Thread: A question about battery chargers

As long as its just charging one battery at a time, that will work.

Yes, it will be charging just one at a time.

you could add a switch and charge the 2 batteries in parrallel. it would take longer to charge them but it would work.

BPS has a dual 5/5 amp on board battery charger on sale for $99.94. Sale is thru 02/26. (normally $125)

I run 2 batteries up front in series for the T/M and flasher. T/M is 12V. I have a 4 amp dual charger and it does just fine (around home) keeping both batteries charged. If I'm on an extended trip, more than 3 days and doing alot of trolling, I bring my 10amp and alternate between the 2 batteries using it at night.

Since your new T/M has a maximizer it probably draws alot less amps than my old 5 speed T/M. It will probably do just fine. I hoping that my batteries hold up alot better with my new T/M, since it's digital and will draw less amps.

The only time I need to charge my outboard battery is in winter. In weather like this, it sits too long between running. Not to mention it probably needs to be replaced:rolleyes:

Yeah, I've been looking into a two bank. I am trying to hold off and get a Minnkota 10/10 amp. I'm planning on buying a Humminbird Side Image soon, which will put off any more significant purchases for a while. I have a portable 10 amp charger that works fine, but it's a pain to get to my electronics battery. It's up under the front deck. The access door opens right above the TM battery, which makes it easy to use the portable. But since it's not so easy to get to the other battery, I find myself letting it go uncharged too long. If it's just a matter of plugging in and flipping a switch, that may not happen. I'm sure the HB SI takes more juice to run it, so I figure keeping that battery charged will be important. And yes, I have the Minnkota PDV2 TM with the digitsl maximizer. It really cuts back on battery draw. And I hadn't charged my cranking battery in a couple months till this ridiculous cold came along. Now they are all in the house out of the weather and fully charged.
