The scoot is apart right now (I awaiting some new silicon hose that takes FOREVER to arrive) once I get it all back together I'll put the meter to it, but by that time your answer from whichever manufacturer you sent it to will probably show up by carrier pigeon!   |

COOL, also take some pics of that magic battery in there and which one do you have in there?

Ok oop, it's the LFX14A4-BS12 and as I type this I'm tossing it in the air like a Baseball. Next to it is an Odyssey PC310 (that I stupidly let my alarm run down and kill) and it feels like....well lead. It's really bizarre holding them in each hand as one weighs so much more than the others. BTW, it's 14 amps and 210 CCA. I'll see if I can locate a picture. (Gremlin's got my camera somewhere  ) |

Well like I expected I emailed THREE folks and NADA, that battery is from JAPAN, now of course china could be making them for all we know(HAHA).
But everything I have looked up and read NOT ONE mentions the CONSTANT charging effect from an R/R on a scoot. And the R/R puts out quite a bit to charge the battery between 14.5-14.7 VOLTS BRO that is why I question it. And since they mention a JUNIOR BATTERY TENDER can damage it with the constant charge because it will not go into Maintenace or Standby Mod it goes into constant charge mod. I can see the R/R smoking that sucker in a very short time. Also all they tote is the number of STARTS on a motor compared to a regular battery that looses the amps.

Got this off the net. The little gray rectangle in the center of the battery is the flap that covers the charging receptacle.  |

HAHAHAHA, but you don't need that flap right The R/R is charging it  Alleyoop |

It's for use with their charging unit outside of the bike. BTW, this is what it says on the back
"Standard lead/acid chargers may be used.
However, chargers with high voltage
"desulfation mode" may NOT be used under any
circumstances. Maxcharge rate (A) is listed on
battery front label"
(max charge rate of 14 A)

Hey oop, you were RIGHT! On the bottom of the battery it says "Designed in Japan. Assembled in China!  (I still think there is enough "Play" in the voltage as long as the juice is going out as well as coming in.) |

Alleyoop I just took a look at the instructions that came with the battery. It states: "Do not allow charge voltage in excess of 14.8 volts (std peak charge voltage = 14.4V)" So it does look like they anticipated possible higher current levels and made "room" for them. This being for a stationary battery being charged and not one in use and "on the go". |

Yea well you know just about everything is made in china now a days. It may be a company in japan that designed the part but money talks and they go where the labor is dirt cheap. But you see the suspicious mind I have and I have been around the block thousands of times, if they say a regular charger can charge it then WHY the special Balancing hookup and a Balancing Charger is needed. See what I mean something is just not kosher they are not telling the whole story. Especially if they say a JUNIOR BATTERY TENDER can damage it.
I mean it sounds to good to be true that the days of having a scoot battery not having enough amps to turn the motor over fast enough are over. But I still think there is a slight problem on the charging side from the scoots R/R.
So I am not just about to go and buy one, not that I need one anyhow. But just trying to get some of the Electricals Gurus brains ticking(HAHA).

Ok, they have a number for a Shorai branch in Sunnyvale. I'm gonna call during business hours and see if I can get the scoop.

You could always go with any of the red lego bricks here: www.amazon.com/s/ref=sr_nr_i_2?rh=k%3Ali+battery+4+cell+12v%2Ci%3Aautomotive&keywords=li+battery+4+cell+12v&ie=UTF8&qid=1383805880They seem to work fine! The 4 cell might be on the small side for a scooter, but the 8 cell and up work wonders on any sub 150cc. Also, cells are 3,3V, meaning 4 cell battery loads 13,2V. Since they're fast charging, voltage drops lower than with Lead Acid. BMS on battery chops voltage charge, meaning if the charge voltage is too high, it'll only send small fractions of the charging wave to the battery for slow charging, and blocks current the rest of the wave. Scoot will be running the same as if the battery was disconnected, which would be the same as if the scoot was running normal. |

Good description. They DO look like legos don't they?

That LFX14A4-BS12 battery does not have a BMS, the special charger is the BMS. If you allow that battery to be charged by the poles rather than the charging port, you will experience what I did with my first set of LiFePO4 (I posted it above). One of the cells will eventually become unbalanced, causing either the other cells to overcharge, or the battery to never really reach full charge. I didn't take the advice of others in the electric bicycle forums who told me this was what would happen, and it did happen to me (over $500 learning experience).
Maybe your experience will be different, an ebike drains the battery below 50%, starting a scooter shouldn't drain it that much. If you use the special charger weekly, it may work, considering your not normally draining your battery too far with a normal start on a tuned up scooter.
