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.

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 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 am into five years of ownership of my electric side by side and I am noticing some deterioration of power. Although I measured the voltage at over 49 volts, I believe the batteries are beginning to fail. I charge them about twice a week. Last year the charger went out and I replaced it with a 48 volt golf cart charger. What has been your experience with the batteries?

I have not installed it yet. But it would need to be installed where it can be accessed by hand with two brake lines run to a brake line going to the UTV's brake line. It would be like cutting the brake line and installing the valve. How it works is you put pressure on the brake fluid with the brake pedal, activate the valve and it holds the pressure, thus holding the brakes, until you depress the brake pedal again that releases the valve and thus releases the brakes when you let up on the pedal.

I AGREE. The E1 is, for me, a very useful tool. I do not like small gas engines, so the electric engine is great. Around my 20 ac. I do not need anything more.

No, I don't have any problem with the brake light switch.

The parking brake is a piece of CRAP! I recently purchased a brake line switch/valve that will lock up the brakes when activated. Race cars use them. I am going to install it in the Spring when it is warmer. Right now I do not park it on any inclines without putting a block under a wheel!

Yep. Replaced the battery charger with a 48 volt charger from a golf cart. Found one on eBay. Works like a charm. Did not mount it where the old charger was mounted because it was difficult to get to so I mounted it in the area under the hood. I also cut a hole in the frounk for better air flow.

Yes, I checked tht fuse. There is no power coming from the charger. There is power going to the charger, but nothing coming out! I am going to pull the charger and check it out.

Yesterday my Hisun Sector E1 stopped charging when plugged in. Anyone one have an idea of where to look for a problem?

The 12 battery was replaced last year. It is in good shape. Actually I checked the voltage going to the solenoid and it is 24 volts. So it must get its power from half of the drive batteries. I made a small 3/8" hole in the plastic area of the solenoid and sprayed contact cleaner in the contact area and then blew it out and cover the hole with a plug. So far everything is working as it should.

The batteries will last longer if you keep a charge on them about once a week. I would suggest you use a timer to charge every ten days or so when parked. The batteries are expensive and you do not want to have to replace them. I am on the original batteries now for four years and I charge once a week all year around..

Thanks for the suggestions. I had read the manual for the diagnostics on the code. I have checked and cleaned all the visible electrical connections. Although I have seen no corrosion, I applied an anti corrosion spray and cleaner. I have also checked all electrical connection for tightness. Right now it is working fine. I will wait and see what happens in the future. I am in the fourth year of having this E1 and except for the parking brake never working well, even though it has been in the shop for a repair, it has been a very reliable vehicle. I the idea of the EV, for I have owned an EV car and two hybrids, but I am concerned about how sensitive all the electronics are and the fact that there are few techs that can repair them. Fortunately I am both a retired auto tech and a retired IT so I do have a few insights into their workings.
