Dumfume LiFePO4 Battery Series 12.8V 50Ah 12.8V 300Ah*2 PACKS 12.8V 300Ah 25.6V 100Ah*2 PACKS 12.8V 100Ah *2 PACKS 12.8V 200Ah 12.8V 600Ah Review: a good no frills lifepo4 battery - I have purchased a total of 4 batteries. 2 from desertcart and 2 from the dumefume web site directly. they were purchased 1 battery a month. first and last purchases were from desertcart. the 2 that came directly from dumfume had a 13.0 and 12.9 volts. they both charged to 100 percent with no problems. the 2 that came from desertcart had 12.2 and 12.4 volts. they would not charge. i hooked another fully charged lifepo4 battery in parallel to the non charging battery. i then hook a 20amp charger to the non charging battery. it then charged fine. i waited 24 hours then recharged each of them. i was surprised that it took another 10-15 minutes of 20amp to top of all 4 batteries. This process was done when each battery had arrived. note that one of the batteries from desertcart came in with a hole in the box. the battery appeared not to be dented or damaged. PRO: 1: this dumefume 150ah lifepo4 battery is priced good. 2: i like the fact that it is not a smart battery. i have no cell phone and did not want or need the blue tooth feature. 3: external seems to appear to be well built does not feel cheap. no clue on interior. 4: they are light weight for the size and amperage of the battery. CON: 1: did not like the fact that i had 50% of the batteries were not able to be charged and needed a "jump" charge from another battery to get it to work. a little concerned on the bms settings because of this. i also wondered if this was caused from used cells or not. 2: no more room in the house for another battery purchase. NOTE: i have purchased these batteries to supply additional power when attached to a power station. they work great in recharging those power stations. these batteries are being used a power storage and will be sitting on the shelf for an emergency. it will be interesting to see how they hold up over time. i would have liked to see a teardown of the 150ah. there are a few online for the other amp hour versions. CONCLUSION: i like this battery. its a new frills, non smart lifepo4 that feels good to hold. dumfume does have good deals both on desertcart and there website from time to time. If i had room in my home and/or needed another battery i would purchase it again. only minor issue is the charging of this battery and long term (calendar time) will "age" well. i am happy with the purchase. Review: Very satisfied with these batteries - I have four of the 150ah units and am extremely pleased. All have exceeded rated capacity by about 7ah when new (makes sense as this is basically 1/2 of their 314ah battery). I have to physically carry the battery from point of use to charging station- approx 100yds each direction across uneven ground. I could do it, but it wasn't the favorite part of my week. I needed easier portability than I had with my 300ah (non Dumfume) batteries that weigh between 66# -72#, and these 150's weigh in at 24.5# and are easily moveable. I have an older160ah battery from another brand and it weighs 37#, and my shoulders can really feel the difference that extra weight makes. I've been impressed with the quality, and they are working well in my application. I charge at 50A using a smart charger usually and they seem to like that rate, and I have never had an issues with getting them to accept charging when new. My oldest Dumfume battery is about 1 year old and after a year of twice weekly charging, it still exceeds rated capacity, so I'm expecting good things from all my Dumfume batteries. So far, so good. Simple battery. High value. And in my case, life improving. Lastly, one of my batteries came in damaged, appearing to have been hit by a forklift fork that sliced through the box and cracked the battery case. Dumfume sent a replacement quickly with no hassle at all. Very pleased. I'll be buying 12 more batteries over the next couple of months (4ea-150/314/600ah) and unless something changes, Dumfume will be my go to for all of them. ## Features - You will receive:DUMFUME 2 pack 12V 50Ah LiFePO4 Batteries.The single piece measures 7.72x6.57x6.69 inches and weighs only 11.5 pounds, making it ideal for portable applications such as RVs, camping and home energy storage.

I bought them for my home solar setup with an inverter and solar panels, and honestly, they have exceeded my expectations. The 24V 100Ah capacity is definitely noticeable. They provide very stable power and last a long time for daily use in my system. Connecting them to the inverter was simple, and everything worked smoothly right from the start, which I really appreciated because I didn’t want any complications. While I was away, it gave me peace of mind knowing the system would continue running reliably, and when I came back everything was still working perfectly. So far, they’ve performed extremely well and feel like a great investment for my home. The only thing I would improve is including a more detailed instruction manual for people who are not very experienced with solar installations, but aside from that, I’m very happy with this purchase. I would definitely buy them again. ## Frequently Bought Together - Dumfume 2 pack 25.6V 100Ah LiFePO4 Lithium Battery, Built-in 100A BMS, 2560W Power Output, Up to 15000 Cycles, Ideal for RV, Marine, Trolling Motor, and Solar Off-Grid Systems - ECO-WORTHY 2pcs 100 Watt Solar Panels Monocrystalline Solar Panel for 12V/24V Battery RV Marine Boat and Other Off-Grid Applications, 2-Pack 100W - BougeRV Solar Connectors Y Branch Parallel Adapter Cable Wire Plug Tool Kit for Solar Panel --- ## 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.sn/products/723468449-2-pack-12v-50ah-lifepo4-lithium-battery-built-in-50a](https://www.desertcart.sn/products/723468449-2-pack-12v-50ah-lifepo4-lithium-battery-built-in-50a) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
