HiXiMi LiFePO4 Cells 3.2V 54Ah 4pcs Battery Rechargeable Lithium Iron Phosphate,Max.Continuous Discharge/Charge 50A, Support Multiple Series or Parallel DIY Battery Pack with busbars and Nuts

The nice thing about these cells is being able to get them without waiting for a ship to arrive. I got them in around a week. The cells are very carefully packed in robust foam, with inches of protection on all sides, and between the cells. They were all reasonably well balanced, and remain so in service on a JK BMS with active balancing. All in, this route is more expensive than purchasing a 50 Ah battery, but for my situation, it has advantages. 1. I get some experience with a seller. 2. I get some experience with EVE cells. 3. I learn with a modest investment, before moving on to a bigger project (RV solar).

EDIT Sept 15th 2025: Not long after my initial rating, I 'killed' the battery pack.... accidentally left it running my rock tumbler overnight when the pack voltage was below 12.4V, & resulting pack voltage was 0.00V in the morning. I was able to recover the batteries with my charger. I 'killed' the pack one more time about 2 month later & recovered again. SInce then it has been running a rock tumbler almost non-stop. in that timeframe these cells have managed to maintain incredibly tight voltage variance of +/- 0.006V on my Klein MM720 multi-meter, and still charge up to a little over 50,000mAh from 11.2V. Well worth the $$$ IMO. [end edit] I bought these before they had any ratings, which I don't normally do, but thought I'd take the chance based on price per amp hour.... I'm running these in 4S with the included buss bars to power a DC motor that runs my rock tumbler. I'm also using a voltage controller to control the voltage going to the motor thereby adjusting the RPM's of the tumbler. This battery setup will run my tumbler for about 9 days or very close to 216 hours, which leaves the battery pack at about 11.2V - while 10V would be considered fully drained. From 11.2V my charger shows just a little over 51Ah pack capacity! Been using this battery pack for this purpose for about 4months continuously now, and have no issues. Even without a BMS, the batteries keep within 0.002V of each other throughout the discharge cycle. I now finally have a BMS, solar panel & solar charge controller to finally put this whole project together. And hope that this will continue to power my rock tumbler for years to come.

8 - 280 amp hr lifep04 cells recieved today early. The label appears to be authentic. These days there is always the question of authenticity. I ordered these 4 days ago. The date on the QR code was today's date, the 17th. I thought that was interesting. I have a very accurate volt meter. All 8 battery cells received were within 4/10000 of a volt from each other. From 3.2912 to 3.2908 volts. Needless to say I was very happy about that. No bulging. All cells are Brite and shiny. Well done. I am very confident about this purchase.

I just ordered these and I was a bit skeptical because the headline says 32AH but the body of the description says 25AH. Regardless, I received them today and discharged them so that I could do a capacity check. 5 hours into a charge at a 4 amp rate and so far, inbound amperage is just starting to decline on the charger and the capacities are all in the 22k mAh range. Assuming these will still charge for a few more hours at this rate and the final capacity will land somewhere inbetween the 25 and 32 AH range which is acceptable. Update: Added a picture of the charge curves after completion. Need to add 1700mAh to Channel B because I restarted the charge. Whomever commented and said these aren't 32AH doesn't know how to charge a battery properly. In my experience, they are 32AH+ The batteries themselves came beautifully packed in a box with a custom foam insert. While the price isn't as cheap as I would like - so far I am very happy with the purchase.

These things barely made it a year. Every pack is swollen.

What a piece of packaged energy ... beautifully made, four in a box I bought a set of eight with the additional discount. they arrived in one large box somewhere around 35 lb not too heavy to manage. The terminal spacing is perfect when placed side by side with a 2 mm sheet of foam padding between the cells to insulate and allow for expansion when charging. I am fabricating some very rigid 1/8 inch aluminum plates to compress the cells together with threaded rods. this will be one of the most powerful battery packs I have ever constructed. All cell voltages were within 1 millivolts of each other upon receiving. Excellent quality and packaging!

For y'all mad scientist in here trying to bash uncle Bezos affordable lifepo batteries.. these batteries are decent.. bought these 50ah into 72v 24s.. i used a Daly 150amp wifi bms.. i put in this pocket rocket i have with upgraded 80amp controller.. i must say they're not bad at all! Real time A/H is actually reading @ 40ah.. and on my real time test is about 32ah usable.. bike can reach 60kms range at 60kph.. i can shove 2 of these and hit 120kms range! but i aint ballin... bottom line is.. they're not bad for what they worth.. i had 4 bulgy ones and they were warrantied no problem..

Son pocos vendadores que pueden lograr que entran sus batterias a Mexico. Este vendador siempre respondia a mis preguntas mientras que tardaron las batterias llegar x un par de meses. Pero llegaron! Aparecen muy bien, de primera - planos y sin danos. Con mi primera prueba rindio sus 230 ah como debe de hacer. Entonces se puede recommendar muy bien al vendador y sus batterias. Si hubo dos detailes no perfecto 1) no incluyeron las barras y tuercas pero me los van a mandar. 2) Mandaron dos unidades de 3/2023 y dos de 6/2022. Son identicos y funcionen bien, pero quieren balancear. Me indicaron que es un problema con marca Calb pero ya solamente van a trabajar con marca Eve. Lo que aprendi es que mejor pedir todo de misma fecha con fotos de sus etiquettas para averiguar los codigos. Pero al final no hace ningun problema, y estoy MUY contento con la compra. Recommendado 100%.

lo que no me gusto es que tardo demasiado tiempo en llegar, pero estoy solicitando otro producto para ver si mejora el tiempo de entrega.

Batteries were as advertised, packed very well, new grade a cells all balanced

definitely class a cells. all were within class a limits and shipped were within .01v of each other at 3.34v Well packaged in moulded foam. could probably have dropped them and no damage..
