ECO-WORTHY 12V 100AH LiFePO4 Lithium Battery with Bluetooth, Max.1280Wh Energy, Low Temperature Protection, Group 24, Built-in 100A BMS, Perfect for Trolling Motor, RV, Boat, Solar Off-Grid

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!

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.

Ao far they have been good, no issues.

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.

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.

丁度いい

車内で100V電源を使いたくて走行充電器とインバーターと一緒に購入。 通常使用だと電源容量も問題無く快適に使用出来る。 夏場ポータブルクーラーに使用すると放電しきってしまうので、追加購入を検討中。 値段も安く良い商品だと思います。

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👌

日本語説明がないことが少し残念。
