The cells likely as you suspect are China branded and may well be quite decent, you will have to keep us updated with their performance. They may well last as well as some branded ones of similar spec, my 36v 13ah Sam 26F lost about 25/30% capacity after 2 years.

LG cells are not 29e or 35e these are Samsung.

Don't knowif this helps any more. http://fixedgeargallery.com/articles/grahamwebster/TECHNICAL_ARTICLE_SRAM_P5.pdf

The Yellow bit on the axle end hides an adjustment for a spring I think, whether this has any bearing on your issue I don't know. On Cycling UK forum there is a very knowledgeable chap by the name of Brucey who seems to be good with most hub gear issues, you could try there.

Bonzer Skip a great find and link. Price is very good for Bafang kit and everything you need with choices for display and PAS options. Looks like the G020 is the SWXO2. Controller likely to be 13-15a. The other option it to go KT controller (where you can get up to 25a current and option of...

If opening the pack it is worth checking the 10 cell group voltages to see how they fair. If balance is out then you can even them up and then see if the BMS and pack behaves better.

40.8v could mean the battery isn't balanced, cells that loose capacity should be able to hold full voltage. Though when a current is applied voltage drops quickly.

From the battery link I would say that no name China cells are used, likely that even your one try out run at 1000w setting will have caused cell damage as they would have been at their max limit. Battery is stated as for 250-360w output only. Sellers who use branded cells usually make appoint...

It doesn't matter what the cyclist did or did not do, it would have been wrong any way.

Also if the chain hasn't got one get a chain link added to make chain removable.

I don't think there is away to deal with them when their ranting like looney, as we know not the first time someone has moaned. Some expect unreasonably something that is not reasonable. Keeping your cool and putting the phone down is likely the best route in hope they may ring back when they...

I expect the battery is only using poor medocre China brand cells rather then genuine branded ones. As VFR has said a battery link please. The cells aren't solder but spot welded using nickel or steel plated nickel so not easy to repair, if you don't already have the equipment. Soldering is a...

This appeared on CUK forum a few days ago, the cyclist was deemed 50% liable as he failed to avoid hitting a Zombie with her face stuck in a her face. Yet he sent out enough warning signals, the law is an ass. If it was a car that hit her nothing would have happened.

Electric ones are not illegal to sell, only to use in a public place. It is up to the user to abide by local traffic laws/usage. If they were limited to 4mph/ 6kmh then they would be legal I believe but then sellers wouldn't sell many.

BBS01 will blow if gearing is too high especially on hills or off road at slow speed, be warned. Select your gearing to suit you needs, if necessary fit a double to the front. Expect chain line to be out and not all gears to be useable due to cross chaining but worth a look and see. Double...

All parts you talk of will be Chinese in origin. UK outlets will not generally cater for these high output no legal parts/builds. There is one though Frank aka Xipibikes. https://www.hi-powercycles.biz/

I should have also mentioned a saggy battery will show it self up better in lower PAS levels where current demand is less. My 5 year old 29E 36v cells are saggy, ok to use in PAS 1 or 2 and can still manage 30+ miles. Use PAS 3 or more they sag badly and range in PAS3 is only about 18 miles. I...

It's got a tiddly one Flecc.

It will be legal if you can get it registered, insured , wear a helmet etc,etc otherwise no use unless you have a licence.

The controller might be a dual voltage model, if it is only a 48v one then you will have to use a 13s/48v battery otherwise you will be hitting the LVC of 40v very early on if you use a 36v battery.
