Ok they are unusual in that no printed markings. They are embossed Says Sanyo ur18650w2 Sorry but I'm not comfortable taking a lithium cell to bits ! Even a dead one !

I'm individually balancing the cells and have replaced the 3 dead ones with as close as I can get to matching

Hope this makes sense Canister with two screw off plates . One contains connector 3 x 10 cell packs wired in series to make 37v nominal These are then linked in series

Yes indeed good idea

This Never had any issues with my handbuilt wheels (by OnOne in Sheffield ) And several on my Chinese hub (front one at that)

Did you ? Oops - the sleep deprivation of having two kids under 4 dies funny things to the brain !

I took an old 6ah powabyke battery apart - suspected dead cells I was shocked to find 30 x 18650 cells with no BMS whatsoever Not suprisingly several cells were reading 0 volts The rest were all over the place Even worse - to my mind they were simply 3 x blocks of 10 cells in series Surely...

Just to confirm it worked just fine My testing was basic - I simply left both gloves on in the middle Of the concrete garage floor I just measured the voltage on my 2500 7.4v packs every 10 min till I got bored. Voltage dropped slowly - I guessed about 5 hours constant use to get down to 3.2v...

Plenty of uk kit suppliers (which I think is what you are asking for given the parts list) Try 8fun, juicy, Cyclzee, cyclrocity for starters Lipo (ie rc cells) best got from hobbyking Actually ignore me - those all have pas sensors not torque

Won't it fit on the top bar ? Looks like there are water bottle nuts there ?

They are plastic brackets with screws But I wouldn't worry - controller is 30 quid to replace and hard to remove with cutting off wires and connectors Never heard of just a controller being stolen - what's the point. No resale value in a damaged bit of niche equipment that was only 30 quid...

My controller is inside a normal plastic water bottle (cut open and tap end together again ) on a normal bottle holder Adds an element if stealth IMHO

I think OP meant the battery and basket would be removed on arrival at work Not that it would mounted there when cycling Could be wrong !

180w only So gutless

[q uote="flecc, post: 205197, member: 3"]I'm another who switched to the New Posts option some while ago to avoid missing anything and also so I didn't have to search all the other forums individually. Personally I've always preferred almost everything lumped together in one forum in a moderate...

My tuppence Totally agree with d8veh - you'd be a fool not to ! Having said that I would rate a hobbyking accucel 6 over the IMAX b6 . They are nigh on identical in everyway except the accucel has active fan to cool and the IMAX relies on passive fins. The IMAX gets very hot and my accucel...

Yes indeed just buy non matika branded packs. They often at least as good. And don't have the chip as it represents a pointless cost - y

It's neither. The chip in the BMS simply shuts down whole BMS permanently after 5 failed charges (for whatever reason) There is no way to reset that chip , once it decides the pack is dead is nothing you can do to change its mind So you can find duff cell and replace it but the BMS will...

ok so this is not actually fixed to an ebike in this instance but no reason it couldnt be Although aruguements of legality and "grey" areas of law are likely to be fewer than the usual 250w/15mph/thottle stuff And it they are not fewer , they will most certainly be shorter argue with this I...

Well I'm on my 3rd version of the 11.1v booster having started with a 7.4v one Works a treat ! I just keep rebiulding packs as I harvest better 18650 cells (or do something silly like the time I plugged it in backwards!)
