| does a fully charged group 29 battery produce more power than a fully charged group 27 battery? Will a group 29 pull the boat at a faster speed, or just have a longer run time. This is assuming both being new and fully charged, and running at the same setting.

I am not certain, but I think it would simply provide longer run times. |

Struth. Power depends on voltage, and they're both nominally 12V. You'll just get a longer run-time. |

| Run time only. |

Location: Contrarian Island | you would have to look at the specs on both... there can be quite a bit of variance in the RC time ... if the 29 has more RC capacity then yes, it would just provide longer run times.. it will not pull it any faster on the same setting as the 27. |

| 2 points on batteries:
1) Example a size 31, Marine Deep Cycle Battery is used to power a trolling motor that draws 55 amps at max trust. The motor can then run for (108 ah / 55 Amps = time) ? 1.96 Hours. Before the battery drops below ~ 10.5 Vdc, which is generally considered the minimum voltage for trolling motor, lights, fish-finder, etc. For starting the voltage needs to be > 11,5 Vdc, but if recharged by gas motor the life cycle varies.
2) Marine Cranking AMPS (MCA)- equals the number of amps a battery can deliver at 32 degrees Fahrenheit for 30 seconds and maintain at least a voltage of 1.2 volts per cell (7.2 volts for a 12 Volt battery). This differs from cold cranking amps which are measured at 0 degrees Fahrenheit. This is the most useful spec when determine which battery to select.
