    for those in the US looking for standalone options, again they all say not to use in series or parallel....

    Re: Changing to Lithuim Scooter Batteries

    I own two scooters, one Divertug V-IV 800 with more than 5 hours of cruise time, and a humble AV-1 apollo, which is the one that I am looking the Lithium battery for.


    The AV-1 when used with the saddle is really fast and very funny to opérate with. Also I use to give it my dive buddies that do not have a scooter.

    After doing some internet research and considering reliability, I went for Ping pack for my old Sierra. Not the highest energy density, but appears to be reliable, with 90min burn time than NiMH (50% more) and faster due to the 2V increase from LiFePO4 cells.

    We got some SS bands bent to mount the pack and routed the wiring as best as could be. The fit is tight, and we removed the lower retaining ring in the nose, and put a rubber bumper inside the end of the nose instead.

    Hi
    Which ping battery did you use for your sierra?
    Can I have the dimensions/specifications for the battery?

    I got the 24V 15A 135x105x140mm battery. The larger capacities will not fit unless you don't re-use the same bulkhead and seal.

    I also asked for PP75 for the discharge leads (I crimped myself as they need to be passed through the bulkhead sealing gland). I also asked for PP15 connection for the charge leads instead of XLR, and an upgrade to 6A charger. After an hour's scootering, the 6A will bring it to full charge in about 1.5 hours, so one battery can easily be used for 4 scooter dives a day.

    The LiFePO4 is about 26V during use, compared to 23.5V for the NiMH. The motor and electronics get hotter, but we easily pull ahead of all the other Sierras and Echos.

    Hello,

    I got also one Divertug V-IV 800. How did you replace the original battery by Lithium battery ? Do you have somme pictures ?

    Thanks

    Hi,

    Be aware that I was talking about replacing the lead acid battery in my Apollo DPV.

    The Divertug already has a Li-ion battery, and it is a very powerful one: I have been using it since six years ago, and still delivering 5+ hours of burntime at cruise speed.

    If for any reason you want to have an additional Li-ion battery on your Divertug, I wold suggest to contact them through their webpage, they have been always very responsive:
