Powervelocity: Are you able to sell the bluetooth programming add-on on its own for someone to retrofit onto a similar controller?

Re: EUROPE - [2nd] Groupbuy MXUS3000 v3 TURBO

Could you add me to the waiting list too please? 3T in a 26" rim if possible? if not then the bare motor will do. I can pay straight away. Thanks.

24v LiPo Electric Mower Conversion

Thought I'd post some info regarding my LiPo conversion on a faulty 24v 4Ah Li-ion (BLDC motor) mower bought from eBay for £30. I added 6s2p LiPo at 12Ah. The only problem that I encountered was the fact that the old battery had 3 terminals: B+ B- and a thermistor connection. Without the thermistor ...

Re: Battery in backpack vs. mounted to frame

I've ridden with batteries in my backpack for years, much prefer it this way. Means I can quickly lock up my bike and take my batteries with me. Also keeps my not so road legal setup looking stealthy. This is my most recent backpack which is heavily padded to protect my LiPo. http://www.amazon.co.uk...

Re: Chain guide for 42 to 44t ?

I run a 53t chaining and also had a lot of trouble with the chain dropping off, I tried all sorts of chain devices that I had modified to fit but none of them were reliable enough. As a last resort I fitted an aluminium chain guard to the crank. It worked perfectly, no more getting off every 10 mins...

Re: I keep having flat tires

Get a decent tyre inflated correctly and you won't look back. I've been using Maxxis Holy Rollers for years and can't remember the last time I had a flat! Plus they roll quickly and have decent grip off road due to the inverted knobbly pattern. http://www.chainreactioncycles.com/mobile/maxxis-holy-r...

Re: Connecting 2 x 48V 15Ah kettle battery packs in parallel

104v isn't crazy, I've just made that voltage setup using a Lyen 12 fet 4115 84-132v controller. I have enough spare lipo to to run at even higher voltage (150v being the absolute limit for the fets). I just had to include a pre charge resistor in my circuit for connecting the packs because it makes...

Re: 76v 13.3Ah samsung 20R pack with kelly 100-150A controll

Jeebus, that fat bike looks like a motorbike, do you not get the attention of the 5-0? The fact that the controller can output 150A peak for 10 seconds would be worrying if you weren't limiting the current with the CA. I'd take the battery manufacturers current claims with a pinch of salt if the BMS...

Re: Magic Pie 3 Modification

Yeah the later MP controllers may be potted but mine is open to the elements it appears :p. I'm well on the way to beginning building my new setup now. I ordered a Lyen 12 FET 84-132V High Voltage Racing Controller and a box full of stuff from Hobbyking, just waiting for it all to arrive. I might po...

Schottky Diode - Series Connection of batteries.

I have been looking into the usage of Schottky diodes to protect the built in BMS of two 48v 10Ah LiFePO4 batteries when connected in series. I understand this has been discussed exhaustively in the past with conflicting views as to whether it is even necessary. I have came to the conclusion that I ...

Re: Magic Pie 3 Modification

Thanks for the link OCD :)

Yes I'll be removing the entire controller.

I only call it unreliable due to the fact that that if it rains the controller will cut out due to water ingress and then will cease to function for several days.

Magic Pie 3 Modification

Hi, I built a Magic Pie 3 powered by a 48v 10ah LiFePO4 battery into my bike a few years back and am now looking to upgrade to make things more interesting. I intend to replace the unreliable internal controller with a 12 fet external from the likes of Lyen or CellMan. Also I will replace the phase ...
