Sector E1 Battery change out

[Gorj]

I am going to replace the batteries in my E1. I am not interested in the high cost Lithium or the expensive 6 volt dry batteries.  I am considering four 12 volt deep charge marine batteries. I have a source for 810 amp units for about $100 each.  I have no worries about reprograming the charger because it went out a few years ago and I replaced it with generic golf cart charger. When I decide to do this, I'll keep you posted on the results.

I would suggest you look more closely at the continuous discharge rate of those batteries.  810 is almost certainly just the cold cranking amps.  I suspect your performance in a UTV application is going to be seriously degraded - like at best a continuous rate of under 100A and potentially even less.  Plus, even a deep cycle battery can only go down to 20% and there will be a voltage drop.

Also, the plates used in deep cycle batteries are often not made of the same material and thickness as those in batteries rated as traction batteries, so in the UTV application the marine batteries are going to fail sooner than even the Discover batteries.

I was able to do a load test on the Discover batteries and seven of the eight batteries passed. It was the defective battery that was the problem. I am replacing it soon and expect things will be back to normal.

I replaced the defective battery and everything is back to normal. Installed digital volt meter shows 51.9 volts when fully charged. Am again able to climb the steep hills on my property. I did not replace the expensive Discovery battery. I used a deep cycle marine 6 volt battery.
