    i was wondering when this would catch on (balance chargers). I play with RC cars and helis and wondered how everyone was getting by just hooking them up to chargers without regards to the cells.

    I wonder if my RC charger would work on the motorcycle batteries.. not a fancy unit but will do up to 6 cells (are the connectors the same as your basic balance chargers?)?

    But Lucas many of us have them already and would benefit with a stand alone device, which is what I am asking about. Not one built into another battery.

    Would this work for example.....

    The input voltage seams good, DC in 10v - 18v, but would it be robust enough for vehicle use ...... :-)

    I'm chucking ideas about that's all.......... as I find this very interesting

    0.6 amp max is a bit weak for a vehicle. You need to get at least 1 amp into the battery. That's why Battery Tender Jrs.
    don't really bring them back from a voltage drop. Yes of course we sell them. The other balance chargers like the one Ballistic sells require hooking up to the battery terminals plus the balance port on the battery.

    These just plug right in to Shorai or any model with a balance port.

    I actually have a bunch of RC trucks and Helicopters and a nice RC balance charger, that does Lipo, LIfe, NIMH, Nicad

    How many cells are in the shorai? is there a balance plug I could use? ( My charger will balance up to 6 cells ). from .1 to 8amp charge rate.

    If I could find a balance plug, I could at least try it see if I can bring it back.
    I'm assuming I will have to charge it like a regular RC battery .. Plug the main +/- wires in, and additionally plug the balance port in ( if there is one? )

    So, from what I've seen, expect a life from 1 year to forever. My 96 CBR900RR had the original battery when we sold it about 2 years ago. Very unheard of, really. As for the Shorai and it's counterparts, the dealers I've talked to have raved about them, the forums and owners seem a bit apprehensive. I'll wait, for now.

    If you have that kind of RC charger, and just need a connector to the battery? The charger should have a variety of plug ports on it.

    Since you started this thread, I'd be happy to mail you a connector that plugs into a Shorai for just the cost of postage.

    You might be able to bring it back if your RC charger has a "Fast Charge" 5amp option. Then you run the balance.

    I have this charger http://www.amainhobbies.com/product...-Pb-Li-Ion-AC-DC-Battery-Charger-Cycler-6S-8A

    Yes it has ports on the side of it.. all my RC batteries are 2 and 3 Cell LIPO's ( not Life) anyway I have ports up to 6 Cell. How many cells are in the Shoria battery?

    Toss me a PM I'll take you up on that offer if you think it will work. Is it just a standard balance port? or something proprietary?

    I sent you a PM, Haven't seen that one. I recognize the style of connector, but definitely RC only.

    Sent you a couple pics.

    But i'm still wondering how many cells are in the shoria battery. and if I can just hook the Red and Black main wires from my charger via clamps onto the shoria battery..and use a standard balance plug from the shoria port to my charger.

    I have not pulled the battery out of my bike to inspect the port hence all the weird questions mabye it will be obvious when I yank it out.

    I can solder my own adapter if I have to. Just don't know what I need.

    Hey there, I PM'd you but basically with any of the starter batteries you are balancing only banks of three 3.3 volt cells either cylindrical or prismatic to make 13.2 at basically 2.3 amp hour. Double the cell banks in parallel and your numbers just add by 2.3 to get the amp hours. 6.9 amp hour = 3 cell banks of 4 cells, so = 12 cell battery. As I said earlier, alot of the specs of these batteries are BS.

    Well I could not resurrect my battery...its done.

    So I bought another one and the charger UGG.

    All working now! now that i have the propper charger should be fine, although I do need to figure out what is leeching power while it sits. the clock cant possibly drain that big old battery in 6 months can it?

    Anyway Super Enduro is back in action and ready for a trip this weekend freezing nuts...hopefully the snow isn't too bad lol.

    Likely some kind of electrical fault. I would get it checked or you may end up with another boat anchor for a battery.

    Now:

    First install in a KTM 990 drop in.

    Old battery as it sits in rubber tray Weight 8.6 lbs

    New battery comes with front mount terminal adapters and drops into tray with no need for spacers. Weight 2.2 lbs
    This also has the built-in BMS balance and protection circuit which is why it has a full 2 year warranty.

    You can look for the drain on the system, pull the fuses and then put them back in one at a time you will find the short if there is one causing the drain that will help you locate the circuit it is on.
