    anyone remember the name of the bike tubes that can 'unhook'

    I remember a discussion about them on E-S. They're bike tubes which instead of being a closed circle, can 'unhook' around the valve stem. Miles? :lol: Cheers!

    Charging 14S lico lipoly with a CC-CV 48v lifepo4 charger?

    The charger in question is from BMSBattery (King Power?) designed for 16S lifepo4, so it outputs 58.4V at up to 10A in the CV mode. I'm thinking that a 14S2P pack can be made out of 2S1P 5Ah packs from Turnigy, Zippy etc from HobbyCity. I'd rather 6Ah but can't seem to find any decent priced...

    Headway 38120S condoms

    I've been thinking about the Headway cells and how to package them well for DIY packs. A few things came to mind: * having a small amount of space between cells is a good idea for airflow and mechanical isolation * the body of the cell is live and positive (the cell 'can'). On the negative...
