    It seems that most everyone who does this has a different way of doing it. I replaced the eight 6 volt lead acid batteries with four 12 volt 100 amp lithium batteries. They have been installed over six months and have worked very well. I also replaced the Hisun charger with a lithium charger. I also installed a voltage meter in the dash to monitor the battery voltage. In the summer I charge it about once a week. In the winter I charge two or three times a week, depending on how much I use it. I sold the eight 6 volt lead acid batteries for $75. Was happy to get rid of them! Personally, I think Hisun should charge a bit more for the E1 and install lithium batteries in them instead of lead acid batteries. There are several companies selling EV side by sides with lithium batteries that are priced only slightly higher than Hisun!

    I would say that with 305 AH you should achieve your goal and some. I installed a 100 AH system on mine and have more power than I can ever use. The only issue I discovered is that the BMS does not like the brake regen and it cut off the battery. I deactivated the regen system and no more issue. I use a 12v @ 60ah AGM battery for the system's 12v accessories. There is a slight "ghost" currant drain from the Li batteries so I installed a 200 amp cut-off switch on the system.

    On paper that may be so. But I have experienced no limitations.

    It is not just the charging. Inside the battery there many small batteries and they are connected to the BMS monitoring outgoing and incoming flow keeping the small batteries stable. Unless the two batteries were designed to communicate with each other then I would only use one. In normal use I think you will find one battery will suit you well. Now if you were planning to doing a run up Pike's Peak or take an extended off road trip without a means of charging you might have a problem. But the lead acid batteries, when new, could not do that either!

    I agree with GNFO, two batteries connected in parallel would not work unless their BMS could communicate with each other.

    Like so often in these forums folks speculate without actually having real world experience!

    One has to remember that removing the 520 pounds of the lead acid batteries and replacing them with the 100 or so pounds of lithium batteries removes a lot of weight from the E1 and thus giving it more power! One of the reasons the E1 needs to have those high watt batteries is to just help move the weight of the batteries. Without that weight one does not need as many watts. My E1 with the lithium batteries will go faster and climb hills better than the lead acid batteries ever did.

    That battery should work, but you might consider Humsienk's 4-12 volt battery pack at less than $500 from TEMU. They have a five year warranty and are expected to last ten years. Also by going the four 12 route, if you have a failure in one you only have to replace one, but if the 48 volt battery fails, you have a greater expense to replace it. Plus, the four batteries are much easier to install. I have had the Humsienk batteries in my E1 for several months and their performance is awesome. When you go with the lithium battery remember to reprogram your charger for lithium batteries. Good luck.

    One of the issues with Hisun in the US is that they have really poor customer support. My local Hisun dealer does not even keep an EI in stock, and does not even advertise them! As a matter of fact they usually only have one or two of the gas versions. They are primarily a tractor and lawn mower dealer. One has to go to the next town- 25 miles away- to find a real ATV dealer, and they do not stock any electric ATV's. But I am in the middle of bubba country and they buy those big noisy gas monsters!

    Lowes has the Kandi listed for $13k, which seems like a real bargain considering its specs. But it is not available!

    I do not know. It would raise the price. The local dealer only sells the gas Hisun. There is a lawn mower/small tractor dealer in the area that sells a two wheel drive side by side and it has lithium batteries. I do not know the brand but it is light green.

    That just guarantees that the battery pack is grounded to the frame. Like for example, I have a volt meter connected to the + side of the drive batteries, but the negative side of the meter is grounded to the frame. In a car the negative side of the battery is always grounded to the frame and the engine. Many vehicle electrical issues are due to loss of ground somewhere.

    I am not using the Delta-Q charger. I am using an ECO Worthy 48 volt 18amp Lithium charger. Works very well.

    I noticed a bit of a harsher ride so I adjust the springs, which lowered it a bit and gave a softer ride. There is a special tool to do that, but I made one in my shop. There is also a screw adjust at the top of the shock to make the ride softer. Turn the screw to the left-counter clockwise.

    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.
