Well I called the dealer and he was going to call the UTV Rep. and ask about headlight alignment. I haven't heard anything yet so I removed the assembly to check it out. I didn't see any way to adjust the headlight so I will try putting shims on the top mounting screws which will tilt the assembly at the top, giving me the hight I need . I'm posting a pic of the headlight assembly. I don't see any adjusting screws. Not sure what's under the black plastic caps but it didn't appear to be adjustment screws. Randy -
🙂 No worries. I figured you must have done it properly since you didn't fry your charger or motor controller. Just didn't want someone else to go down the wrong path! Looking at Litime now, I believe I did look at them before, but at the time they didn't have a 48V-class GC2 form factor battery. I believe the ones you have are rated at 80A continuous output, which should give you 320A continuous for the 400A rated motor. Maybe somewhat more since I think I read somewhere that the motor controller can utilize the slightly higher voltage, but I'm too lazy to do the math right now. The ReLion batteries I used are rated at 100A continuous each, which is one of the reasons I picked them, but I think the moments where the motor controller actually pushes 400A to the motor are pretty rare and certainly compared to the Discover cells, 320A is like night and day. -

Im An IDIOT lol i meant Parallel!!!! LOL New to this! and was just too excited it worked! -
Jamie - I'm glad you're happy with your solution, but quick question: You said you wired the four 51.2V batteries in series. That would result in 30Ah of capacity at 204.8V. They should be wired in parallel for the 48V HiSUN system. Are you sure about how you wired them? The Discover batteries were wired in series because each of them are only 6V, so 6V x 8 = 48V.

HiSUNFarmboy - It sounds like you actually had better luck with your Discover batteries than me. I never had good performance up slopes with mine and within a couple years I didn't even dare try going up a slope with a load, which is why I took the plunge for the conversion. I continue to be perfectly happy with the ReLion batteries. I'm sure I don't use mine as much as it sounds like you do, but every time I take it out to crawl around the steep wooded slopes on our 5.5 acres it's been flawless, and on many occasions I've loaded up the bed with split firewood and towed a 5 foot cart also filled with firewood with no appreciable effect on performance. Pretty much all my use is in 4WD Low, but I have been able to hit the 25mph speed limiter on flat asphalt with two people. It can't keep 25mph up a steep slope with two people, but I suspect that's more of a HiSUN issue than the batteries. I especially appreciated that ReLion was able to answer my questions and send me the files to flash the existing onboard charger for their profile. If you go with them, do get their "fuel" gauge, which interfaces with all the batteries through the CANBus (the percentage and amp hours remaining are nice to see), and the remote cable to turn them off/on is a nice to have only because the batteries will eventually turn themselves off if they sit unused for a few days without being plugged in. Of course, if you use it and plug it in every day then it doesn't really matter. Also, four is the minimum I would go with to make best use of the maximum current draw of the UTV motor. If you need more range than I do, you can always add more batteries later (up to 4 more), but since they're fairly expensive I didn't want to pay for more capacity than I needed. I don't know how cold it gets where you are, but if you park your UTV outside all the time just keep in mind that all Lithium batteries have a problem charging below freezing unless there is a supplemental pack heater like EV cars have. I believe the ReLion onboard BMS will stop charging to prevent damage, but it's better if it can be inside a garage and just left plugged in. I think they were working on a version with internal heaters too, but at the time I was looking they didn't have a 48V version yet.
