Anyone interested in the Panasonic NCR18650PD? I'm thinking maybe to get them from another supplier, who can give better price. But I need to buy something like 1500 cells lol.

oh ok too sad. I knew it wasn't your conversion but they should have let you see the factory even though production hasn't started..

How come the offering hit the stop? What happened? They didn't like your conversion?

Not sure to understand.. Overheating from battery, motor or controller? Anyway my mac motor and 12 fet controller should handle it. With such a big pack battery would barely get get warm at 1000W which is about 1C

Ideally I'd like to use epoxy glass sheet and aluminium, but it's too expensive. I've seen 4mm aluminium sheet with epoxy glass sheet shipped to france over 50gbp. Wood is free lol

I had a start on my wood box: Added plastic protection on the corner and have an area to fit a compression strap. Next is to get a carbon fiber vinyl: 1.27X0.3Meter 3D carbon fiber vinyl film/ carbon fibre sticker (50X11.8"/127X30cm) 13 color option FREESHIPPING car sticker-in Stickers from...

Why konions are safer? I've read several fire thread from them

It's a 2*9s + 2s zippy compact. I had a dead cell in one of my zippy compact, so I extracted the cell and divided the pack. They are all 4AH cells with 3 in parallel. I end up with a 74V12AH pack, which should be enough to do 20km on my 1000W continuous Brompton bike :rolleyes:

Jerry, I've seen on your signature you are now using Konion pack? As you are looking for the most lightweight setup, why don't you try these new Panasonic NCR18650PD or LG ICR18650D1 cells? They are at 230wh/kg so 2 times lighter.

Battery pack is 130x150x150mm: I'm thinking to maybe use aluminium to have to less bulky and safer in event of fire? What about 3 mm aluminium sheet I would weld?

Hello all, I'd like to create a battery box for my 74V12AH Zippy compact battery pack. I've already created a box for my A123 20AH battery. It's all wood made, quite strong but a bit bulky and not very safe: As you can see, I used 3 custom steel tie to compress the cells...

Where do you find the epoxy glass sheet for the battery case? I'm having trouble to get them at good price

Ugly bike is the best theft deterrent :cool:

Tonight, I've seen my bag has been opened by someone: But for some reason, he didn't steal anything. I wonder why :cool:

Hello all, Here is now how I secure my brompton on the street: Paris street are dangerous, this is what I use to see:

Thanks Dave. So I won't buy from BMSBattery. I have a 20s bms from Bestekpower, I'm going to plug it to my lipo and see what I get. If it's good I'll get them for this 37V pack

Since I epoxied the plastic bag frame, wobble has almost stopped :)

My next battery pack will be some LG or Samsung 230wh/kg pack. I'm waiting for some test from endlesssphere before purchase. It will divide the weight of my pack by 2 with 1000wh for only 5kg. I probably do most of the time between 20-30km. But because of the motor power, I usually use at least...

Yeah you loose the gearing. Although it doesn't matter much for me as I use motor assist 99% of the time
