I ordered this battery to power my ResMed 11 CPAP during a two-night weekend backpacking trip with this 12v CPAP power adapter: https://www.amazon.com/dp/B0C3R1N46D. What I have noticed over time is that about 1AH of power in a LifePO4 battery provides about 1 hour of power to my CPAP (without the heater turned on). CPAP heaters are a no-go for any battery-powered solution.This battery offers 2 nights of use, plus an extra charge for my iPhone 14 Pro, all in a relatively lightweight 4-pound 7.2-ounce package. To charge my iPhone, I use this product: USB PD iPhone charger https://www.amazon.com/dp/B096FNQWWJ.Charging capacity and drain for this LifePO4 battery seems to be in line with other LifePO4 batteries I’ve used in the past. A week after charging this battery to 100%, it shows 13.3v based on this voltage meter: https://www.amazon.com/dp/B096FNQWWJ, which I also keep attached to the battery through a harness as shown in the attached photo.The size of this battery maxes out the space I am OK with using in my 60L backpack. It fills a gallon ziplock bag, and the ziplock bag barely closes to give a sense of the size. I would have liked a smaller battery and could have gone with two 10AH batteries, but that would have come at a compromise of charging speed and weight; two 10AH batteries (any brand) would weigh more than this single solution. A significant advantage of this battery compared to lower AH LifePO4 batteries is the built-in 30Amp BMS. This feature allows for recharging over a long lunch, unlike the much longer 5-10Amp charging limits of smaller LifePO4 batteries, which can take a couple of hours.During testing, this battery successfully charged and handled two nights of CPAP usage. The charging speed and power output seem to be holding up well, and I plan to continue testing it on future backpacking trips. Overall, this LifePO4 battery is performing well and deserves a 5-star rating and is recommended for 2-night weekend backpacking trips.

Used on a backup house generator. Plenty of power and plenty of reserve for starting in bad weather. These units last years longer than lead acid batteries.

The display only shows volts which is pretty useless on this type of battery.

Wonderful battery.Used this battery to replace two traditional smelly ones. Right away, could start the RV generator without having to power up the RV. Only one battery is necessary , if it remains as powerful as it is, I will be thrilled.

I swapped in this 7Ah battery from a 10Ah I had been using on my solar lighting project, and it seems to work just fine. My lights run all night long, and it was fully charged by just after noon, which is just as my 10Ah had been doing. One thing of note is it seems to charge to a lower voltage, at 13.57V where my 10Ah charges to 13.95V. That may be due to the different BMS, and charging to a lower value may extend it's lifespan, so I am happy with that. The quality seems pretty good, and it's weight feels right for it's size. I feel it is priced fairly for a 7Ah battery and is a fair value.

I’ve Only had it for a couple weeks still running some tests on it to see if the capacity is right or close. One thing didn’t come with any booklet of directions , Specifications /troubleshooting if something went wrong…. be good to have to point me in the right direction If need be.
