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: Excellent Battery at a good price. Massive power for my RV from two of these 300 AH batteries. - FYI - I am unable to see the negative reviews on this product and getting this on many other products too; the 1-star reviews cannot be seen by customers. Maybe its an desertcart glitch, not sure. However, the seller delivered on time, at a good price, and a good product, no issues there. Please fix the review issue! That is not acceptable. I have installed these batteries and they work very well. Initially, I saw a Deep Discharge msg on my Victron Battery Monitor and got worried, but my solar installer fixed the software issue with a reset. Now they show 100% capacity, it all works extremely well. Why did I pick the Dumfume LiFePO4 Lithium 300 AH battery over others? 'Project Farm' channel on Youtube did an in-depth review of various Lithium battery brands and this one came out high on the list, with a low price tag. He cut them open too, so you could see the build quality inside. Dumfume had the best build quality inside, all correctly assembled, no shortcuts. Along with all the other metrics tested, and the decent price, I was convinced this was a good battery. Only time will tell in the end. But at present, I can attest this is a solid battery, delivered well packed no damage, and timely delivery. Very happy customer. Please fix the reviews issue. I have a Class C RV, older 1997 model, Ford E350 V10 6.8L engine. 22 ft long, 12 Volt 30 Amp System in RV. I have a Victron Multiplus 2 Inverter/Charger, 2 Dumfume 300 AH batteries, 800 watts solar panels (200 W each from HQST Solar), Victron MPPT 100/50 (maxed out at 800 watts solar). This system is giving me more power than I need. I can run a residential 7 cu ft fridge (no freezer) easily without a dent in the power. I plan to upgrade to a 10 cu ft Insignia residential fridge. It is summer in CA, so plenty of sun. I also have an alternator Orion device so it will charge as I drive. These specs in case anyone needs them. Two of these batteries at 58 lbs each and 300 Amp Hours weighs less than a standard AGM 100 Amp Hour battery that weighs 65 lbs. Lithium can discharge 80% before it reaches critical stage, whereas AGM (Lead Acid) can only discharge 50%. The price of Lithium today is actually less than AGM. So no reason to not switch over to Lithium. Know too, that the old Progressive Chargers that are factory installed in these RVs are absolute rubbish and only float batteries, never fully charging them up. So your batteries die. They also cannot handle lithium. You must changeover to a whole Lithium system, it is unbelievable. My cost was $3K for all the components approx, and $4.5K for install labor including a little fan to vent out the heat. Under $8K is a great deal. I plan to travel and live full time in it so it will save me money in the long run.

## Questions & Answers

**Q: Any tips for connecting batteries in series or parallel?**
A: Yes – fully charge each battery first. Use the same brand, model, capacity, and BMS, and buy them within 3–6 months of each other. For multiple connections, use a bus bar.

**Q: Can I use the battery right after delivery?**
A: For shipping safety, it comes with ≤40% charge. Fully charge it before first use.

**Q: Can I use this battery on a boat?**
A: Yes, as a service battery for things like a fridge or coffee maker. Keep it dry and away from water. Not for starting engines or trolling motors.

**Q: Can I charge or discharge it in cold weather?**
A: Discharge works from -4°F (-20°C) to 140°F (60°C). But never charge below 32°F (0°C) – it damages the cells. The BMS will block charging. In winter, bring it indoors above 41°F (5°C) before charging.

**Q: Does the package include a LiFePO4 charger?**
A: No. Please use only a dedicated 14.6V LiFePO4 smart charger. Using a regular lead-acid or other lithium charger can damage the battery.

### ⭐⭐⭐⭐⭐ Reliable Power and Peace of Mind for My Solar Setup
*by A***E on May 26, 2026*

I wanted to wait a little before leaving my review because I had been traveling and really wanted to test these batteries properly before recommending them. 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.
