Whitworths have them for around $400 each but I found them online for $330 each, delivered.
My deep cycle batteries were Fullriver. I replaced these last year with Marshall 120ah. These look like they have come out of the same factory as Fullriver. One of the Fullriver batteries is now 10 years old and in my tinnie for sounder and minkota duties. The other died, but I suspect that was my fault as it was an HGL model and not suited to my application. Also I suspect not smart of me to have it paired up with th older DC model Fullriver.
The other advantage of the DC/DC charger is that I have an onboard 240v charger and just plug a lead into boat at home. This keeps my start batteries charged, and while it is on, the DC/DC charger is charging and maintaining my deep cycle batteries.
