    Lithium Batteries Shipping Rules Discussions

    Does anyone have any information regarding the situation shipping in a container via sea ? Yes it takes a lot of cells to make this workout but if one could get the required number of cells together, how difficult is it to ship via container shipping on a ship?

    Yes I thought about that and checked - it is not conductive. There is another filament that sounds interesting - good reviews at least. Its a Carbon Fiber Polycarbonate composite. Sounds to be the best of both worlds and is a little more economical -...

    This just jumped out at me.....150c heatbed ??? Where is such a printer ? Highest I have seen is 120c but enclosed.

    Your project has plunged me into the world of 3D printers ! I am very keen to print battery cases and make up battery packs using your system. Having spent the last week using most available hours to study 3D printing, I am getting up to speed on 3D printing. Have you considered NylonX filament...

    hmm, its going to be quite the adventure then. I would think it takes a lot of skill to solder parts to a PCB and get a nice job. Well, not to worry, no pain - no gain.

    Open source BMS for 48V to 400V lithium-ion battery pack

    Would be really great if we could get hold of the IC needed for 15s/18s. How difficult are they to procure? How big of a change of setup is it to the PCB/system to change over to the better IC ? If I understand this correctly, the PCB's are made from a Gerber file which is sent to a place that...

    Open source BMS for 48V to 400V lithium-ion battery pack

    Nice project here ! I am curious though as to why 12S and not 14S? Is it a massive undertaking to have a 14S version ? maybe some technical limit in the parts used? *Edit* Ahhh, I see, the IC is the limiting factor. Any idea of when the newer IC will be available so it can go all the way to 18S ?
