i didn't buy that one. I live in USA, Washington state. And Hiya Ken. Thank you and everyone else that has contributed here for all your input. About disabling the speed limiter: I am pretty sure I read about it in this thread but there are 37 pages here as of this posting...

I recently picked up an Enjoy for a reasonable price with the intent to modify it to a 36v system with a throttle. It looks to be very lightly used. to my surprise the original battery pack took a charge and seems to be fairly strong. it was kind of an underwhelming ride until I clipped the...

I bought a 48v 16s lifepo4 BMS from them. I played around with adding their inexpensive Anderson connectors and other such accessories into the order until it raised the already high shipping cost. it all showed up. it all worked. If I was looking for an entire system I would buy from a dealer...

This adapter has worked well on my EVG SX for 1000 miles so far. http://www.ebay.com/itm/New-MTB-Bicycle-Bike-Rear-Disc-Brake-Adapter-Kit-170mm-Black-/370996854961?pt=US_Brakes&hash=item566122c0b1 the 170mm kit was a centemeter or so too long. I had to remove the adjuster bar's lock nuts (I...

I had to remove the fuse to get the plastic cover off. By "acting dead" I mean that the BMS's / PCB's wont supply voltage under load. (pack current is at around 53v.)

avoided it as long as I could. like i say I have 3, all acting dead. so I am not too concerned with playing around with one of them.

huh. guess I have 48 of these. #s all match (ya, after posting the pic i noticed the YLE and did a Google search. Doh!) http://www.yiklik.com/index.php/products/detail/23519 3c max continuous 10c max impulse all cells are between 3.3v and 3.35v So any one have an idea how these BMS's...

I picked up 3 of these packs. the seller had little to no info on them. just that he got them out of a storage locker and that they have been sitting around for at least 8 months. the cells seem good. after opening up the cases all the packs read around 53V. I'm still determining if the BMS's...

"Advantage" is hard to quantify completely. Lifepo4 or LiNiMnCoO2 chemistry will be more plug and play, Lipo will give the most bang for the buck in terms of amps/watts per weight and dollar but will require a bit more hands on maintenance. it just depends on what you value the most. DC

good set up Wesnewell. with the added bonus of being Australian sourced. Kudos. I think Dand214 was saying the battery Battery pack Cellman has now is a decent option. And within the price range. DC

Hiya Jordan, Guess I'm the 1st to chime in here? Ive been very happy with my 500w direct drive motor kit and with my dealings with Cellman at EM3ev . http://em3ev.com/store/index.php?route=product/product&path=36&product_id=54 I used the least expensive shipping option (SAL I think it...

I found a cracked solder joint in one of my 36v 500w heinzmanns. pretty simple fix once I got the motor apart. just saying. there are many threads detailing the process of dis / reassembly around here. the quick version is remove the axle nuts and spacer on the cassette side, unscrew all the...
