Thread: 12 volt batteries

What you have described is wired in parallel yes that will give you more running time......it will give you 12 volts that way

Tks sorry ment parallel good i can fish longer

Almost twice as long. Bring plenty of Beer

If you hook an onboard charger to a set of batteries hooked up in parallel will it charge both of them evenly?

Yes...it will take twice as long though if you only hook up one bank......If you have enough banks you can hook a bank to each battery, that's how I have mine. If you just hook up one bank just hook it to one battery and it will charge them both.

Run my Terrova like that. Have charger hooked to one battery. Have never had a problem with batteries not charging overnight. Also have never run them down except once pulling cranks in the wind.

Here's a question hopefully someone can help me with. I have a 24 Volt Motor Guide 60lb that I have been running off 1 battery all last year and trolled for 6 hours yesterday. I understand two 12volts to make a 24 volt, but why is my Trolling motor even working off a 12volt and I have never had the battery die on me. I have it on an old 1990 Quantum bass / ski boat and never had any problems moving it around. Should I change it to 2 btrys if its working fine like it is? Or should I just get another btry and set up parallel for time?
