Onboard charger broken, two options...what would you do?

[Junger]

So my DualPro Sportsman4 has 1 bad bank, and is out of warranty. I switched leads with another battery and tested it that way. I would have to ship it to DualPro, and a repair would be about $70. I had planned to upgrade the profile to charge LiFePO4 batteries too, that's another $180. I'd have to pay for shipping, so maybe $20-40 each way. So I'm looking at $330 out of pocket to refurb it.

 

But when I was troubleshooting the charger, I wanted to make sure the battery wasn't dead, so I hooked up a NoCo Genius 1x to each battery. Even though the DualPro lit up the 6th LED on the good banks, the NoCo had them at 75% and they kept charging until 100%.

 

So, either the DualPro's charging profile sucks, or NoCo is overcharging. I'm thinking the former.

 

So my options:

 

1) Send the DualPro to get refurbed and update the profile to charge LiFePO4's for $330 and no warranty.

2) Just rip out the DualPro and get a new NoCo GenPro 10x4 for $460 (after tax) with a 3 year warranty.

Go with the NoCo - I won't have any other charger on my boat.

I currently have Dual Pro Recreation charger that is only compatible for lead acid or AGM.

 

When the time comes to make an upgrade, I’ll be going with a Noco charger.

Had a ProMariner on my old boat for three years...and went with ProMariner on the new boat. They stay plugged in 24/7/365. No issues so far.

I switched to a Noco Genius 3 charger when I got my Impulse Lithium batteries and they do a great job fully charging each battery.  I highly recommend them.

 

If anyone is using Ionic batteries, some charger info from a trusted retailer who sells a lot of batteries.  I'm not criticizing Ionic, they're great batteries, just a little quirky with some chargers:

 

 

Lithium Charger settings Minnkota and NOCO
just so there is no confusion and with past post and info that gets shared about chargers and lithium's and Im mainly speaking on Behalf of IONIC

Yes you can use a Minnkota Precision Charger as in MK440PC or MK460PC, you will use the AGM setting, it will charge fine but your indicator lights 25% 50% 75% will not be accurate just ignore them, when the batteries are charged it will turn off and show charged at some point,
the Newer Precisions its fine to just use the lithium setting

NO you can NOT use a MinnKota digital as in 330D or 440D or as many call the 3300 and 4400 the D must look like a 0 down in the bilge

NOCO Chargers
if you have a NOCO Gen Pro do not use the lithium setting on IONICs, use the AGM setting instead , you may have been using the lithium setting and it may be working fine but there seems to be some inconsistencies from one charger to another, the AGM setting will push the peak a little harder to get the voltage we like to see
if you are using the lithium setting and its been working fine and your batteries still rest at 13.4 to 13.6 at 99% you are fine
