Battery upgrade

7330 Views 6 Replies 5 Participants Last post by  fswan
Has anyone else had any issues with drawing your battery down? I have a 900xp esp with Polaris heater, stereo with 300 watt amp, extra lights, and a Meyer 72" electric over hydraulic plow. I know it is a lot, I have killed it twice plowing now. Just wondering if anyone has any ideas on a better battery setup, or upgraded charging system?

All these machines charging system generally can't keep up once you add the extra draw like the things you have which is typical. Get in the habit of connecting a good trickle or smart charger when you are not riding to have your battery fully charged each time you head out. Many upgrade to a larger battery or various dual battery setups. That will help if but you can't keep up you charging needs now you still won't with dual batteries, it will just take longer to draw them down. If you use an isolator with duals you can keep your starting battery hot all the time and just use the aux battery for the add on acc. Regardless for optimum performance connecting a charger when done riding is a must IMO. There are some upgraded charging systems but the ones I have seen are expensive and require a belt and hole in you belt/clutch cover. They are not popular for those reasons.

I do plug it in after every time I use it, just thought there may be a bigger battery to switch to as well.

Bigger battery will just delay the problem. The proper fix would be to get a better charging system....which from what I've been looking through, doesn't really exist. Be nice if someone would come out with a high output stator and flywheel.
That is no different than saying a larger gas tank won't stop you from running out of gas. Which is true, but it will let you go a lot further between fill ups. Same thing with adding more battery for aux loads. It will still run down but it will keep things running long enough for your needs and keep you out of a bind until you can recharge.

I would think a larger battery with an onboard charger to plug in when not in use would probably work. Unless your plowing for long periods of time on short driveways. On shorter driveways you would be using the winch more often to raise and lower the plow. The winch is what kills the battery.
If you are draining your battery frequently, you may want to switch over to a deep cycle battery. Starting batteries (OEM) don't hold up well to repeated deep drains.
