You asked: How big of a battery do I need for my kayak?

You’ll likely require a 12V battery if you’re using a canoe or kayak, as they usually weigh less than 100 pounds on average without all the items you load inside. But you could still consider extra voltage if you plan on powering multiple items alongside your motor.

What kind of battery do I need for a kayak?

How long will 100Ah battery last trolling motor?

How long will a 100Ah battery run a trolling motor? A 100Ah lead acid deep-cycle battery will run a 30lbs thrust trolling motor on Speed 4 for 4 hours.

What size battery do I need for a 55 lb thrust trolling motor?

How long will a 100Ah lithium battery last on trolling motor?

(100 amp hour rating / 4 amps = 25 hours). Similarly, if the motor was running at top speed and pulling 40 amps, the battery would last for 2.5 hours (100 amp hour rating / 40 amps = 2.5 hours). For more information on understanding battery run times, please see our guide on understanding trolling motor run time.

How many solar panels does it take to charge a 100Ah battery?

A fully discharged 12V 100Ah auto battery will need 3 solar panels each rated at 100 watts to fully recharge in one day, assuming average 4 peak-sun-hours. A 100Ah lead-acid deep-cycle battery discharged to 50% of it’s capacity will need 2 solar panels each rated at 100 watts to fully recharge in one day.

How many amps does a 112 lb thrust trolling motor use?

A 112# thrust 36 volt would use approximately 38 amps at full speed, 20 at half speed.

How long will a 12V battery run a trolling motor?

Almost 5 hours doesn’t seem too bad, but that is really a max runtime in ideal conditions. Reality is likely to be less. If the battery is old, damaged or not fully charged then you will not get the rated amp hours from it, reducing your runtime.

Can 100Ah battery run a fridge?

A 100Ah lead-acid deep-cycle battery will run a fridge using 630kWh/year for 13.3 hours. 80% discharge is assumed, but at the recommended DoD of 50% the same 100Ah battery will run the fridge for 8.3 hours. A lithium iron phosphate 100Ah battery will run the fridge for 15.8 hours at 95% discharge.

How long will a 100Ah battery run an appliance that requires 1200w?

A 100Ah deep-cycle battery will power a 600W DC device for about 1 hour. (A 100Ah battery equals 1200 watt-hours but only 50% should be used.) At 600W AC appliance will only run for about 0.86 hours because an inverter is needed to convert voltage from DC to AC and these devices have losses.

How long will a 100Ah battery run a 1000W inverter?

A 12 volt 100Ah deep-cycle battery with regular depth of discharge 50% would run a fully-loaded 1000 watt inverter for 34 minutes. This calculation takes into account average pure sine wave inverter efficiency of 95%.
