I have a Sailfish 176. One battery is mounted in the bilge tray slightly ahead and above the bilge pump along with the battery switch (Perko 8501). The other battery is mounted in the starboard transom locker area and is almost as high as the top of the engine (Suzuki DT100). The port side transom has the bait well.<br /><br />I can fit both batteries side by side in the bilge tray. Is there an advantage to have the batteries geographically dispursed and/or one higher than than the other?<br /><br />Is it advisable to mount them side by side in the bilge - or keep them where they are?
