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.

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.

This has been a solid solution. I've been using a pair of them to power my diesel heaters this winter without problems. I have four 100w solar panels and have experienced zero issues. I contacted customer support with questions and received a prompt and well informed reply. Good product, good company. A good value.

Using this battery for solar and backup power in my rv. Runs great, can pull full power. This has a small daily cycle of about 20% on solar, but when the power is out I have had it run my camper and keep the lights and internet running for almost 10 hours.

this is a replacement unit I purchased after the first one failed to recharge due to its faulty cold temperature charging protection. It is a great value for 300ah battery for only $300. It worked well for me until it stopped charging at the freezing temp which was a feature. However, even after the temp bounced back to 40Fs it wouldn't charge. Finally after the temp hit mid 50Fs it started charging again. Needless to say, the defective unit had to be returned and now I have a new unit. I will report back if there is the same problem.
