First and foremost... This is not a high amp cranking battery, it is a genuine deep cycle use limited current LiFePO4 battery. It's rated for about 20amps continuous, and on the first cycle charged back up at 24.7AH which falls right in with it's claim. Much lighter and a bit smaller than a gel/sla, and cycles much deeper. The little meter on top is handy, not sure just how accurate it is just yet. Came with a small wall charger, though I took it right to the bench supply for charging. Out of the box it shipped at about 50%soc and will need charged up. Zero literature packed with the battery, but the front sticker has most of the important stuff. Using this one to keep a 12v refrigerated cooler running in my work van, and it successfully ran it for nearly 20 hours all on its own. Do that with a gel and it would be dead in a month! It's priced exceptionally competitive, and so far works as intended.

Great little battery Works great for intended purpose.

Worked great for two seasons, charged up fully after each trip, and then I fully charged it before winterizing my boat. This year it took a little longer to charge than usual, and then it died within 15 minutes this year. The screen quit working after the first session out, but since the battery kept working I didn't think anything else about it. It won't even take a charge now, and reads 0.00V on my multimeter.

I use this battery to power a 100 watt ham radio in the field. This battery has the capacity to keep going all weekend long without recharging, and still having power to spare. The built-in meter on top is a very handy addition, and the battery fits nicely in the box with the rest of my portable station for ease of transport.

The wires soldered to the a/c charging clips are thin, I have little faith that they will last and give good service. This is a live wire component that by all my experience is guaranteed to fail.

This is the cheapest Lithium battery in the market. I was hesitant to buy but due to its price I wanted to give it a try. I did some comparison tests between this (24AH TalentCell) battery and expert power's 20 AH lithium and Mighty Max 35 AH AGM battery. I should point out that with Lead Acid and AGM batteries, you are not supposed to go below 50% capacity because it cause harm and may reduce the battery's life. The first test was with a hair drier at a low setting with an inverter. It got warm as expected but lasted 40 minutes whereas, 20AH expert power's Lithium lasted 30 minutes and 35AH AGM lasted 22.5 minutes. So if you do the simple calculation by normalizing the rated capacities, expert powers Lithium performed about 2.3 times better than AGM and TalentCell performed at 2.57 times better than AGM. The second test I did was with a projector that draws about 130W and AGM lasted 1.88 hours whereas TalenCell lasted 2.16 hours. Again comparing to their rated capacities, TalentCell performed at 1.7 times better than the AGM battery. I returned expert power and did not do this test with it because it drained completely and the charger did not recognize it anymore, so I returned it. So far I am happy with this purchase although I did not use it for a long time. I hope it lasts as long as they promise. Form my experience Lithium performs much better than Lead-acid and AGM's when the current draw is high. If it is small it is more comparable to AGM but still at least 1.5 times better. Normally I was not supposed to go below 50% with AGM but when the load is connected the capacity shows very low however as soon as you remove the load it shows higher. So in all experiments without load AGM ended up draining at 50%. I hope this helps you understand the performance comparison between AGM and lithium batteries and this battery.

I have had this battery six months. Its weight is good, and it discharges evenly.

Both failed very quickly in low-stress situation, so I think they were from a bad batch. I cut the case off to figure out why, and found the problem was likely in the connectors, because I converted them to PowerPoles and (except for the fact that they don't look nice because the case is off) they are so far working OK. I was assuming that they were working because the setup all tested well when I put it together, but found out when I went back to check (after return window), that they were non-functional. I am actually happier with them now, because: better connectors, I know what they are made properly, and they are slightly smaller in size and easier to work with. I have a solar charge controller that is specifically supposed to both work with these batteries as well as reset the BMS, but they failed anyway, which was why I took them apart to find out. If you are not willing to cut them apart if they fail prematurely, you might look elsewhere, but otherwise they seem to be a good value.
