Style: 12V 100Ah
Very pleased with this battery. Initially used as a solar charged power station, but after setting everything up it seems to 100% operate my electric cooler. Love the Bluetooth connection available right out of the box! Easy to set up and powers a 258wh power station at least 4 times! Battery life is great!

Battery seems to be quality for the price. be careful to size your batteries to provide the current that you need. Only 4 batteries in Series.

I've been using these for a lot more than I originally bought them for. I'll put two in series to a xt60 connector to give a lot more capacity to some devices by plugging it in to their solar input port. With that set up I can get 10+ hours of max usage on a portable air conditioner. For the power hog that type of thing is, that is a great run time and gets me through the night and I can run a generator the next day to top them back up. I'll use them one at a time to power diesel heaters, and just one will run one of those for hours/days depending on how heavy you're using it. And just generally, they've become my goto 12v power station. Even though I have "fancy" power stations. Sometimes you don't need the extra crap, you just want 12v from a device that isn't using itself up trying to do things you don't need. Speaking of that, these do have bluetooth. I was worried about that. I'm not sure what the drain is from that but its not enough I've ever been able to notice it. If I charge them and just leave them be for a while, I think I've done this at least for weeks, its still sitting at 100% the next time I check. They seem to have used a proper lower power draw bluetooth chip in there. I'm not sure if I'll need more than I have, but if I do I'll likely get more of these.

This battery sounded like it would check all the boxes. Cheap, WiFi and Bluetooth, and the ability to put it in storage mode. The reality. 1. Incomplete and inaccurate documentation. Manual says will stay connected with the app, but if it stops charging or discharging, it shuts off and requires a manual button press 2. Cells don’t appear to be matched right. You can’t charge it fully or at the recommended 14.6v, as one or more cells go over voltage. When this happens, the 3 minute timer starts, and the included bw02 shuts down. 4. Per ecoworthy, the bms cannot be updated, so don’t expect a firmware release to fix #1 or anything else. 5. If you aren’t charging or discharging per the listing which contracts the manual, and you try to update the bw02 firmware, chances are it’ll shut it off mid update and brick it. There are instructions to fix it, but requires a windows machine to do so. The window to do this is just a few minutes. Don’t try to update the firmware of the bw02 unless you are charging or discharging. It’ll brick the dongle. 5. Functions in the app itself don’t work, like the “buzzer switch” 6. No documentation for the WiFi up setup or how to communicate with the battery via WiFi outside of the phone app 7. Software on the bw02 advertises incorrectly with the MAC address instead of the manufacturer id like it should, causing BLE issues with any software but their own. 8. The bw02 shuts down based on the columb counter, not actual capacity. As it drifts this means it’ll shut down around 5%, give or take at 12v. If you push the button to turn it back on it’ll keep going until the battery dies. If you start charging it again, the bw02 won’t turn back on until the voltage hits about 12v, which is about 5-8% 9. No documentation about the bms, so no third party apps. Looks to be a different bms than their other 12v 100ah batteries. 10. While the battery communicates via Modbus rs485, the bw02 simply adds on another header when it sends. Since there’s no documentation for the WiFi option, and no bms data, even if WiFi did work there’s no documentation on commands, registers, or coils you can get data from. Overall, if you want this for the capability, it isn’t there. they’ve acknowledged the bw02 and port issues, provide no solution to fix it despite multiple emails, can’t provide any details on the WiFi function, and only state they will look into addressing it on the next version. If you want just a dumb battery, and can deal with never getting full capacity out of it, then you’ll be fine, but then again the non iot variant is cheaper with well documented features. Update: the company did reach out and made things right. It sounds like the next revision to the model will make things right.

Style: 12V 100Ah
I bought the ECO-WORTHY 12V 100AH LiFePO4 Lithium Battery for a project that required a reliable 12V power source. This battery not only meets those needs but exceeds expectations with its advanced features. One standout aspect of it is the Bluetooth connectivity, which allows me to monitor the charge state seamlessly from my smartphone, a truly impressive feature that adds convenience and control over my setup. The only aspect that left me wishing for more is the lack of information on how to develop an application to communicate with the battery directly. Access to such resources would allow for deeper integration into my project, enabling real-time monitoring and control within a custom app framework. Despite this, the battery's overall quality and functionality make it an excellent choice for anyone needing a dependable 12V power solution with modern connectivity features.
