squidboy Posted April 29, 2016 Share Posted April 29, 2016 Looking at upgrading to a 24 volt minn Kota. Going to run two 12 volt batteries. Just wondering whether I will need a 24 volt battery charger or will a 12 volt do. Both are the same type, age, condition and capacity of battery. Also wondering whether it would be OK to charge them and leave them on trickle charge together? Thanks for any help in advance Link to comment Share on other sites More sharing options...
onearmedfisho Posted April 29, 2016 Share Posted April 29, 2016 (edited) I can sell you a 24V Minn kota or Motor Guide if your interested? I opted for the motor guide and I run an on board charger which just plugs into 240v when i get home. Pm me if you want some red hot pricing...

sydney south Posted April 29, 2016 Share Posted April 29, 2016 I would say that you and connect your 12volt batteries in series to run the Minn Kota. For charging you could then connect the charger on parallel to the batteries. Link to comment Share on other sites More sharing options...
Greyfox Posted April 29, 2016 Share Posted April 29, 2016 Just remember if you have all your electrics and electronics comming off the one 12volt battery you will have more drain and therefore longer charging time than the other 12 volt battery if it is for only running the Minn kota. What is the charging capacity of the outboard/ inboard motor. Link to comment Share on other sites More sharing options...
squidboy Posted April 29, 2016 Author Share Posted April 29, 2016 I'm running a 15amp ctek charger Link to comment Share on other sites More sharing options...
Choicebro Posted April 29, 2016 Share Posted April 29, 2016 Hey mate, My .02c comment would be that your Ctek charger @ 15 amps would struggle to charge a 24v system. They are a good charger but charging 24v will require a charger with a higher amperage output. You could isolate the batteries by disconnecting them and charge them separately, but this would obviously take twice as long as using a charger designed for 24v. If I may ask, what is your reason for upgrading to a 24v minn kota? I run a 12V minn kota with a deep cycle gel battery and have never had any issues with a flat battery or lack of power. I usually only recharge after 3 or 4 trips. Recently I took the boat out after a 9 month lay off and still had 3/4 charge in the battery with no issues on the water Interested in your response.

Guest Posted April 29, 2016 Share Posted April 29, 2016 I have an 80lb minn Kota and have had it for years and charge it with s C TEK and never missed a beat and the 80lber goes into 20 knots ... Try that with a 55 Link to comment Share on other sites More sharing options...
squidboy Posted April 29, 2016 Author Share Posted April 29, 2016 Stewy, so are you charging your 24volt set up with a 12 volt charger or a 24 volt charger? Link to comment Share on other sites More sharing options...
