    Battery Charging Management Logic Dive Gear Genesis 600 Scooter

    Just like to know from others that have the Genesis 600 Scooter, their charging techniques.

    On the day of the dive recharging the battery = in between dives.

    Not diving the Scooter for a month or two, storage, top off etc.

    I know that Logic Dive Gear offers the below two devices for extra battery management.

    Watts-Up Meters for Recharging
    &
    Sentry DPV Dashboard

    Dont they have Li Ion batteries?
    Li Ion like to sit around with half a charge not a full charge. So charge before a dive not after.
    Once charged there is no reason to "top up" unless its been sitting for months or more.

    One of the great things about Li Ion vs other batteries is that the voltage is a good indication of state of charge. By that I mean that is as a Li Ion battery is discharged the voltage drops in a near linear fashion. ie per cell, 4.2v is charged 3.7v is +- 50% and anything bellow 3.2v is pretty flat.
    So a simple check with a volt meter will tel you the charge state.
    NiMh/NiCd and SLA has much less linear discharge curves and its harder to judge charge state by measuring voltage.

    They are li-ion. Which can be hard to leave in the mid voltage range after diving (i.e. if you don't use it as much as planned). I end up leaving the electronics plugged in for a few days to allow the circuit to draw down the battery enough to get into the storage range on mine. But I have the 1200 model and its got a huge battery.

    General rules for LiIon batteries:

    Don't store at full charge, 50% ideal but don't sweat it anything below 100% is OK.

    MUCH more important DO NOT let it fully discharge. Far better to put it away with 100% charge than 5% and come back 6 months later to find you have a brick.
