Size: 12V150AH(12.8×6.5×8.46)
I have purchased a total of 4 batteries. 2 from Amazon and 2 from the dumefume web site directly. they were purchased 1 battery a month. first and last purchases were from Amazon. 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 Amazon 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 Amazon 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 Amazon 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.

Size: 12V150AH(12.8×6.5×8.46)
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.

Size: 2PCS 12V300AH (314Ah) (15.16×7.6×9.84)
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.

Size: 2PCS 24V100AH(21.06×8.07×8.46)
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.

This is a review after using the battery for just over 1 year. It's dead, It started failing to supply any kind of useful power in my campervan. Would gradually go dead overnight with only a 3.5 amp draw on the battery from a 12vdc refrigerator. The solar panels would recharge it during the day but it kept charging to a lower value every day. I put a 10 amp LiFePo4 charger on it at night to help but it would only charge to 13.2 vdc. Today it drained totally in within a couple hours of the sun going down. I believe the BMS is in low voltage cutoff as it outputting nothing. Disconnected all loads and then connected the charger but so far it does not seem to be taking a charge. Very disappointed because up to this point it had performed very well. So the rating goes down to one star. According to Dumfume's website the 5 year warranty is only for batteries purchased from them directly, not through Amazon. So one star it is... Early review since I just installed it. It arrived very well packaged and on time. Came just slightly discharged as expected but once installed in my system the 500 watt panels brought it up to full charge within a few hours. Have not tried to seriously discharge it but it keeps my Bodega 12vdc refrigerator and 800 watt microwave powered without issue and recharges quickly once the sun comes up. Came with extra bolts and plastic color-coded protective bolt covers. Quality seems to be excellent. I purchased it based on a review I watched on Youtube that involved a full teardown and full charge/discharge test that also tested the high/low cutoffs for charging and temp over limits. It passed all tests…

Test of 1200 watt Ampinvt low frequency inverter supplied by Dumfume 100 AHr lifepo4 bubattery operating 8000 BTU Midea inverter window air conditioner. Load is 35%. Battery arrived with good charge. Does a good job. Inverter is $165, battery is $150. AC uses 435 Watts at 107 volts. 4.8 amps. This is just a trial for an installation into a cabin bedroom. Just FYI if you want to set up a least expensive power option. 👍🏻

I've received this battery in a good package 📦, well put together..it work well I charge it first thing, think it took about 9hr or so to full charge, some how it limits me (BMS) only to ONLY A 12OO/1300 WATTS draw.. which is not what, I expected.. with 200amp bms, ive 2500watt inverter..

The battery is advertised at 48v 100 ah. When received, I charged at a constant current, constant voltage, with a desktop power supply set to 58.4v and 5.0 amps until the BMS shut down the charge at 55.2v. I then discharged at a constant current of 2.75 amps DC (well within tolerance). The batterys BMS shutdown the discharge at 52.5v well before the max discharge of 40 v and only allowed discharge of 78 ah total. A second test was run yeilding almost exact result. The vendors replys were all met with exact answers and additional testing but all they claimed was that was acceptable due to line loss and inefficiency. 22 Ah losses are not negligible, and i did not utilize any dc to ac conversion or high discharge rates, nor did i have large line losses though 12 in of wire at 2.75 amps, and i feel their is something discrepant, or the battery was mis-represented in the ad. Beware no returns are accepted sobif you get a bad one you are out 600+ dollars without any recourse. UPDATE The seller eventually sent a return shipping lable to correct this issue. Prior to returning, i decided to cycle the battery fully a few more times, and low and behold, the bms began to function properly. I am now getting the advertised output, (actually better 106ah). Needless to say if it keeps functioning as advertised this is an excellent value.
