Interstate SRM 27 battery is not cutting it

Hi guys,

My setup (see below) gives me from daybreak to around 2 pm or so. This
is not cutting it for me. It is a new battery as of January, the water
is at proper levels, and I always charge it back up right away.

There is enough room to mount another battery or is there a single
battery solution (make and model) that I should know about?
I looked through my MotorGuide manual and couldn't find how current it
draws. I will keep looking.

I considered a Combiner 100 but my boat does very short runs on these
small SoCal lakes and I am not sure if that would be sufficient enough
to charge the SRM 27. I use the TM mostly down here on these "ponds".

Any advice is welcomed.
I am thinking of either adding a battery (but that would extend my
overnight charge time should I want to fish the next day) or, replacing
the Interstate with a higher quality/capacity battery if there is one
out there. Is there one that will last all day?

Thanks again.

My first reaction was to diss your Interstate battery. I've had bad luck
with that brand. However, realistically a single battery probably won't
have the capacity you want regardless of the brand. Two batteries in
parrallel would work better. If you want to try and stay with one you could
go with a high quality group 30/31 battery but not knowing what you are
hoping to achieve I would say that would probably only give you another
couple hours of fishing time. Yout thought that you should have two
batteries is probably the best option.

Another note.... 24V TMs tend to be more efficient at the same net output
than 12V TM. Variable speed TMs also seem to work better than multi speed
TMs. So... that may be something to keep in mind for the future.

My few questions are..... what size (thrust)TM are you using, and what size
wiring is running from the battery to the TM? I went through the same
problems when I first got my boat, about 6 hours use if I was lucky, and
less if I used #5 speed on the footpad. My TM is a 54# and the #10 wiring
wasn't working well. Run your Tm on high for about 10 minutes and feel the
wiring, if it's warm to the touch you need to upgrade the wiring. I went to
#6 soft wiring for Pos and Neg side and I can now go days on one charge.

It is a 46lb and the wire is beefy looking.

Bob,

I am probably going to get another Interstate SRM 27 and hook it up in
parallel with the one I have.
Then I will devote the charger to the 2 trollers. The cranking battery
gets charged decently from the outboard.

Thanks!

Ted

I would also guess the 4 A charger is not cutting it. You need some
quality amps for a deep cycle battery, around 10A I'd say..

Also if you hook up that 4A charger to batterys in parallel it will give
only 2A per battery..

I would use the 2 bank charger exclusively for the 2 TM batteries.
That would provide 4 amps per battery.

My Evinrude E-tec 50 charges the cranking battery pretty well.

Ideally I'd like to have a more powerful 3 bank charger and higher
quality batteries such as Ac Delco or Trojans, but I will need to save
up for that.

I am hearing now that the AC Delco Voyager, the largest one (30), would
pull my boat around all day no problem, by itself.

I will do some more research.

Even #10 wiring can look beefy.
