Best Li-Fe battery I have seen so far

Well when they blew me off, I cut open the battery to see if there was anything I could do so I seriously doubt they'd honor any warranty now.

That was the Ballastic that caught fire right? I guess these batteries just aren't cut out for us just yet. I'll be keeping my eyes open for new options though. Maybe even build my own and just not worry about trying to balance the cells.

Well that sucks for you and I'm glad you caught it in time but there are the two biggest problems with that setup; run em down and they die, overcharge and they die.

My 9 lb Deka's are still going strong and still looking like the best deal out there.

I have ran my shorai dead twice and it comes back to life good as new. If it did happen to stop working i would go buy another one too. A season of 10lbs less weight is worth 160$ and i would never go back.

What are you going to run with 4.2 Ah? :dunno:
That's not nearly enough imho.

The little Shorai LFX14 series has 14 Ah.
A Jetworks battery has closer to 20 Ah

Link works fine for me.

It doesn't have CCA specs because it is an RC battery and not intended for anything else

Spec:
Capacity: 4200mAh
Voltage: 4S2P / 13.2v
Discharge: 30C Constant / 40C Burst
Max Charge Rate: 2C
Weight: 558g (including wire, plug & case)
Dimensions: 140mm x 45mm x 46mm
Balance Plug: JST-XH
Discharge Plug: 5.5mm Bullet-Connector

Well the rc batteries will probably work. One of them is nearly the weight of my shorai lfx14 though. I guess i'm partial to my shorai, have read this entire thread and don't know what to say about all you guys bad luck with them.

The Shorai LFX14 is 14 aH (eq)... I missed that too when I bought the battery.

Based on their math, their batteries have the same capacity as a 14aH lead acid but I quickly found this not to be the case. My 16 aH lead acid could go all 2-3 days while running an 800gph bilge pump 100% of the time. My 14aH Shorai could barely get me through one day of not running the bilge. Although, I'm not a big fan of Shorai right now due to my battery failure, I did like having the lightweight battery when it worked so don't think I'm trying to talk bad about them just because mine crapped out.

I agree a 4.2aH battery will not be enough for total loss but at $55 shipped to my house, I think it's worth a shot to see how long it can last. If I can get a few gallons out of it, I will get one more and run one as a reserve battery.

No harm in trying something new though if you dont mind spending the cash. Let us know how it works. You could try running one to power electronics and one to run your starter.

Same thing here on the Ballistic batteries, my ski ran fine for a couple months, now the terminals broke loose and the plastic case was cracking, I called them up and even sent the battery back to them, they told me i over tightend the terminal bolts, NO Warranty so now im screwed, Im also a dealer and have baught a couple of these batteries for customers. Never again they suck to deal with.

had to try this out saving 10lbs for under $200 i was game ,but what i found was that the ballistic battery is not up for the challenge of watercraft in a nut shell .mine lasted one day before it died without using the bilge at all.if you want to run your jet ski like an r.c. car (charging them all the time)im sure you could get a little more life out of these,but i don't want a battery thats going to be the x factor on if my day will get cut short. this is not new technology and theres a reason they are not being used widely by watercraft users.i am not going to try and analyze how these work nor do i care about the techy mumbo jumbo, but i do know what works for me ! i spent a minute on this thread and learned somethings but all in all it gave me a headache. (sorry just shooting from the hip) knowing volts cca and ah and does it start when i hit the button is all i need to know, i will leave the rest up to the engineers that are in their competitive markets to guide me .long story short is i dumped my ballistic (luckily it fits in my wifes quad which happened to need replacing or i would be out some loot) and went with jet works xc 25 at a weight of around 6 lbs i saved over 6 pounds and still have a ski that will start and i can use my bilge when i need .works for me ! good luck with the li-ion technology .

Be very careful if you run a RC LIPO battery ! if you over discharge it and then over charge it , it very well could turn into a ball of flames either charging or the next time it has to do a big discharge (start) . Something like 2.6 to 3.8 volts is the range for lipo, they don't balance well so you need a charger or a BMS ( little board that has over/under volt protection plus cell balancing )

The CCA is the C rate 4.2 amp X 30c = 126amp discharge for a few seconds . If you parallel them you get more CCAs

Have fun over.
