Looking to replace the original Barient 25 double speed primary winches on my
1980 C 34 over the off season with similar sized self-tailing ones. Anyone
with a similar boat find a good replacement with same or similar mounting holes
that would save me some work? Really interested in what others
1 AH means you get one amp for one hour.
Power is amps times volts, so 1 amp at 12 volts is half as much power as 1 amp
at 24 volts.
Amp-hours only makes sense when comparing batteries of the same voltage,
watt-hours is the same across all voltages.
A 225 AH 12 volt lead acid battery an 8D
Yes technically you're losing capacity but when you figure that with a standard
lead acid is best to avoid discharge below 50% to prevent damage - the lithium
actually gives you more USABLE capacity. Of course you have the lighter weight
and higher charge rate of the lithium as additional

Oh!
For some reason, I thought Ah were constant, regardless of voltage - I
guess maybe that is Kilowatts -
So with a 200 Ah Lifepo battery vs a 255 AGM, looks like I will lose some
capacity, unless that is made up with efficiency from the Lithium - .
Does that make sense?
Thanks Joe.
