TalentCell 12V Rechargeable LiFePO4 Battery Pack with Lithium Iron Phosphate Technology

RB855RB855: 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.

Opa S: I loved the builtin meter, 24 AH capacity and the price. The intended use of this battery was to be as a portable off grid power source for emergency amateur radio communications. I could not comfortably lift and carry it for any practical distance as it is too heavy and too wide to grab with one hand. It would be perfect if it had an appropriate handle. I returned it and bought a 20 AH battery that is 1" narrower and almost 2# lighter.

a speros: I bought 2 of these for an indoor project they work well I expect with the load I put on them they will last a lifetime. just remember a 20 max output 10 amp charge and they do not have cold temp charge cutoff charging them in freezing temp could destroy them, and as far as value.. over the past year prices have come down. Today I would buy a larger battery with higher capacity for the same cash I spent on 2 smaller ones, better current capacity and bigger batteries generally have better bms that includes low temp cutoff. I don't actually need low temp in my application but having it means it can be used for other projects down the road. since a modest load/charge cycle mean lifetimes that can span 20+ years.....

G. Spiers: 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!

Vanessa O.: 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.
