    Lithium Titanate Oxide Batteries

    Was thinking of building a Lithium Titanate Oxide (Li4Ti5O12, or LTO) pack for the Harley. Anyone here use them before?

    First time i hear about this.
    Interesting info here, although it comes from a potential reseller.

    Although here they say they have lower energy density due to 2.4 volts per cell:

    I have heard of these only because they are used for powering the Japanese-market Mitsubishi i-MIEV. Reduced range requirements and more-common DCFC infrastructure made them a good choice because the reduced range didn't matter as much, and the titanate batteries are much more tolerant of DCFC.

    How's your fast charge network? Because really that's the only solid advantage that titanate has going for it.

    They are expensive, less energy dense (by quite a large factor), and fairly heavy, but they have an excellent charge cycle life and can accept high charge/discharge rates.

    For purely local around town puttering, it could be a good choice if you have good access to Chademo or SAE CCS chargers and can implement their protocols.

    For anything further than that, not a very good choice.

    Sounds like more cons than pros. Think I will pass.
