Old thread, but I'm curious if this ever worked out. I like LTO cells, and some interesting ones have come on the market in recent months.
The OP asked about Kokam, and no one answered. They are an excellent manufacturer, and if I'm not mistaken are now owned by SolarEdge, and are likely making the new storage battery they market.
