12 cell Ballistic battery for push-button 1428cc?

Hey,

I found a guy selling a brand new 12 cell Ballistic battery. I was thinking about picking it up for my 900 project. For those that don't know it's going to be a 1428cc 13.5:1 push-button start pro-streeter.

Here is the specs on the battery.

Will this be enough battery to spin the bike over? I have compression releases on the outside two cylinder and plan on running a Honda starter for some extra oomph.

If it was me, I'd be contacting the battery manufacturer and see what they say about intended use.

I sent their tech department an e-mail, but I don't think I'll have a lot of luck.

What's the rating for the wet cell that came with the bike? I'd think a comparable dry cell(that's what the ballistic battery is) would meet the electrical needs.

"12 cell" makes me wonder what the technology is. If it was the new Li-Fe battery, it would only be a three cell to get 13V. It sounds like it would have to be some kind of Nickle type?

Concern is compatibilty with a MC charging system which forces 14V on the battery during operation. Not sure what optimum charge is for these batteries.

According to BatteryMart.com the Yuasa YB10L-A2 specs out at:
12 Volts
11 Amp Hour @10 hr rate
1.1 Ah Charge Current
160 CCA

From Ballistic's website..."Ballistic Performance Components EVO2 Batteries use custom designed lithium ferrous phosphate (LiFePO4) cells."

I'm running the same ballistic battery, wings a 10.5 motor over better than a stocker spins with stock battery. Lithium Ion battery is my understanding, 410 cca. It takes a charge from dead to full in less than 15 min. I run mine down while working on wiring the lights and starting a fresh motor, come to find out carbs needed work. I'd venture to say it would work fine on your motor but don't hold me to that. :laugh:

Ballistic tech dept. got back to me.

Here's their answer, "We recommend the 16 cell."

No justification or anything. I think that they just told me to get the largest so I'd be safe...

I just don't want to buy too small of a battery and then have to remake a battery box and hope a bigger one fits.

OK, it's Lithium Iron Phosphate which is about 3.6V/cell so it's a four cell battery. I don't know what the hell they are talking about with 12 cell and 16 cell baloney.

en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

The lithium iron phosphate (LiFePO4) battery, also called LFP battery, is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material.

Specifications

Cell voltage = min. discharge voltage = 2.8 V. Working voltage = 3.0 V – 3.3 V. Max. charge voltage = 3.6 V.

Series parallel to get the required voltage "and" amperage. IIRC the one in my 750 twin is an 8 cell.

It's like eight individual tubes glued together.

This and the shorai I think are not too different, and the word is still not out yet on these. I have that new shorai in my rex. Really cranks over quicker and strong! The downside, I have heard, is that it may charge quick but if your bike doesn´t start up quick then it drains fast. I would get whatever they recommend for the new Indians or those Hardly big bore kits. Probably the same as they told you to get. Having more than you need is not a bad thing when it comes to sure starts.
That is an adventuresome build you plan there. Keep us posted on how it works out on the street and your riding habits.

Interesting. The parallel cell thing is risky because if one cell develops a "problem" (Like an internal short) the cells in parallel will unload their full energy load into the bad cell. Methinks not what I want riding three inches beneath the family jewels..... :laugh:
