I am looking to direct mount a battery maintainer to a Cam Am Defender and use a Noco receptacle to allow for shore power to be hooked up via an extension cord. Basically the large winch on the side by side sucks the juice from the battery, and since use in the winter isn’t extended riding, I’m not confident the magneto would have the run time to keep things topped off. So I’d like to be able to occasionally just plug the machine in after plowing.
The battery in the unit is a Yuasa Y1X30L, a 30Ah AGM which suggests a 3A charge.
Here’s where things get difficult.
Noco makes a Genius 2D that is a direct mount charger made for lead acid including AGM batteries. The issue is since you can not set a specific charge mode the charger operates at a consistent 14.5v which by my understanding would only charge a 12v AGM to about 80% and never top off the battery.
They make a Genius 2 (no D in the model number) That does have specific charge modes and the AGM setting would charge between 12.6 and 12.8v which as I understand would top off an AGM batter. The problem is, Noco tech support was adamant it couldn’t be direct mounted in the cab of a vehicle because it wasn’t water proof and couldn’t take the heat of the engine compartment. Again this would be mounted in a climate controlled dry fully enclosed side by side cab.
On several forums Defender owners have pictures of the Noco GEN 5X1 direct mount charger. This is fully waterproof, and used frequently on boats. This charger share the smart maintainer features of the genius 2 however it is a 5A charger.
Yuasa gave me 2 answers. 1) we recommend charging the Y1X30L at no more than 3A. And… 2) Given the size of the battery you should be ok to charge it it’s a 5A smart charger but “just keep an eye on it.”
This is decidedly confusing. I recognize low and slow as being the best for the battery, however, I really would love to just plug this thing in after an afternoon of heavy snow plowing and leave it over night. I also realize just clamping on a 1 or 2A smart charger to the battery posts would suffice however I’m set on mounting this receptacle to the side of the machine.
SO the main question is, do you think I can occasionally charge this battery using a 5A Noco GEN 5X1 charger?
Thank in advance for your thoughts
