How to Install Dakota Lithium Batteries in a Bass Boat

How to Install Dakota Lithium Batteries in a Bass Boat


Putting new Dakota Lithium Batteries inside your bass boat is as easy as just replacing the old batteries and putting in your new lithium batteries inside. The only trick is making sure that you have a lithium battery charger. Otherwise, installing your batteries is pretty seamless and shouldn’t take any longer than 10 or 15 minutes. Also, it’s super convenient Dakota Lithium sends you all the hardware you will need to install when you buy a battery. You won’t need anything other than a few wrenches to tighten the bolts. In this example there are three (3) batteries to install plus an onboard charger.

Step 1) Installing the Dakota Lithium Marine 4 Bank, 40-Amp (10-AMP PER BANK) 12V Onboard Lithium Battery Charger.


This step can be totally skipped if you already have a lithium battery charger on board of your boat. But in my case we will need to install a battery charger. Depending on where you want to install it you will only need a couple of things. A drill and four (4) 13/32 head bolts and nuts to mount it. You can use screws depending where you are putting it, but would recommend bolting. The onboard charger has mounting slots on the side of it in different locations that make it easy to install.


Once installed where you would like it close to the batteries, you just need to plug in the ring connectors to the wires already installed in the charger. The separate ring connector is a super awesome feature Dakota Lithium provides, so if something happens to the ring connector you can just easily buy another one and plug it right back in. We’ll hold off on plugging the ring connectors up to the batteries until we get those installed.


Step 2) Installing two (2) Dakota Lithium 12V 100AH Deep Cycle Marine Trolling Motor Batteries


You could easily say that pulling your old lead or AGM trolling motor batteries from your boat would be the hardest part of step two. But no worries as the new lithium batteries are very easy to put back in as the Dakota Lithium 12V 100AH Deep Cycle Trolling Motor Battery only weighs in at 31.9 pounds compared to most lead or AGM batteries weighing in at over 70 pounds.

Once inside the boat it’s just simply wiring them back the correct way and adding your charging wires to the batteries.


Step 3) Installing the Dakota Lithium 12V 135AH Dual Purpose 1000CCA Starter Battery


Rinse and repeat from step two. The 12V 135AH battery weighs-in at 27.2 pounds. Only thing you might want to consider with the new cranking battery is the width. It is smaller than most AGM and lead batteries, so you might consider another battery tray just for it which you can find here.

It’s important to note that if are starting up your boat a lot through the day and using power from this battery to power fish finders and accessories and others you might need to consider a Victron Orion-TR Smart 12/12-18A Isolated DC-DC Charger to charge your battery while the motor is running. This will keep your lithium battery charged and flowing all day long.


Step 4) Enjoy! It’s awesome to have boat batteries that you can install and rely on!
