Yes, your stock charging system should charge it no problem.
According to their specs do not exceed 14.4 volts with any external charger.
BUT the 2 amps @ 15 minutes is very vague. It depends on how depleted the battery is to start off. If it is near fully charged it might not even take that long, if it is at 30% capacity it may require much longer (to bring up to 100% capacity).
The manufacturer should supply charging guidelines based upon the current state of charge (true resting voltage).
This is the starting point.
But they should also supply a table for each battery to specify charge times at different rates (2 amp, 5 amp, 10 amp, etc).
These batteries will be fine for our use as long as they have have good vibration/impact resistance.
I'll probably pick one up when my battery croaks.
I should point out that chart is from the Shorai website, but the Ballistic should be very similar.
Depends...
If you have stock charging and ride predominantly flatwater the 8 cell is fine. I would consider the 12 cell if riding surf or a total loss ski (and you ride extended periods).
Hardcore FW guys can probably get away with the 4 cell (with a backup battery).
Since the stock charging system ALWAYS charges your battery, you'll get through a day of riding just as well as through 2 weeks of riding. :biggrin:
haha good point, Im gonna order the 8-cell pretty soon. Ill report back when I get it

I need to come up with something to strap that thing down. It came with a bunch of adhesive pads to get the size up. But still.....right now, my positive battery cable is too short to just set the battery in the box without any padding.
This feels like a toy.

Yah....big thumbs down so far.
It won't start my ski under load (in the water) fully charged.
My ATP Flame needs at least 10V to start. So cranking voltage must be <10V. It also cranks for only about 20 seconds before dying completely.
However: My ground cable has a bad terminal that heated up pretty good, so there is some voltage drop there. I will fix that and try one more time.
Also, letting the battery rest for a minute and trying again, it's back up to full cranking speed. None of that is any good if it won't get above 10V under load, though.
I'll give it one more try and then it's probably going back to Shorai.

what is the resting voltage 3-4 minutes after cranking? is it still recovering (rising)?

hey matt is that the 270cca? It won't start your ski in the water? really? those flames have a new flash that is supposed to allow it to start with lower voltage. at least that is what i think i heard.

He can't reflash his Flame..... and the 10v kills the flame
Mine has 210cca. The Jetworks battery has 295cca, so it's not far off.
My Flame is a 2nd gen and not flash-able. The mere fact that it will crank for only about 20 seconds tips me off that the battery may not be strong enough for a high compression watercraft motor. (Shorai does, in fact, recommend their 24 series for PWC)
I am sure that this 210cca battery would be great for a ski with a charging system.
Like I said, I'll give it another try, then I'll try to return/exchange it or possibly sell it.

scott is running 195psi on his TL ski and it cranks it over forever when he just holds it, way longer than 20 seconds and he has the 155cca. how bad are your cables? man that seems like it is killing it way to fast.

I may be wrong, but it sounds like the cells may not be consistent after initial cycling from this particular manufacturer. Like not matched possibly? Matching isn't super important, but it makes me wonder how they are manufactured. Individual cells usually aren't that far out as to effect a rest time that much. But then again these cells are different than what we used to use in rc car racing. I had a battery sponsor and I got schooled on battery matching, but like said, I'm sure these have totally different characteristics. Just my random .02
Heh, the negative terminal was pretty bad. We'll see what happens tomorrow.

I thought the terminals themselves on the battery where kinda cheap looking myself. scott is coming over tommorrow so i will crank over his ski with his ignition off to see how long it goes before it runs flat. another buddy has one on his charging system and it works good so far. The last ride his ski did not start right away and sounded a bit slow to be turning over, then it fired up and he ran all night long. both are the 155cc batteries. Scott's ski is all perfect and nitpicked over. the other guys is good too, but I am not sure about the age and condition of his starter and cables.
