OPzV Batteries

[clamshack]

Has anybody tried a bank of OPzV batteries on their boat? I read about them, recently, in a Victron document and they seem to have some advantages. Would love to hear if anyone has any experience with them.

I am fan of gel batteries having experienced great life on good quality 12v gel batteries on previous yachts despite considerable abuse.

The 2v cells are reportedly considerably better again for deep cycle applications. I tried to order these with my current yacht, but logistics prevented the purchase going through.

Nowadays these batteries face heavy competition from lithium. There are advantages to lithium, but for KISS and reliability the 2v gel batteries still have appeal.

Dashew fitted these to his FPV series so you might find some information from this source.

If you do install them keep us informed.

2 volt OPzV and OPzS batteries are excellent for deep cycle applications. You can also get them in AGM but I'm not sure why you'd want to. I used those in a land-based application, but if you want to learn about them on boats then contact "klee wyck" who used them in his trawler, if I recall right. He's on the Trawlerforum and maybe on CF as well.
