Re: Stus-List small start battery for yanmar 3hmf

[Marek Dziedzic via CnC-List]

It does not have to be that bad.

I don’t remember the source at the moment, but I have seen some calculations 
showing that if you need a large bank and you are pressed for space and weight, 
the LiFePO4 batteries can offer a decent value. As you mentioned, you need 
about half of the capacity (in Ah) (due to deeper discharge cycle), so you need 
fewer of them. They weigh less (per unit of capacity), so you have 
substantially less then half the weight. And they take substantially less room. 
They would probably cost substantially more, but they would last more 
(substantially more discharge cycles). So you may need to compare the cost to 
several sets of the lead acid batteries. From what I have read and seen, the 
biggest kicker is the charging system. You would need a new alternator, a new 
(and sophisticated) controller, a Battery Monitoring System etc. Your $2500 
investment in batteries might be just the beginning.

For anyone interested, I suggest this reading: 
http://www.pbase.com/mainecruising/lifepo4_on_boats=1. And this guy knows 
what he is talking about.

Josh,

I looked into this a bit more, and while I still think it is wrong to use 
“EqAh”, the concept is not as misleading as I originally thought.

The claim is the depth of discharge for Li-Fe batteries is 95% whereas for 
lead-acid batteries this is 50%.  In other words, a 110Ah lead-acid battery has 
only 55Ah of usable deep cycle capacity whereas a 110Ah Li-Fe battery would 
have 105Ah of usable deep cycle capacity.  This would give a 6 Ah Li-Fe battery 
12 EqAh_deep_cycle.  [at this time the largest capacity is only 12 Ah (36 EqAh) 
~$300]

For engine starting, the capacity drain at higher loads is non-linear for lead 
acid batteries due to high internal battery resistance.   That is 1A draw for 
110hr would completely drain a 110Ah lead-acid battery, but at 150A the battery 
would drain out in 1/4 hr (or even much less, not 3/4 hr as 110Ah capacity 
suggests). The claim is that the Li-Fe batteries have much less internal 
resistance which why they use the “EqAh” (or AH PBEq).

It is sort of like using Watts to measure lightbulb intensity. 

Below is an interesting exercise demonstrating why we likely have not 
heard much about Li-Fe battery for marine deep cycle use.

Very interesting battery banter.   For me the best flooded U1 is probably the 
way to go, I bet I can fit that with the existing batteries under the qb.  .  
450 cca, and the same charging profile as my grp 31 flooded house bank.  (The 
xantrex charger makes you select one one profile for all batteries)Less 
expensive, I know it will work, and it's deep cycle capabilities are not really 
relevant for this application.  Thanks all.

Re: Stus-List small start battery for yanmar 3hmf

[Dreuge via CnC-List]

My first impression is to be skeptical of using a motorcycle battery to start a 
much higher compression diesel engine.  

So these batteries claim 270 CCA of power and 18Ah of energy.  So is this good 
enough?   I think it is reasonable to assume that a starter will consume less 
than 270A of current during a start.  At least I know that my Yanmar 3QM30 uses 
less than 300A since I have 300A MRBF fuse at the battery(And I am sure that 
250A fuse would work fine too).  To be generous, let’s assume that one cranks 
the starter for 10 seconds.  This amounts to 270A * 10s / 3600 h/s which is 
0.75Ah.  Good for many starts without charging.  This also implies that an 18Ah 
battery should turn the starter for about 18Ah*3600s/h/270A = 240 seconds or 
about 4 minutes (of course nobody should crank this long).

Another concern are battery fires, but as I just read  Lithium-Iron batteries 
are not  Lithium-Ion batteries.   Li-Fe are supposed to be safer.   Wikipedia 
has a nice article on Lithium-Iron batteries:   
https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery.   

But still, just google “Lithium-Iron Powersports battery fire” and one of the 
first links is a YouTube video titled “Shorai battery fire”.Amazon has many 
good review, but one bad one titled “Do NOT order this battery”  describes the 
battery catching fire and shows an image of a burnt up battery.

