Battery charge/ trickle chargers

My boat has a system of 24 volt trolling motor and 12 volt cranking. Typical.

What do you guys use?

I looked into 24 volt trickle and found some unexpectedly high prices.
So I had the grand idea of putting a blade switch in the battery jumper and bring post leads out and connect them in parallel. Use one trickle on the ignition and one on the trolling set.

Thanks

Three bank on-board charger. Just hook an extension chord up and forget about it.

What tiger said. Direct hook a 12v 3 bank, install an outlet.
I use minnkota brand chargers but only had it 1 yr.

I used this plug

Buy your own screws, the ones mine came with started to rust.

2 Bank charger I got. You would need the 3 or 4 bank.

Onboard charger. $100 give or take $20. Takes about 30 minutes to install depending where you put it.

I like the guest chargers myself. They’ve had good reviews. I’ve had mine over a year and it’s been soaked multiple times(under front deck). I’ve since relocated the batteries and charger under the console.

I used the same plug that frio put a link for.
here’s the charger. I just picked up a second one on amazon lightning deals for $60. Now I need to get another boat so I can use it.

edit to add: the 3 bank chargers are significantly more expensive. Infact, almost twice the price. I never need to charge my main batteries since I get out a lot. But if I do, I just use a regular charger or run the boat in the yard. Or you could buy two onboard chargers.

Really like my Noco Genius 3-Bank (30 amp) charger. It’s “smart” so it accesses and maintains the batteries even if left on for long periods. Looks more pricey than I remember paying. Watch for deals. http://www.amazon.com/NOCO-GEN3-Waterproof-Battery-Charger/dp/B003JSO1X2/ref=sr_1_1?ie=UTF8&qid=1411996061&sr=8-1&keywords=noco+genius+3+bank
