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.

I am having an erratic issue. Sometimes the solenoid/relay does not activate when switching on the power. Thus the electric motor does not work. You can hear the solenoid activate because it is right under the seat in the middle. The solenoid/relay connects the batteries to the electric motor circuit. When it fails at making the connection I get a 54C3 code on the display.

The parking brake on this unit is a JOKE. It is a very crude disk brake on the drive shaft. I can imagine that it could NOT release if left engaged for a long period of time. But since it rarely works well I do not think that would be an issue, unless it had recently been adjusted to work. I find that after adjustment it works well for only a few weeks. It is a VERY POOR design. I carry a block of wood in mine to put under a wheel to hold it on a slope! I have discussed with my dealer about this issue, but have received no satisfaction . I have considered installing a brake line cut-off valve. It works by holding the pressure on your brake fluid (like having your your foot on the brake all the time), then when you push on the brake pedal it releases.

The parking brake on the E1 is a very poor design. In the year I have owned it I have had to adjust it four or five times. I have to adjust about every month to six weeks. I think it was designed by an idiot. Which is possible because there are a bunch out there! I may have to put a hydraulic lock on the brake system. That will lock all four wheels.

It looks like one would need to use one of their chargers to have the ability to use their app.

I have not found anything but a pdf file that list the specs. Hisun does not seem to customer friendly. I have managed to get my local dealer to photo copy some mechanical and wiring diagrams. If you don't have a good local dealer you are on your own with Hisun. They are more of an assembler than a manufacturer. They are shipped in from south east Asia in pieces to North Texas, assembled and then shipped to dealers.

Might try checking to see if your wheels are tight. Lit it up in the air at each wheel and see if there is any play in the wheel. If so take out the cotter pin and tighten the nut. Simple.

I have never liked the cord in the glove box to charge the E1. It takes up to much room and in the winter the cord is very stiff. So I decided to install a charge port like the EV's have. I purchased a weatherproof socket to install in the side of the E1. Wired the charge cable to the socket and installed it. So much easier now to plug the charge cord into the socket, and I have more room in the glove box. On another note: Since I have owned the E1 I have noticed a rattle in the right front area but I never could locate it until last week when I had the E1 up in the air on a lift. When I grabbed the right front wheel it a play in it. So I removed the wheel and torqued the nut on the drive shaft and the play is gone. I am thinking when it was assembled the nut was just hand tightened and the cotter pin installed. I also found that the left front nut was not tight either. Backs were OK.

I have had my E1 since late last summer and I have always noticed that the parking brake was weak or non existent. About a month or so after I purchased it I mentioned to the dealer that the parking brake did not function well. What I was expecting from the dealer, ' well bring it in and we will correct the issue.' What I got was the typical dealer response, "it may just need to be adjusted." No shit! Well I finally decided to adjust it. A very simple process need only two 10mm wrenches. Open the bed, remove the pin holding the bed to the strut and move the bad out of the way. Right in front of the electric motor is a brake disk. That is the parking brake. It has a small set of brake pads that are actuated by a lever attached to parking brake cable. There are two 10 mm nuts on the shaft to moves the pads. Release the inner nut and hold it in place while screwing in the outer nut - that is really a bolt. After screwing it in about one turn, tighten the other nut. Check the parking brake. If it is holding when activated, then you are good, but if not, then you may have to turn the bolt another turn. Do not turn to far or you will lock it up.

Mine and some others that bought one from the same dealer came with a 2 inch adapter that fits OVER the Hisun receiver. I think Hisun left that off your unit. Dealer should provide you that adapter.

I hope you get it sorted out. We call our E1 the Mule, for our other side by side was a Kawasaki Mule! Our two wheeler with a handle that curves out, we call Dolly Parton! A funny: You know what Moses used to part the Red Sea? ..... A sea saw!

Thank goodness we do not have really cold temps here. If one battery is defective it affect your power output. In an emergency there is something you can try. Remove the bad battery. With the power off. connect the two battery cables from the removed battery. If the other batteries are good and charged, you should have enough power to move the vehicle. I have never tried this but technically I think it would work.

In the last year he has had three batteries replaced.

The local Hisun dealer has sold only four E1's in this area. Like me, they use them on their farm/ranch. Chickens and cattle are big in this area of Arkansas. Part of the reason more are not sold here is Hisun is not pushing them in order to sell their gas models. Those who want them have to wait six to 10 weeks to get one. The Hisun distributor in the USA is in north Texas and unlike most Texans they are not to customer friendly! I also have found the inability to purchase certain vehicles in the automotive world. Eighteen months ago I wanted to purchase a plug-in hybrid from Hyundai. I discovered they only sell on the east and west coast of the US. Dealers can not even get them! So I ended up buying a Hyundai Ioniq hybrid. I have really enjoyed it, especially the mid 50's mpg. But if I could have bought the plug-in version I could have gone about 30+ miles on electricity, and most of my round trips from home are less than 30 miles.

There are a few SxS's that use newer technology, ie. lithium batteries, but they are really pricey. The gel batteries in the E1, even though very heavy, work well and are not as temperamental as the lithium. The heavy batteries also give the E1 the ability to pull a heavy load without loosing traction. For example, I got my Dixie Chopper lawn mower stuck in deep mud a while back. I was able to pull it out with the E1.

Some of these battery issues may be due to the BMS (battery maintenance system). I own a hybrid vehicle and there is always talk on the forums about issues with the BMS. It seems like with electric vehicles the BMS is the brains of the electrical system. I wonder if the dealers that are servicing these electric units really understand what they are working on!

Have a friend here with an E1 and he has had battery problems too. In his case I think the batteries set to long either at dealer or distributor without being charged. These type of batteries need to have the charge kept up on them or they go bad. Hisun has replace several of them under warranty. My E1 was fresh out of the distributor and did not sit around at all. I have had no issues. I charge it about every two weeks, but the charge level has never gone below one notch of the gauge. I have never driven mine far. I use it only on my 18 acre place. I have a small mountain at the edge of my property and it has no issue navigating it. It is always parked under cover so it is not completely out in the elements.

Battery voltage may not be the issue. The issue may be what the amps/wattage of each battery is under load. Have your dealer run a load test on each battery to see if they are up to spec. A battery can show its rated voltage but fail under load. Today I was splitting logs in my pasture and pulled my log splitter and a full load of split oak logs in the bed up a steep bank in 4wd and in low without any problems.
