Can you still operate the gear shifters with those on? Are these them...

Keep an eye on HobbyKing a couple times a week as they randomly put these on sale at half price.

I bet there is already poor quality copies in manufacture and will be on sale soon.

That device is on the same lines of idea I was thinking today. I was discharging an 18650 cell@1a and it got warm so was thinking it must be possible to use something tiny which makes a 1a load. Any electronics person know if this can be done, with resistors or something?

The middle bay got "tested"

I like the idea of having a go at this for a future project. This is a good video too, by the same guy. Anyone know where to get those triangle shaped nickel plates?

Ensure the two pairs are not tight around your fingers/hand. I used to make the mistake of thinking a nice tight fitting glove liner was needed until I realized it was restricting my circulation and making my hands worse. Now I use loose'ish liners with larger than my normal size gloves. They...

I'm just curious Nealh , do you use lipo's regularly or as your main battery power ?

Got a good tip off the guy in this video to charge the cells up to 4.2v and leave for a couple of weeks to allow the weak ones to show themselves up. Works too, I've waited a week and I have a variation of 4.09v 4.16v 4.18v 4.2v (yes 4.2v=no loss!!) Can't wait to see the capacity difference...

Spotted this whilst taking apart and I'm sure it was already loose before I pulled the tab up for the pic. Maybe this brought down the capacity of the whole battery and it would actually have been ok without this.

This is quite solid and the bottom clamp part of this unscrews, if you can find a way of screwing your lamp to it using m4x12 screws maybe. http://www.ebay.co.uk/itm/322252377125?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

A voltmeter won't be waterproof, or the cheapest solution. I've got one of these taped to my handlebars. http://www.ebay.co.uk/itm/WaterProof-Mini-DC0-100V-Voltmeter-LED-Panel-3Digital-Display-Volt-Voltage-Meter-/142059824228?var=&hash=item21136ce464:m:mMn4cvjsojj9O_UuRNY2iww

Please come back with a review, I notice it says default discharge current of 500ma but am wondering if it can discharge all 4 cells at 1amp each at the same time.

To waterproof the electronic display just tear a section of clear plastic bag to put over it and hold in place with an elastic band.

Something to wrap and protect your borg-cube when it's complete. http://www.wickes.co.uk/Proplex-Surface-Protection-Sheet-1200mm-x-2400mm/p/118670 It's like thin hollow plastic packaging sheet which cut's and bends easy but won't tear and weighs nothing.

This video discussed wiring the BMS

Is that with 12s or 13s ?

You need to get a couple of these cell monitors to plug on. http://www.ebay.co.uk/itm/RC-Lipo-Battery-Low-Voltage-Alarm-1S-8S-Buzzer-Indicator-Checker-Tester-LED-UR-/401183519955?hash=item5d6866b4d3:g:e0sAAOSwTZ1XmJgZ

Jimmy at Insat is highly regarded on this forum and will sell the best genuine cells, he could also advise you on the best ones for your application if you call first. http://www.bga-reworking.co.uk/e-bike-batteries.html
