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! ### ⭐⭐⭐⭐⭐ Lots of power and features in a compact size. *by B***. on August 19, 2023* 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. ### ⭐⭐⭐⭐⭐ Best value *by H***E on March 4, 2025* 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. ## Frequently Bought Together - 12V 50Ah LiFePO4 Lithium Battery 50A BMS,NewtiPower 10000+ Deep Cycle Lithium Iron Phosphate Battery Great For Winter Power Shortage, RV, Marine and Off Grid Applications (12V 50Ah) - NOCO GENIUS1, 1A Smart Car Battery Charger, 6V and 12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Motorcycle, ATV, Lithium and Deep Cycle Batteries - Newport NV-Series Thrust Saltwater Transom Mounted Trolling Electric Trolling Motor w/LED Battery Indicator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/595382230-12v-50ah-lifepo4-lithium-battery-50a-bms-newtipower-10000-deep](https://www.desertcart.jp/products/595382230-12v-50ah-lifepo4-lithium-battery-50a-bms-newtipower-10000-deep) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-17*
