24 AH battery-Use it to power a Icom IC-7000 mobile amateur radio without issue
This is probably the smallest lithium iron phosphate battery that can power an Icom IC-7000 radio without issue. The radio requires at least 20 amps continuous power and smaller lithium power sources fold at much less current requirements making this battery well suited for a small form factor no compromise full power out from a mobile radio in a portable environment. I haven't checked the capacity against manufacturer specifications yet, but appears to be close due to the charging profile. The battery gauge is based on voltage, and not a actual coulomb counter. For a more accurate battery gauge, I would suggest one of the coulomb counters with the green backlit LCD displays with the brass shunt. They can be found here on Amazon and ebay. We'll see how well it ages and I'll report back sooner than later if I encounter any shortcomings but so far it's good! Update: Verified battery capacity. It is witihin .5AH of rated specifications. I was able to sustain full power out of my Icom HF radio up to about 1.5AH left in battery, then I saw the voltage drop off considerably. I'll dial into my coulomb counter a 20AH capacity limit so the depth of discharge is around 83% which gives me that "emergency reserve". ... show more

Impressed so far
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. ... show more

Highly cost effective and does what it says.

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. ... show more

Dead after 5 months
I bought one of these early October 2021 and was happy, worked well and much lighter than a lead-acid. I either charge using a dedicated Li ion battery charger (home) or using a solar panel with charge controller (camping). Amazon return cut off date was Jan 31st. It’s now Feb 21 2022 and I’m getting ready for a trip and the battery voltage is 0V. Going to try to contact the manufacturer. Manufacturer got back to me quickly and asked about my charger but nothing but crickets since! ... show more

Good Value (24Ah model) - using 2 and 4 in parallel
Review Image by W. Lange
I have used lipo for my RC aircraft for some time but this is my first experiment with LiFePO4 as a 12 volt battery. I am using my SkyRC D400 charger which has a LiFePO4 charge mode which can charge up to 20A on one channel. I recommended a charger designed for LiFePO4. So far I'm very pleased. I am using two of the 24Ah in parallel as shown for effectively a 12v 48Ah battery. I have another 2 on order to make another 48Ah setup. This way I can use each of a 48Ah amp hour individually or connect them together to make a 96Ah 12-volt battery. The price cames out to be about $670 for all of four which is cheaper than most 100 amp hour LiFePO4 12-volt batteries. I've tested my 48Ah delivering 40+ amps easily although spec I would caution you to limit 40A (2 x 20A - parallel connection doubles the available amperage). These will be a backup recharge solution for my EcoFlow Delta battery/inverter and for mobile RC battery charging. ... show more

A/C charger wires to clips are thin, guarante to fail
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.

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. ... show more

Good value for the Price - 20AH Battery
Although this battery does not have low temp cutoff, or so I read somewhere, I am not going to try to charge it at low temperatures. It is working very well for my purposes of running ham radio equipment from DC. I still need to charge it from solar panels, charging it from an AC outlet with the proper charger works great. I like how light it is compared to the AGM batteries I used, and still have. I will take this one with me for portable operations. The AGM batteries will be used at home, until they die. For QRP operations other hams have also recommended TalentCell batteries of lower amperage. Only long-term use will determine if it lasts 2000 cycles, of course, with proper care. ... show more