Another Amazon review points out the misleading Ah ratings.   Here is a quote 
from the review,” The stated Ah rating of 18Ah is only an "amp-hour pb 
equivalent" used to compare it to lead-acid batteries in terms of starting 
power. The actual rating is only 6Ah - which is on a little sticker on the 
bottom of the battery when it arrived, but stated nowhere online that I could 
find.”   

The manufacture claim that the Li-Fe battery should be charged with voltages 
between 13.1V and 15V with a maximum charging current of 10Amps.   This seems 
like a nice match for a motorcycle but not for for a multi-bank battery system 
unless one rigs up a trickle charge system for the Li-Fe (maybe a Xantrex’s 
echo charge). 

So the bottomline is that it has 6Ah of energy rather than 18Ah (80 seconds of 
max start time), and while they claim to charge fast, manufacture specify that 
max charge voltage be no great than 15V and max charging current be no more 
than 10A.   The later, may be an issue with typical +80Amp marine alternators.

With only 6Ah for the price , I still remain skeptical, but see some future 
promise.  It is rather bogus that manufactures are using “EqAh” ratings to fool 
people into thinking that the stored energy is greater than actual.

[Josh Muckley via CnC-List]

Thanks Joe,

I was gonna say most lawn mower/tractor batteries (U-1) have about 30 Ahs
and are rated anywhere from 200 to as much as 450 CCA.  Until now I hadn't
heard of anyone using one as a starting battery on a boat but your example
is proof that it works.  Knowing that my "6Ah"  battery got my 3HM35F
going, I figure there has to be a lead acid option out there that would be
a best balance between power and size.  U-1, motorcycle, SLA, etc

Paul,

When this discussion came up in the past someone quoted the yanmar owners
manual as stating that the minimum CCA of a starting battery should be 200.

I really appreciate the added research into the eqAh rating.   That is some
misleading bullshit.

As for charging at the rated amperage of 10amps the IIRC the echo-charge
will charge at up to 15 amps.  Maybe close enough to not cause any problems.

It probably wouldn't be ABYC compliant but the li-po jump starters come
with a cigarette lighter re-charge cable.  It would be possible to hardwire
power to the charger from the house batteries AND hard wire the alligator
clamps to the starter.  This would ensure that only the li-po started the
engine and that it only got charged by the appropriate charger.

Re: Stus-List small start battery for yanmar 3hmf

I have purchased a "spare"  3HM35F and it is sitting in my garage.  I have
some old AGM batteries which used to be rated for 75Ahs.  They currently
only test at about 6Ahs.  Since they were sitting around waiting for

to crank the engine for a total of about 45 seconds.  I think that one of
those lithium batteries at 18Ahs would probably get you a minimum of about
3 minutes of crank time which should be more than enough.

I'll tell you what, I'll do the testing if someone else provides the

I have purchased a "spare"  3HM35F and it is sitting in my garage.  I have some 
old AGM batteries which used to be rated for 75Ahs.  They currently only test 
at about 6Ahs.  Since they were sitting around waiting for disposal I grabbed 
one and hooked it up.  It started the engine without a problem.  Keeping in 
mind that it isn't a "good" battery, it was only able to crank the engine for a 
total of about 45 seconds.  I think that one of those lithium batteries at 
18Ahs would probably get you a minimum of about 3 minutes of crank time which 
should be more than enough.

I'll tell you what, I'll do the testing if someone else provides the battery.

I knew I'd seen some cool options.  Those looked pretty awesome!  Small
enough to fit anywhere and powerful enough to start.

As discussed on this list before, an ACR or Xantrex Echo-charge is what
you should use to keep the start and house banks separate but allow the
alternator to charge both.  A combine switch allows for emergency starting
with the house batteries.  A very small lead acid battery is enough to turn
the engine.  If you don't have enough room for a U-1 tractor battery then
you might find a motorcycle battery that will fit your needs.  Even two 6v
