If water has caused shorting out on reconnection or the plug inserted incorrectly and then power on, the high will mean one has fried the motor halls.

One needs the battery storage to run some off grid so a 6000kwh battery should cope with a few days bleak weather, all about doing the sums to see what may work and how many panels to keep said battery ticking over at above 60% imv. A 40w panel is never going to be enough for somthing drawing...

My 252L chest freezer is A+ rated and uses 248 kw/h p.a. or 20.6 kw/h per month. That alone accounts for approx 10% of the leccy used p.a. My smaller freezer I will have to see if I can work out as well as the TD and WM usage.

1080wh is only 45ah assumming a 24v set up. One needs to work out the daily take the white goods will use. My pair of freezers are in the garage and I have been pondering (as they are some of the the larger powerusers in the house on a constant daily basis) in an off grid battery array soley...

Quite surprised by the sudden news. After seeing pics of QE2 this week meeting the new PM, she was lokking very frail. Obviously she was frailer then any one but the close circle of family and those in the know knew. R.I.P QE2.

You are correct, it is the 12 spd eagles and so forth that use a different spline carrier.

No one sells only hubs built in to rims in the UK. Nearly all Bafang hubs/wheels will be from China, unless something comes up on ebay. 11t cassette no, one will have to use a 10t cassette on a std splined hub carrier. A built wheel is usally exp and adds considerably to p&p form china so...

I understand now. No if the hub motor has six hall wires, the optional speed sensor connector remains unconnected. The optional speed sensor connector is for an external sensor and spoke magnet, these are handy should the internal speed sensing fails.

Possible wrong hall sesnore fitted or orientated incorrectly. One could disconnect the hub motor sensor speed sensor wire and use an external sensor and spoke magnet, simply wire the three wires to the hall connector plug at the controller.

I would first check all cell groups to see what the 13 seperate voltages read and then go from there, if all the same I would likely think the BMS is at fault.

Yes, the 5v and Gnd use a common rail supply. Also you can't count or it is a typo, rear hub has 6 thin sensor wires. One assumes the controller Hall connector is missing the White signal wire.

Pleased thye sorted out the issue and got yhere in the end. Did the duff battery havr to go back or did you get to keep it ?

Stick to 1x as nipple angle will be better, to much nipple angle can cause spoke failure at the nipple. Use sapim strong 14g spokes which have a 13g J bend.

I read a lot on endless sphere about batteries and safety.

4 -5 times aweek is OCD.

Eye sight retest should be a compulsory factor with any licence renewal every 10 years not just as one reaches retirement age.

If the phases are getting that hot and melting, then there is a bottle neck of current at the joint, it also may be down to the riding style/speed one rides at or the topography. It may be simply the controller and time to replace it, does it feel like a hot potato at times ?

With diy or hub motor bikes it pays to be able to do the work your self. Soldering skills are a must and one can pick them up through practice quite easily.

pedelecforum.de is the german one. Endless Sphere is the US one, both are much larger then this one and are highly techinical in a lot of the content.
