Re: Replacing Hall effect throttle with Potentiometer

I have had many further thoughts on this. As far as i can tell, the cyclone controller needs the 0-5v connection, current and ground, so the potentiometer I listed should work. The hardest part will be the translation of a mere inch to inch and a quarter of cable pull through a brake leaver to the f...

Replacing Hall effect throttle with Potentiometer

Hey all, So i'm planning on getting a cyclone mid drive soon. I know it uses a 3 wire hall effect throttle connection, and i'd really like to be able to build my own throttle out of a potentiometer. I hate all the twist throttles, and on my gas bike i use a brake leaver as the throttle. I would just...

Re: Battery help for a semi-informed beginner

thanks jd, i may consider cutting the charger/cell log corners. I do want the logging feature for power consumption tracking over time, but perhaps it will have to wait. Ditto charger; as long as the one i'm getting does 6s and has a hvc in it i could even just get one and charge the batts one after...

Re: Headway Pack Builders thread

hey everyone, im going to be building a 36v 24ah headway pack using the 12ah 10c cells, for a ebike i'm building. Having investigated thouroughly, it seems like the most plug and play solution for building a batt with these cells is to use the headway orange mounts and the connectors that ev supplie...

Re: Battery help for a semi-informed beginner

hmm... upon further investigation, it seems like it would be much easier to balance the cells if they were arranged as 3.7 24ah instead of 7.4 12ah... So two in a tube that only just fits them wont work for putting two in parallel...hmmmm.... perhaps ill return to the holes in cutting boards to hold...

Re: Battery help for a semi-informed beginner

hmmm looking at that guys splicing the crystalite thumb into the cyclone throttle is ideal. With a thumb throttle connected i can already see how i could build a rig to connect it to a brake leaver and have brake leaver throttle again and dual pull brake leaver on other side for both brakes.

Re: Battery help for a semi-informed beginner

Ooooook.... I might look at something screw on for the ends of the pvc, but to be honest i think for what i want it for ie cylindrical rigidity and not waterproofing or anything else probably just hand torquing of the end bits will work, if not a tension clamp prbly so its easily removable. But that...

Re: Battery help for a semi-informed beginner

i havent found anyone who has done it, but these headway cells have a diameter of 38mm, ie 1.49inches and are 15cm long. The all waterproof axiom pannier bags are 33cmx15cm. You can get 1.5 ID PVC pipe. I could stack them 2 each inside piping and then 4 in a flat layer and then do three layers, givi...

Re: Battery help for a semi-informed beginner

well after getting linked by someone over to evassemble, i'd have to go with 38140S 12ah Headways at this stage. I like them, they fit the bill, they are only 100$ to ship over like 26 of them, giving me 24 3.7v 12 AH 10c cells, to be assembled into two 18v 24ah packs in 6s2p or a total of 36v 24Ah ...

I've been looking EVERYWERE though for batteries and there doesnt seem to be anything available in Canada at anything less then about double what it is in the US. So ...

Re: Battery help for a semi-informed beginner

seems like id go Cycle Analyst after further investigation. Also, I guess with the chance of packs failing i'd order 10 of the 5 ah and use 8 saving two as spare (if they all work out of the box lol). I'd hate to be sitting waiting on one more battery to make the whole system work. Also seems like I...

Re: Battery help for a semi-informed beginner

hmm so i could get an iCharger 1010B+ as was suggested and charge the two 5s packs at the same time with it right? Also, as long as i have an intelligent lipo charger set not to overcharge and a watt meter that i pay attention too, there's no real need for a bms/lvc/hvc is there? The charger can lim...

Re: Battery help for a semi-informed beginner

also the more i read the more im leaning towards only 20AH to start with. So if i went with the Turnigy cells id now need only 8, so i'd paralell 4 packs to have two 18v 20ah and then series them to an lvh/hvc with the intention of charging the battery as one unit. Im looking at the tp packs lvc/hvc...

Battery help for a semi-informed beginner

Ok, hey guys, Im interested in building a 36v 960w cyclone kit mid geared ebike. I want to use it for the daily ride to school for the next three years. That means that i'd need it to do the 11km trip there and back each day, ideally without the NEED to charge at school. So 25km range. I've read tha...
