    Thoughts on LiFePO Batteries

    I recently received a free LiFePo 12v battery that is advertised for motorcycles and Jet Skis. Specs: 12V, 8Ah, 480A with a smart battery management system (meaning it can charge off of the host electrical system, no need for special charger). The battery weights less than two pounds and looks...

    Battery Problems - 2016 Sea Doo Spark 2 Up

    Hey, I purchased a brand new battery for my spark. I used the battery once without problems. After two weeks of not using the machine the battery no longer turns over. I have had the battery connected to a tender ever since. The only way I can get the battery to turn over is when I have it...

    2004 3D RFI running slow and losing charge

    Hi all, I am the proud new owner of a pair of 2004 3D's and have been loving them. They are in great shape and fire right up but one of them runs quite a bit slower than the other, and the battery isn't holding charge. I was hoping replacing the battery would help, but still have the same...

    Hey guys. New to the forum and looking forward to learning. I have a 2001 GTX carb model with the 951. My son-in-law recently took it out and, after 1 run, discovered the battery was dead. When I got it home, I discovered the running voltage was 12.1 volts. After doing some research, I...

    I just bought 2 PWC last week. A 1993 GTX and a 1996 SP. The SP starts to crank the second the battery is connected even without the safety switch pressed in. If I push the start button it will fire right up but then won’t shut off until I disconnect the battery or the battery dies. I also...

    12 volt warning then battery dies 2004 gtx sc

    My 2004 gtx sc gave a low 12 volt warning then ran out of battery. I replaced the battery then got the warning a couple hours later, then battery died a bit later. Any ideas on what this could be? Wiring appears to have little or no corrosion around it.

    Rotax engine cranks over without plugs, but when plugs are in it has a hard time.

    I have a 95 seadoo xp My jet ski is cracking fine withour plugs in them, when I put plugs the starter has a really hard time to crank over.

    97 Sea-Doo GSX with very quick battery drain

    Hi, I recently bought a 1997 Sea-Doo GSX. It didn't run and had been sitting for a while. We put on a new starter and a new battery and got it to start for a bit. About a week later we went back to it and it wouldn't start. Tracked the problem down to a bad ignition coil. While we were at it, we...

    2008 Seadoo GTI Fault Codes (P0261, P0264, P0267)

    Hello - each time I ride my 2008 Sea-Doo GTI 130, after about an hour of riding I get injector short to ground codes (P0261, P0264, P0267). However, nothing happens to the skis performance. It doesn't sputter, cutoff, or misfire. I find it odd that it takes so much time for the codes to occur...

    96 GSX and GTX - Batteries Die

    [I apologize if this topic has been covered ad nauseum, but I tried searching on "96 GSX Dead Battery" and the search stripped out "96" and "GSX" because they are too short to be used as search terms and I ended up with 10+ pages of posts to slog through. I spent 20 minutes doing that and now...

    So I went to go riding and my battery totally dead. Never happened before. I did have a stereo installed awhile back. But this didn’t cause it as I’ve left it sitting 2 weeks before and was fine. Yes everything was shut off and not left on. But I did notice something. The battery must have...
