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: Good battery for emergency and daily use - Excellent battery I use it with a converter and it has worked perfectly for cases of blackouts, charging cell phones. It's easy to connect, very useful practice. I totally recommend it.

### ⭐⭐⭐⭐⭐ Well made batteries at a good price
*by A***L on December 8, 2025*

Good batteries at a good price. One came DOA, and after I got a replacement for it, I finished cracking it open to see if it could be repaired in some way. (Do not do this unless you know exactly what you're doing as it is incredibly dangerous) While what the shipper did to it had unfortunately rendered it unsalvageable, I was surprised by just how well these are made. Ring terminals and screws rather than the poorly soldered connections common on 'budget' batteries, lots of foam padding that is properly glued on, and there was liberal use of some kind of rubber or silicone adhesive on anything that could come loose. I'm pretty sure it had to have fallen out of a moving truck for it to come DOA. As for the functional ones, I've cycled them a few times and even under a decent load they always pull at least rated capacity. But, that is to be expected considering that they're actually 314Ah cells under the hood. Whether that's what Dumfume intended, or if that's just what they got their hands on at the time, I don't know and I'm definitely not about to complain about it. The only issue I have with these is the odd size, and I knew that could be an issue going into it. The only battery box I've found that will fit these without being ludicrously large is a double GC2/Group 24 box, which is still a good bit too long for them. You'll have to do something custom if you want them fully enclosed. All in all though, I would not hesitate to buy more of these or another Dumfume battery. Like I said at the beginning, they are good batteries at a good price.
