I have tried the battery reset. After some research on the gas Hisun repair manual, that except for the gas engine, is basically the same as the E1, I believe it is in the front differential servo. That is the device that connects the driveshaft to the differential.

Yes it is much better then the factory option Kioti offers. They break off once you hit a tree branch. Very poor design! But this option works very well.

He seemed to think the cables were fine. I think he has a particularly long hill he always has to use and he was reaching max on the motor output. It's in this thread Posts #52, 54, and 61 lay out his problem and troubleshooting. Worth coming back to if you have problems. I believe his Allion GC2 batteries have a listed max continuous output of 60A, 65A for 30 seconds, and 100A for 10 seconds. It probably comes down to variances from battery to battery and how good the BMS is at keeping discharges equal between all of them.

Funny, I never realized that the actual values are a 10x factor! Yes, it was reading around 300 amps; wow, that's a lot of current! Well, despite it showing 300a for 20 seconds or so, there were no errors. Aside from the difference in batteries, I'm wondering what gauge wire BuggyBoy used, as that can also be current limiting, but not sure if that would have contributed to triggering an error.

For me the Hisun dashboard seems accurate when it works, but sometimes it seems like it doesn't show anything at all, including speed. Probably not related to the batteries as much as a finicky dash display control board. I haven't bothered troubleshooting since the actual operation of the UTV is always fine. When you say 30-35A draw displayed, do you mean the needle is just barely moving up? Because the dial itself is of course "x10A" so the number "30" is actually 300. Going up hills I find the draw is usually 200-300A, so if the draw shown really was indicating only 30 that seems low.

Thanks for that info! In my limited testing so far, I did go up a fairly steep hill that took about 20 seconds from bottom to top (which was a few seconds faster than with the AGM batteries), and did not have any errors in that case. The original onboard current gauge was only showing a 30-35 amp draw, but not sure if that gauge is accurate with the lithium batteries. The LiTime gauge does show amp draw, but it was very small and hard to see as I was climbing the hill; I'll try that again one day. Most of the the use for the cart is on my property, which has some mild, but not steep hills, so hopefully this will not be a problem! I hope not, as I would rather not spend the additional $ on more batteries, but that will be be determined.

Something to file in the back of your mind if it comes up, BuggyBoy (who's in Australia and used a different battery maker) ran into some problems with his four batteries becoming unbalanced and throwing some temporary charging errors because he was exceeding the max amp output of the batteries for too long (I think he has a pretty long hill). He laid out the details recently on one of the other battery threads here. Along with not being many options at the time, one of the reasons I went with my battery maker despite the cost was that each battery was capable of 100A continuous output to match the max motor draw. I believe your LiTime batteries have a max continuous output of 60A, but are rated to put out up to 120A for up to 5 seconds and up to 300A for up to 1 second. So with an (on paper) max continuous discharge of 240A (4 x 60A) you could potentially overdraw on the batteries if you have a steep, long hill. Depending on your use and however much of a safety margin their engineers designed in you might be fine, but just keep in mind you might have to add as many as 3 more batteries to hit a max continuous output of 400A. The upside would be that if you do have to do that, you'll have that much more total capacity (range). Just wanted you to know.

Updated profile, burned wire replaced, first battery connected, CAN port connected to digital LCD screen; everything looks good so far. Glad that onboard charger didn't appear to burn out due to whatever caused the burned wire.
