A look on the other side just to show now wires showing there either.

Thanks for taking the time to do such a detailed step by step write up. The end heatshrink under the jst wires, is that just a strip of heatshrink covering the end held in place by the final wrap or goes all the way around the length of the cells?

I want to start going off road so decided on a mid motor conversion, I picked up a Carrera Vulcan on sale. ----To add to the challenge when this build is complete I don't want to see any wires !! I think I have achieved that. I decided to go for a 250w GSM mid motor from Woosh since I already...

This one's only about a fiver but don't know if it lights up so maybe no good for commuting in the dark https://www.ebay.co.uk/itm/FTNC-Headset-Stem-Top-Cap-Waterproof-Digital-Watch-Clock-MTB-Commuter-Road-Bike/232551137011?hash=item362520bef3:m:m6L-oBwGYw7LhzJ9xJbQypQ:rk:3:pf:0

Nealh, You've just answered the problem I had when wiring my packs together for my Speedict. I did not kow the packs had to be put in series only one way round and blew a couple of plugs to bits until I realized, however I still did not know why that was the case, but now you've answered that.

I like the little compact LCD on it.

Thanks for a great write-up, just ordered a couple of those bms's. For some reason I thought you couldn't put Lipo's on a 'normal' BMS but will be giving it a go now. Now need one of those hot glue things from Aldi next time I see them in there.

Which BMS's did you get to use with your graphene lipo's? I could do with a couple for those same lipo's

The BC168 is a good one. https://www.ebay.co.uk/itm/BC168-RC-Model-Super-Speed-Li-ion-Li-Polymer-Li-Fe-Hobby-Balance-Charger-BC016/253389849041?epid=1453722229&hash=item3aff3641d1:g:peAAAOSwwZtaatub:rk:11:pf:0

I've got forks like those and they do fine for road potholes and speedbumps and the like. Some spray like this will keep them smooth. https://www.evanscycles.com/fenwicks-suspension-lube-spray-EV166637

These are only about 70mm dia but the large version of this is about 220mm long and will fit 30 cells in, the smaller version is about 170mm and will fit 20 cells in, but not a bms in either unless it's very small and can lay in the top spare space of about 25mm spare...

+1 for the sports direct hivis work jacket, it's great even down to minus temp's. I'm on my second. Very warm,waterproof, visible but non-breathable. https://www.sportsdirect.com/dunlop-hi-vis-bomber-jacket-mens-634001?colcode=63400113

Just found a new feature in the pre-release app apk download which appears to enable the battery to text you alerts to another mobile. This is not mentioned in the instructions yet though and I cannot test it at the moment as the mobile I use for it can't take a sim-card. A battery that texts...

You won't go far wrong with this. https://www.ebay.co.uk/itm/3000LM-XM-L2-LED-Headlight-Front-Bike-Bicycle-HeadLamp-Head-Light-18650-SET-/151628782015 Search the forum for 'new best headlight' for reviews I don't think you need to bother with cycling specific clothes for commuting on an ebike...

For 15 miles each way on road I would go for a rear hub motor instead of a crank drive, something lightweight looking like the Woosh Karoo but with full mudguards for commuting. http://wooshbikes.co.uk/?karoo

Before buying a tool, first I would check the gear inner cable is running free and smooth through the outer. - Put the bike on a stand so you can turn the crank and change to the highest gear (smallest cog), then change gear a few times by pulling the gear cable downward under the chainstay...

I got the Park tool one too when it was on sale half price. It paid for itself straight away, I adjusted 3 bikes and got smoother gear changes on all. But yes the X-tools version does look very similar and good value.

If the hanger is the problem, you could check/re-align that hanger with one of these. http://www.chainreactioncycles.com/x-tools-pro-gear-hanger-alignment-tool/rp-prod122319

I push the wire towards the plug and stick a pin down the back of the connector pin into the tiny hole there. Once the pin is right in I gently pull that wire and hopefully it should come out. The barb which was holding it will probably need pulling out a bit. Which crimper for these tiny...
