HYBRID LITHIUM BATTERIES


Many thanks Team OCC,

I appreciate your comprehensive consideration and most useful responses, in advance of my purchase.

For your further information, I attach the force4 chandlery link to these new batteries;

I’m most grateful for all your help and feedback, especially as my budget is tight and I endeavour to make use of my existing AGM battery bank.

Best wishes and fair winds,

I’ve been following this thread for ages and we had resolved to replace AGM’s with AGM’s. However, we have now been convinced to take the plunge and move to LiFePO. In preparation for the installers arrival I have burrowed deep into the bilges to expose the entire bank and have found one case split wide open and one blown. I expect the split one was a result of frost damage. No wonder we have been using the generator so much!

Installation starts tomorrow.

Hi Simon,

Great idea!  It will really change your cruising life for the better for a long time to come.  Hope you have done your homework so you can keep up with the installer's ideas.  I'm happy to answer and questions or concerns based on our experience.  Pls let us know how it all turns out.

What sort of system/components are you looking at Simon?

The installation.has been designed here in White Stones by Hank George whom I am sure you know. I have no electrical expertise and have been trying to grapple with the science and Hank has been very patient. Most of the components are, or will be Victron, the batteries are Blue Heron 8 x105 amp hours and we are changing our alternator regular to a modern Balmar. Our wind generator regulator is 16 years old and cannot be programmed for lithiums and I believe we are having Victron DC / DC converter so that we can still use that.

I’ll post updates as the work happens. There are many new isolators and fuses going into our circuitry too. Here’s a picture of our shattered AGM.

Hank will steer you right. Please say hello to him from me.
That’s quite a lot of AH - we only have 600 and we’re a heavy consumer… I recon Hank is trying to up-sell you!!! ;-)

Bill Balme

No he’s not upselling. The bank is currently configured as 460 Amp hours at 24 volt so he is simply occupying the existing footprint of the cells we have. But I agree we should end up with a lot more useable power.

Poor attempt at humor - Hank is a stand up guy and would only sell what he genuinely believes is required.

Bill Balme

It’s done! After 2 weeks of head scratching and digging deep into the piggy bank we now have 840 amp hours of LiFePO battery installed and a fully functioning charging system tailored to our boat’s needs and design. Thank you Hank George for your patience, oversight and ingenuity.
