    • Great batteries for the money
I used these batteries to upgrade 7 years old solar lights batteries that needed for new batteries. It's little larger than what original ones are, but what I gained in lighting time is remarkable. It literally works 4 nights, 8pm to 7am. Battery life is crazy. If I need to buy more, I definitely will get this product. ... show more

    • Solar light batteries
One of the batteries went dead within a couple of months, I asked supplier for an exchange twice. I did get a response from them. Life po batteries are supposed to last ten years.

    • These work very well
For: CITYORK 4 Pack 3.2v 32700 LiFePO4 Lithium Rechargeable Batteries Bought these to replace the manufacturer-supplied ones in my solar, outdoor driveway lights, which failed within a couple of years. These work very well after I soldered thenm in. I cannot comment on how long they will last, since I just bought them, but , if they work longer than the originals did, I will not complain. Update: Jun 2025 and the batteries do not hold a charge at all, despite being placed in full sun for over 2 days. Reduced my rating from 5 stars to 1 star ... show more

    • Good, but not 7200mAh (7.2aH)
I used these cells to build a custom 12V battery pack for a portable radio repeater. Cells are arranged 2P4S. Test Parameters: - tested with West Mountain Radio CBA-V - 1A current draw (0.07C based on "rated" capacity) - test stopped at 90% DoD (12V) - test result : 8.756aH -- Most radio equipment starts to struggle below 12V, so this is the usable capacity for my application. Doing the math (8.756aH / 0.9), my battery pack rates at about 9.7Ah. This is in line with what other reviews have noted - these cells are good for about 5Ah. I knew this before I bought them, so I'm not surprised. But yeah, 7.2Ah these are not. ... show more

    • Not 7 Ah cells
I can get at most 5Ah out of it, but that consistent. Cycles it about 50 times always the same result. I kept it because the individual cells allow me to create my own layout. Combined with a 30A BMS makes a small pack for portable ham operation in a 3D printed housing.

    • No way to contact seller, 1 bad battery....
Review Image by Web Geek Web Geek
I soldered leads on to the batteries and hooked them up to my charger/discharger this evening. Assume they had a "storage" charge on them as customary for LIFEPO4 batteries. Upon discharging them, was pleasantly suprised at well over 4800 mAh of capacity. Charging them now, but one of the cells is misbehaving - it went from constant current to constant voltage charging after only 1000mAh - which means the end capacity will be significantly under what is advertised. The other three cells are still at constant current of 2A after over 2,000 MaH - so the capacity on these will be exactly as advertised. You can see what I am describing in the attached screenshot from my charger - Channel C is a "good" battery, still charging at 2 amps after a full hour, and Channel D is the "bad" battery, which has already dropped to constant voltage charging after only about 40 minutes. Wanted to contact the seller to see if I could get a replacement for just the one defective cell, since I have already soldered leads on it - but there is no way to contact this seller. You have to go through Amazon, and they want you to return the whole kit and kaboodle, which, since I've already soldered leads on the batteries - isn't really an option. I don't see the point in sending three good cells to the bin just cuz one is misbehaving. So far - 4/5 stars on the product.... 1/5 on customer service. ... show more
