So glad I purchased these for my trolling motor. The weight, fit, ease of installation, and battery life are all very good. The built in battery meter is also a plus. The price was the best by far compared to other brands.

I couldn’t be happier with the NewtiPower 12V 600Ah LiFePO4 battery! It integrated seamlessly into my van build and has completely exceeded my expectations. With its compact size and lightweight design, installation was a breeze, and it fit perfectly into my setup. What really impressed me is its performance—this battery gives me 5-7 days of reliable off-grid power without even factoring in solar or alternator charging. The capacity is truly as advertised, and the built-in BMS ensures peace of mind with its intelligent protection features. It’s clear that NewtiPower put a lot of thought into creating a product that balances efficiency, reliability, and ease of use. Highly recommend to anyone looking for a high-quality lithium battery solution! Will update with installation video and wiring diagram.

These batteries are the best around. I have owned 4 200 Ah ones (10 kWh at 48V) for several years, which I used for an off-grid solar system out in the Texas desert. They have survived temperatures from 10 degrees to 120 degrees F (even hotter in the shed they were in) without any issues. I just bought 8 additional 300 Ah ones (another 30 kWh) and installed half of them. It is amazing how they can take or produce kWatts of power and not even heat up. The 300 Ah ones were cheaper and more compact than the old ones per kWh and they now come with a handy built-in Voltage and State-of-Charge meter. One thing to keep in mind when installing: use short, thick cables, preferably 1/0 AWG copper or better, and quality lugs. 100 or 200 amps is a lot of current! The batteries were delivered within a week from ordering and were very well packaged. A true quality product!

Our old lead acid batteries in our camper will no longer hold a charge. I have been searching for a LiFePO4 battery for some time and could not find the perfect one until I discovered this one. The stumbling blocks in my search were that many of them do not have low temperature cut off which is important to me because we occasionally camp in cold weather, or they were too big to fit in the standard 8" wide frame welded into our camper, or they were way too expensive. This battery checked all the boxes. This 200ah battery weighs just over 47lbs and replaces the pair of 100ah lead acid batteries that weighed 40lbs each, giving us the same or more capacity while only weighing roughly 1/2 as much. The photos show the old set up compared to the new. I did still struggle to find a battery box that this battery would fit in, and still fit inside my camper frame rails. Part of the problem is that the measurements of most batteries and boxes are too general making it difficult to tell if they would fit. In most cases the measurements are different at the top than at the bottom. This battery measures 13 7/8" L x 7 1/4" W at the bottom and 14 7/16" L x 7 1/2" W (including handle protrusions) at the top. The case measures 9 3/4" tall plus the terminals will stick up above that. I ended up using the Camco double battery box #55375 also purchased from Amazon. As you can see, everything fits together perfectly on the standard 8" wide camper frame rails. (I did have to cut out a divider that was between the original battery boxes on my frame rails). The extra space inside the battery box will provide room for the TPMS transmitter, battery monitor shunt, terminal blocks, and main disconnect switch. It will also allow a much neater wiring installation. Our camper's electrical system was designed for lead acid batteries and will not properly charge LiFePO4. I have been in contact with the camper power center manufacturer, WFCO, who makes an updated converter that will replace ours and I will be changing to it. Since it will be a little while until I can change the camper converter, the folks at NewtiPower were kind enough to send me a separate charger at no cost so I can use their battery in the mean time. NewtiPower customer service has been fast and has exceeded my expectations. I am very pleased with their products and service.

This battery works great for my 30 lbs thrust trolling motor on my canoe. Could do 2 or more days before needing to charge. I also use it to power my 12 vdc fridge. The display showing the amount of battery left is nice.

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.
