Looking for a light weight battery.I have no extra battery needs other than the motor,no stereo or big lights etc...what is the smallest CCA that will support a 225 promax?needing to cut weight,I`v been on weight watchers myself!

Look at the Odyssey's. A little pricey but compact.
I run the PC925 Odyssey batts in 3 sxs machines. I would think they would handle cranking a 225 ProMax. They crank stroked bored V-Twin Kawasaki engines 12.5:1 compression and WAY harder to crank than stock now on a single battery.
Warning though: The last two I have bought were not as good quality as the prior 4. I run 2 per machine.(one for backup as they take some CCA to crank the big V-Twins) Not sure if that has been sorted or not, it has been about 6 months since I got the last two. When they are good they work GREAT. I use an Odyssey brand charger to charge/maintain them.
Baja is on it with the 925 responce. I crank a 300X with it-keep it hot with their charger as he indicated as well.

I use pc 925 for my 2.4 200 running an electric pump , stereo and gps never had a problem.
They are a good cranking battery and deep cycle all in one.
Another vote for the PC925 Odyssey

Nice setup Tony.
I am not sure where you get your hold downs but FuelUTV makes a mount for a single PC925 for Kawasaki Teryx 4 that would be perfect for a boat and light weight and actually looks very similar to what you are using. It is held down by 4 screws and you could seal the holes and put some rubber washers under it to dampen vibs. It has a metal bracket that goes across the top and holds the battery nice and tight.

I run the Odyssey PC680 on my 200XS twin engine set up. Always figured I could pair them up if needed for starting and have never needed to. A single PC680 starts a 200XS with no problem.
Running the same battery in my airplane and it cranks over a 360 cubic inch high compression four cylinder Lycoming no problem. Also run them in my motorcycles cranking hi compression Harley's.
I havent had a problem with the quality control on the Odyssey batteries and hope it doesn't start. Optima's used to be a great battery then the quality went to crap leaving me stranded a couple of times in the boat. Won't even consider an Optima again.
Looked into Braille batteries. Light weight with high cranking capacities but a lot more pricey. Found Odyssey didn't make a battery to fit one of my bikes so while researching Braille batteries discovered they are made by Dekka. Found one to fit correctly and works like a champ. Read somewhere that Braille picks the batteries that test the best of the line and put the Braille sticker on them.
Odyssey, Braille and Dekka are AGM construction batteries and can be mounted in any position without leakage.
What is the cost of these batteries? I just bought a small battery for a 172 (150 HP) and the cost was 300 bucks! Time to look in another direction.
The Odyssey PC680 runs $100-135 depending on where you find them. The Dekka's run in the same range. The Braille are crazy expensive.
I looked these batteries up on the internet. Some of them have metal jackets. Would they be considered maintenance free batteries? They look like the perfect answer for aircraft though probably not FAA approved. I am about fed up with FAA/government approved ****!
I have never gotten a 925 + shipping for less than about 150 to my door. They are AGM sealed batteries, but they need an AGM charger because they peak at higher voltage than lead acid batteries. They also take vibrations WAY better than Lead acid batteries that fail over time in high vibration environments. I went through a few stock lead acid batteries on my side by sides before I started running the 925's and have never looked back. I run them on their side in the mounts I use from FuelUTV.
I was not bull****ting about some of the 925's being better than others. My buddy who bought a 2013 T4 from me has a bad 925 in it right now. SO far we have gotten 3 bad ones between us. One bad from jump street, two that took a while to show they were not as good as the rest. They all peak within .1 of each other from day one, it takes a while to know what you have for sure.
First indication is when you get back from a ride and go to peak them, they peak a lot faster than the good ones, at least on the Odyssey charger. If you know you put a dent on the charge and they say fully charged in 15 minutes, they are on the way out, (no matter what the ending fully charged voltage is!! It will be the same as your good ones!!!) watch out.
It should take 30-45 minutes or so at least on the Odyssey charger I am using after I crank a bunch of times on them for the really hot and good ones to fully peak.
The Odyssey charger will go through charge wait charge wait charge wait indefinitely once they peak then drop and it may seem like you are reviving a bad one, but it just won't happen sadly even if you leave them doing the loop for a week, just not going to happen.
I get away with an Odyssey PC625 on a S3000 drag (16amp charge) with Weldon 2015 pump.gotta keep her charged after every outtting tho
How long are you going to be running for?
You mean you've gotten away with it so far....:nonod: The ecu does compensate for lower voltage to an extent so I would imagine thats the only reason you haven't destroyed the motor. A 625 is adequate to run your trim and thats about it.Quote:

