36V 100Ah LiFePO4 Lithium Battery 200A BMS,NewtiPower 10000+ Deep Cycle Lithium Iron Phosphate Battery Great for Golf Cart, RV, Marine and Off Grid Applications

I have two 36v golf carts that had 4yr old batteries that all needed replacing. I purchased two of these lithium batteries in May and so far they’ve been great. I was a little concerned about how long the 100ah would last but they actually run longer than the lead acid ever did. The price is much better than lead acid and I think it took about 300lbs off of each cart. Very straightforward install and the quality seems good as well. The carts get used nearly every day at a marina and I’ve never dropped below 40% or noticed any difference in power. Both carts seem a little faster and easier to maneuver which is probably due to the big weight difference. The charge rate is also much better than the old batteries (about 3 to 3 1/2hrs from 50%) I just mounted the chargers beside the battery under the seat and run an extension cord to them, which is much nicer than dragging the old heavy buzz box around. The display is also very informative and shuts down automatically after about 5 minutes if the cart is not being used. Time will tell how long these last but so far I’m very satisfied with these and will never go back to lead acid.

This review is for the Newtipower 36v 100Ah golf cart battery. Since owning my 36 volt golf cart I have been through two sets of lead acid batteries. I felt now was the time to switch to a lithium battery. I tried to contact Newtipower about their higher 133, 166 and 300 Amp-hour capacity, 36 volt batteries golf cart batteries. However, they have no customer support phone number. As a result of only brief email communications, I was left with trying the 36v 100Ah lithium battery for now. This battery came with a 15% stand-by charge so it took 5-1/2 hours to charge up to 100% SOC. The battery charger that comes with the new battery works very well. It cycles off automatically when the battery is fully charged. The touch screen monitor control panel is also very helpful with displaying many aspects of the real time status of the battery. As a result of installing this Newtipower Lithium battery, the golf cart now runs very well when fully charged. It appears that this 36v 100Ah lithium battery has met my expectations of improved capacity over the equivalent lead acid deep cycle batteries. The six batteries I removed collectively weighed 390 lbs. This lithium battery weighs only 58 lbs. So being 332 lbs less of static weight, this golf cart is much more responsive when accelerating and stopping. The following are areas where Newtipower where can improve. 1-The user manual is not technically detailed. It is more a marketing sales brochure of all the battery products they sell. 2-There is a link to download the Bluetooth battery app for your iPhone. However, there are NO instructions or guidance for using the iPhone app. 3-I recommend that there be a much better troubleshooting document specific to this battery. Troubleshooting tips should not be vague and generic to ALL lithium batteries. 4-I would like to see details about best practices for proper lithium battery operations, charging and maintaining this lithium battery. 5-There needs to be instructions for using and configuring the display screens. 6-Newtipower needs a better customer/product support page. Otherwise, I am happy with this battery. I will post a follow up review in about six months.

I ordered this battery conversion kit on February 1st and received it on February 5th. Great service I think. I had watched YouTube videos about installation so pretty much had a good idea of how to do it. I have a 2003 EZGO TXT golf cart. When I received the battery I measured it and found that it fit perfectly in the existing easy go battery frame. The only thing I had to do was grind off the metal in the middle of the frame with the eyelet so that the battery would fit in the frame. The charger sent with the kit actually lined up with a couple of holes under the seat on the driver side and I was able to secure it there. The LED screen that came with the kit was easy to mount as a small metal frame was sent with it. I was able to mount it just under the cubby area on the driver side and fish the cord behind the cup holders and down along the bottom of the frame. I had also ordered a 110 charger port and a plate at the same time I ordered the conversion kit and was able to mount it easily after drilling out the rivets holding the existing charger port. I downloaded the mobile app and registered the battery and charger. I took a brief ride after installation was done and then connected for a complete charge. Everything was simple to do and not time-consuming at all. Update: I recently used my golf cart as a shuttle for a dance from 4:30 pm to 9:00 pm. I still had 50% of battery use left at the end of the night. Very pleased with power and how long it lasts.

I finally received this battery after anticipating its arrival. It came with an LCD screen that I can mount on the dash of my boat. As shown in the pictures, there is supposed to be a port located on the front of the battery where I can plug this in. Unfortunately, there is no port on this battery. Why send the screen if there is no where to plug it in? Why advertise an lcd screen if the battery doesn’t work with it? Why advertise pictures of the lcd screen being plugged in? Extremely unpleased with this purchase as I paid for a battery that was supposed to have these capabilities. I am willing to change this review if this is resolved.

So far so good, I’ve been out several times with this battery running my 36v trolling motor. It hold up very well and barely diminishes under the strain of heavy tidal current. The display that comes with it is easy to read. I use the Bluetooth app to easily check charge levels as well. Highly recommended.

Great solution for golf cart battery replacement

Hold a charge really good. Not as heavy as it looks it was easy to install in the boat. I can use it for three days without recharging it. Use it for at least three hours a day holding the boat over a fishing spot.

We bought this one battery to replace the five batteries we had on our golf cart! The battery last a lot longer and the golf cart goes faster. The instruction were not easy to figure out and took some trial and error to install!
