Mixing batteries Start v House

[DRock3d]

I have a TPPL AGM group 31 house battery that has been great, I can never drain it on the water. It's heavy as can be and makes my boat list pretty heavily to that side. I've been running a group 24 lead acid as the start battery and it's finally time to replace it

Is it an issue to run different sizes for start/house?

Any recommendations on a lightweight start battery?

FWIW that is how my setup has been since 2008, never had an issue. I LOVE my BlueTop, I can't kill it... that battery has to be at least 8 years old if not more and I have run it dead several times.

Any recommendations on a lightweight start battery?

I'll let the others chime in... I myself would steer clear of LiPos, but that's just me. I have always preferred lead acid for the crank battery, but I will look at alternatives when I need to replace it.



Yea, I know... I'm still cleaning the boat...