Sounds like a lot of fun. Hell yea!Quote:

You could probably get by with less than 10 pounds a pack and at the size they are, you could carry an extra pack with you for a backup. I have always wondered why Li-Po technology has not made it to boats yet.
will a merc ob charge a lithium ion battery? i heard somein about a special charger needed?????? ANYONE?
yup special charger needed.My Merc wont charge them.contact Rich Srnec on here for the Li_po and chargersQuote:

I spent $400 on a stark battery and refuse to put in my boat.. not to mention they list amp ratings that are way off
http://federalbatteries.com.au/batteries/
Go here and you will find all the specs on all Federal batteries including the odyssey and Deka.
Take a look at the http://federalbatteries.com.au/AUX14/ you will need two. Remember the CCA and the reserve capacity is X 2 when you use two in parallel.
Thy are used as auxiliary batters in BMW and Mercedes.
Thy are 8lbs each.........:)
http://www.batteriesasap.com/aux14.html you can get them here cheep.....
Be careful running that **** in your boat
Lithium cannot be extinguished if a fire breaks out.
It is a AMG same as the odyssey no lithium in it.
It is a lead acid batt.
No special charger needed.
Will charge just like any other batt.
Run LiPo and LiFe in my RC boats know all about them and what thy can do. have a special bag to charge them in.
At 200 CCA and 170 amp reserve capacity ,X2= 400 CCA and 320 reserve capacity at 16Lbs. for about $150
Glenn, Will you elaborate on issues and ratings?
The PC625 will work with stock compression.
13 lbs.

The AUX-14 I found on this sight as I checked every batt thy listed.
The nice thing is you can fit two of them in a U1 batt box.
This way you will have the option for a 24V 200amp 170amp reserve power source for the fast trim up if you want.
All at 16lbs....................All charged off a 16 amp eng stator system.
This is what I am doing on my boat build.
With a 340amp reserve you should be able to run all the toys you want on the boat and 400 CCA should crank the best of them over.
Has anyone tried the anti-gravity batts??? About the same specs as the oddesy's 1/4 the weight x2 the cost. I was thinking about trying them.
yepper,i have used even with 225PSI cranking at races.use at river all day with 180PSI and never had prob..even with Weldon 2015..on 16 amp stator..granted it gets charged every night after use.think they go for $140.00?Quote:

Check this out let me know what you all think
I've been using them for almost the last 2 years. Work great. 24 cell for starting and 8 cell for 24 volt trimQuote:

Also another guy on here had lifepo in his liberator I think he goes by JPF something and the batteries swelled. Lastly my friend had his hyabusa catch fire from oneQuote:

The only issue that we have had is that if one of the cells gets over charged the circuit board will shut the battery down and it will act dead even though it is actually overcharged then you have to wait for it to gas off and it is ready to go (they are very voltage sensitive). These batteries will extinguish with a standard extinguisher and are very light but they are pricy. Brent's issue was alternator related and allowed voltage to back feed to his electronics. The battery tested fine when it was sent back to Kevin. The circuit board does nothing other then shut the battery down if a cell registers too high. I am running one of these in my river rocket and have one in my car. I am not and don't claim to be a battery expert but Kevin is and he will answer any questions that you might have. The nice thing about these aside from the weight is that that they have tremendous stereo powering capability and they don't loose charge when they sit for extended time like a standard battery. The oddessy is great if you are just wanting to start and go.Quote:
