Shorai lithium battery discharged to no volts

[CrackerRican]

Im thinking I may go with the EarthX batt that Sean carries. Its the only lithium batt that I've found that has the over/under voltage protection. Which I dont know why the other lithium batt. dont have if its that sensitive to voltage drop.

Me either. I will put a switch on the the usb port, & I'm still swapping out older style r/r for R1 style. The the shorai battery will only charge to 6.8 volts, & as soon I take off the charger it discharges to 0.

You guys using the pc680 battery, whats the spec on it, cca

The Odyssey PC680 has 520 HCA for 5 seconds and 170 CCA:

Personally, I'm going to buy a 22 Ah/420 CCA UB12220 if my current UB12180 (18 Ah - 283 CCA) ever dies (it's over 7 years old now and still going strong):

I don't drag race my max so I don't see any reason to spend the extra $100 or so on a light weight battery.

That is a great price, will that fit in the batt box without mod the box

 

[DMAN999]

Yes it will.
It's the same size as my current UB12180 but has higher Ah and CCA.

 

[CrackerRican]

Yeah I like that 420 cca, I'll do more research on it when I get home. Its hard to do it on this tiny phone. Thanks Dennisunk:

 

[DMAN999]

You're welcome.
I know at least a few guys here have bought the UB12220 and are happy with it.

Let us know how you like it after you get it installed.

PS
I posted pictures of how I had to bend the ends of the battery cables to work with mine:

Yes it can, because your USB device works off of 5 volts. Your bike runs on 12 volts, so you need a voltage converter to bring it down, (that little black box connected in line with the MiniUSB connector). If that's connected to a non-switched connection to the battery, it will slowly drain it without the engine / alternator running.

Good information to know....thanks! :worthy:

Your right, their finicky and expensive, I also did the R/R change to a Mosfet.
The main thing Id like to say about Shorai is that when I called to explain the problem,
that by the way I caused, the rep said in our conversation that a new battery was "in the air to me" as we spoke.
I was told to pick-up a prepaid label from Fed-ex and send back the bad one' two days later I had a new one. Excellent Service!!!!
They are weird about the complete discharge but Iv seen the "come back" after a discharge
and perform as normal.
I suppose it would be up to you as to weather or not you'd be apt to trust it after that.

Well I finally found some time & installed the UB12220 & R1 R/R that I got off of Jagco1. Man 14.5 vdc, haven't seen those numbers in a while. Hopefully this batt will last me 10yrs.

nice !!

Man don't be lazy. You can do better than that. Your bike deserves a better RR bracket

Yeah I know, it's just a temp so I could get it running again. I didn't have a whole lot of time to be creative. Now that I got it running again I have more time to get my juice flowing

Looks great Larry, I mounted mine a little farther forward on to the plastic panels for the stock electrics. I'm not a 100% happy with where it is so I may add that to winter mods list, at least mount it a little more professionally. I hate having a empty mounting hole!
