Lipo batteries

[outfmny]

I want to replace my wet batteries to lipo, can I just swap them or would it be an issue with the charging system?

Depends on what type of charging system you have. Lots of threads on here about this process. Check my signature for the link to my journey.

I have a 2019 Chaparral 203 vortex vrx with Rotax 4 tec 1630 ACE engine, I purchased 2 lipo batteries thinking It was as simple as swapping them, but just found out that is not the case and they are not refundable so I own 2 expensive paper weights....what do you recommend me to do?

so you say that they are not just drop in batteries why is that?

Do you have a DVSR or automatic charge relay?

Please get us a picture of the voltage regulator rectifier.

Did you read my battery upgrade thread?

After having my boat for a second and full season, I found that can get about 10 miles out of my trolling motor battery, or about 6 hours of use at 1.8 mph, which is not enough for my average day of fishing which is 10-12 hours. So I was messing around with idea of replacing my trolling motor battery SLA batteries with lithium batteries, and possibly my house battery as well. I haven’t seen a thread detailing the math of LiFePo batteries, only that they are lighter, have more energy than SLA batteries, and most are super happy with them. Hopefully some of you will find the following...

I did read the thread, very informative, let me add some pics

 

[outfmny]

I wil add more pics later today since my boat is in a storage place.

I need to know why you think the LFP batteries are not compatible.

So your battery switch is just a 1, 2, or 1&2??

1, 2 and 1 and 2

1, 2 and 1 and 2

I've read that the stator may not charge them or it may overheat?

Just got to the boat, here are more pics

Is this an option?

If your alternator is a permanent magnet type and it’s like the Yamaha‘s, it’s always at full output. Can you get a picture of the voltage regulator rectifier?

Even better if you have an electrical diagram of the charging system.

That Victron, DC to DC charger basically hooks to your starter battery and then charges another battery but there’s a lot of losses associated with that and sometimes there’s a minimum amperage requirement from the alternator.

The stater, is just the stationary winding of the alternator. More than likely, your system generates three phase AC voltage and the rectifier converts it to 12 V DC and then the regulator controls how much power flows into the batteries the XS voltage and current is then shunted to ground.

By looking at the pics I've posted would you point me to the voltage regulator rectifier? Sorry about my ignorance, just trying to learn this boat.
