The 19 cell conversion post here got me curious to learn more. Looks like a very simple, drop-in conversion. Almost too god to be true, mainly because there is no BMS. Can someone care to educate me about why such a battery would work in the long term (i.e., why would it not get out of balance and cry some individual cells)? I understand it relies on a version of the Laird's software, but that is applied to the entire pack and there is no control on individual cells. So what's stopping that conversion from going out of balance over time?
Also, would combining the Leaf modules with the idea of parallel NiMh cells for top balancing work? I don't see why not, if it works with the Panasonic cells.
Looks like there is a source in the US that sells new Nissan leaf modules for a bit over $100 each. That would be a roughly $2,000 conversion. Or a set of modules may become available from scrapped Leafs eventually. I am tempted at this price, as it would give the Vectrix a really useful range for me.
