Excellent batteries
The batteries are excellent, exactly as described and the seller provided ‘above and beyond’ support. Extremely happy with this purchase. Highly recommend!!! Update - we purchased four of these at the same time and connected them in parallel. After using these on their first 6-day camping trip and powering lights, appliances, water pump, etc., in our rv, they were excellent and exceeded our expectations. They seamlessly ran everything without any diminished performance. They were easy to charge with the Eco Worthy charger which is connected to the batteries and our generator. They were fully charged each day in less than two hours of running the generator. Highly recommend!

good with Bluetooth connectivity.
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.

Light and good. Perfect for the kayak
Decided to go with this battery and this seller. When I was looking for a kayak battery, I sent messages to 4 different brands and sellers. ONLY this one responded overnight and fully answered my questions. Easy to deal with. The rest kept telling me generic answers and nothing to assure me that if something goes wrong, I will have a good post sale service (warranty service). Great voltage, great power for my kayak, very light. I fully charged the battery with their eco-worthy charger. Charged it fast and battery tested good. Used it once for probably 3 hours trolling. Used very little power. After 2 months of sitting in the garage it is holding charge very good. Battery charger shows accurate reading when I checked with the voltmeter. Happy with battery and the seller.

TLDR; not worth it and unfixable
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.

Easy to install, highly recommend.
bought on sale and got a great deal. It was actually the same price and replacing my lead-acid RV battery, so the switch over was a no brainer. The battery is very light, and was a direct replacement with my power converter. The app loads up quickly and cleanly, and allows you to look at every aspect of the battery, including the individual cells. So far, a perfect replacement for an aging AGM. The only "ding" on the battery.. it was sent with a full user manual for the APP, but not one for the battery itself. The battery manual has to be downloaded from Eco-Worthy's website.

Eco Worthy 100ah LifePo4 (with Bluetooth)
This battery is performing flawlessly. I use it to power an electric trolling motor on my small boat. I've used the motor for the better part of a day to explore local lakes. With the Bluetooth capability I can quickly check to see how much charge is left which is a nice feature when you're a long, long way from the boat launch. With almost constant use one day, the battery still had 83% charge remaining. Truly amazing, especially when compared to the lead acid batteries I utilized in the past.

手早く、親切で助かりました。 実は幅が26cm級で高さ奥行きは一般のLifepo4と同じものでは稀有です。 エネルギー密度が向上しており、セルのクラスが違います。 通常は幅33cm級で高さ奥行きは共通というのが大概です。そして11Kg近くあります。 7cmも違うんです。 つまり21%もかさが違います。 しかし、価格帯は一般的な大きいセルと同じかわずかに高いくらい。 加えてサポートが早く親切。 これを選ばない理由なんてどこにもありません。 たとえ1000円 5000円違いなんて永いライフサイクルを鑑みると豆粒なる誤差と思います。 LitimeさんのMiniは133*228*260mmと当品物から更になんと24%小さいも幅は260で同じながら奥行き薄くなって高さはアップなので専用に積むスペース設計を考えないといけませんが、うまく収まれば強気価格設定もトレードオフできるくらい素敵かと思います。 取っ手もとっても良くて高さ、幅、奥行きの中にきっちり納まるので、箱状のものに並べて積んでもスッキリ。 従来の100A級の置き場所に並べていくと幅だけ余るので、何か設置する余裕がまさに一個につき嵩の21%分生まれてくるのでありがたいです。これは複数個詰んだ時に更に良きと思うはずです。 もっと、大きさや重さが素敵という利点を押し出して販売すればいいのになぁとも思いました。

鉛電池からの買い換えで、何と言っても軽さは魅力的 まだ3回ほどの充放電であるが特に問題無し インバータが低電圧でカットするまでメーター読みで1000whほどなのでまずまず👌
