I tin/pre-solder the nickel and the stripped bare wire, then add heat and extra solder to aid flow of solder. Using a wider flat chisel type tip is better for heat distribution then a silly pointy one.

I book marked these a couple or years ago from ES and always use them as a guide. Well worth reading the threads from start to finish with pics and illustrations. Common pack design mistakes. https://endless-sphere.com/forums/viewtopic.php?f=14&t=84412 ultimate to spot welding...

Best way to build packs for optimal best current share is to use even number of cells like you have for P groups 4, 6 or 8 etc. That way you don't have to solder or spot weld series strips to cell ends, only the P strips need spot welding and if necessary in two layers to increase ampacity flow...

Good to hear Bb, build 2 nickel bus's will have ampacity of 1.8mm2 so each series one can handle 8a optimal or 11.9a which is acceptable. Some times soldering isn't always pretty to look at but sounds like you are for sure improving the battery ampacity supply. Soldering all the way along the...

All tinkering/change takes time to get used to and the new look looks fresh and good to me.

Mini fans for heat loss.

What Wheelipete say's, 1 or 2mm longer will be good enough but to get it exact remove a good spoke and measure it.

Difference on lcd and actual controller watts output is as said due to efficacy /watts waste from hub,battery and wiring. Any wring that gets warm is inefficient and too small in mm2 size, this is bottle necking power, thicker wire is the answer. Wasted watts can also be lost from battery series...

Grease will help with anti sparking and corrosion, if need be use dialectic grease for contacts.

New posts should also be prominent at the top of the page with out having to scroll the LH Panel to find the section, though in time with familiarisation of the new layout it will come to me easier.

With a recent family history of cancer ( Mother & Sister ) originating in the colon/bowel, I today as part of the National screening programme have had a second Hospital procedure carried out over the last three weeks. The screening is automatically sent out to you once you attain 55 and could...

I read something the other day about Hi-Viz and that so many now wear them (as common place) that they tend to blend in with the surroundings due to the their over use. For my use if I wear one I wear a light weight wind proof pack-a-mac rain coat by Shimano which is a fetching bright sky blue...

My lobsters (large size) fit a bit better now after a couple of rides, they have a little give in them and am sure they will be better going forward with more use. Certainly they are toastie.

Connectors are SM 2.5mm, look on ebay for them. Available in pin count you require.

I have to confess that now a days I park my mtb after a ride and that is as clean as it may well get as next time out it will get as mucky again :eek:.

Electric brake might Chinglish for Regen, just ignore it.

Yes.

I think you may be looking at the wrong item ?

https://bmsbattery.com/controller/698-sine-wave-controller-for-09-case-controller.html This kit for Dolphin/09 case battery can be paired with any geared hub motor. Only a battery and motor is needed or a GSM drive without controller. And a speed sensor if the motor doesn't have an internal one.

Code 15 would be better for off road if the going is technical and slow. Code 13 is better for road and trail riding where speeds are bit quicker. Not forgetting best use of torque is when the motor is at 50/70% of motor winding speed.
