    Hello guys, sometimes my prius battery indicator will go down to 1 bar. Ive looked online, and the lowest Ive ever seen it online is 2 bars which seems normal (40% SoC). Why does mine go down to 1?

    Is it the original battery? Mine did that when it got weak. It surprised me!
    And it would quickly charge fully, almost to the 2 tabs that indicate the terminals.

    Time for a Sodium Ion Battery Pack!

    Yes, its the original battery that has about 350k miles on it.

    I heard about that pack, I wonder how much better it is vs the standard NMH battery

    I'm running it, it's GREAT!
    Very light, easy to install. It hold the charge much longer. You can run in EV longer than
    the oem battery.
