I have 2 of these for an inflatable fishing boat that I can mount a small motor on the back. I get a solid 3-4 hours of none stop power and once the first one runs out, I switch to the second to head back. I charge them with some small solar panels, which does take several hours but so far the system works great!

Super lightweight and small. This battery is super portable and convenient to move around. Having the screw head threaded posts made it super easy to hook up to. Currently using it in a portable power box that is able to charge my phone, laptop, and other devices. Highly recommend.

The first thing to know is this battery doesn't act like the lead acid family of batteries. with that in mind, do your home work and study up on the characteristics of a lipo 4. they are lighter, charge quicker, and charge thousands of times. They also are shipped drained for safety. when you receive it, it is drained you need to charge it. occasionally they won't recharge, and you need to contact the company as I did. They immediately sent a replacement. i am pleased with my purchase and the seller.

Nice little battery. I’ve attached a solar charge controller with 2 usb ports to it and two cigarette lighter style power points. I also run a 1000 watt pure sine inverter off of it for short periods of time for AC power tools. It’s perfect for powering my Engle freezer. The only issue I have found is that it maxes out its resting charge at 13.3volts rather than 13.6 like my other lifepo4 batteries from the same manufacturer. I’m am using the ecoworthy Lifepo4 10 amp charger so I don’t know what’s going on with this little battery. It would be nice to have Bluetooth option on this battery so you could check charge details like on Ecoeorthy 100 ah batteries, even at an increased price that would be a desirable option. In all it’s a nice compact little battery.

I’ve build a small battery pack for my Jeep using 2 of these to double the amp hours. I’ve been pleasantly surprised at how well they work. I use a 13.1v detector from car batter that turns on to charge this with a dc charger while driving and then i use 12v pigtails to connect to devices to charge or power from these batteries. When i turn off my car and primary battery drops below 13.1 volts the dc charger turns off and these power 12v appliances while parked. As they go on sale i may double up the pack. I also used one to power my fish finder on my kayak. So many uses for these little devices and the built BMS seems to handle the TX heat and mountain cool air in handling charge/discharge cycles.

UPDATE: Was contacted by vendor 11 months after purchase and shortly after my post here. They were concerned about my issue as reported. After several emails back and forth they have sent me a replacement; I received it yesterday. Their customer support was excellent and very friendly. I explained my situation and process and they were not hesitant at all to offer a free replacement. I am bumping my initial rating up from two stars to a full five stars largely due to the customer service and the replacement sent eleven months after purchase. ORIGINAL POST: ... Perfect size and fit for go-to box to power ham radio gear. Sad part is shelf life is terrible. Used three times over past 10 months and had to recharge from 0 volts each time. My other 7.2 Ah backup maintains a perfect full charge over same period. Very disappointed. I may have gotten a bad battery with an internal parasitic drain, way past return window.

Before I begin let me just state that I'm an electrical engineer. I hooked this up to a small winch motor. I ran it for about a minute drawing 20 amps after which the battery started smoking. I turned it off but too late the battery was toast. The over discharge protection never kicked in, and no it's not in a tripped state. Just to make sure I hooked it up to a 15V current limited power supply which would reset the trip had it been tripped. The spec doesn't say what the maximum continuous power dissipation is, but clearly, I exceeded it. The maximum discharge current rating is 25 amps for this battery but probably that is a transitory spec rather than a continuous rating. In hindsight I need a bigger battery for this application, but the spec sheet didn't really help in that determination. Anyway, the over discharge protection should have avoided damaging the battery. But it didn't. So, I basically wasted my money. I reached out to Eco-Worthy via Amazon, but they have not responded after four days.
