I've used thes in several projects
Why I chose this BMS PCB was because of the layout. This unit just so happens to be almost the same size as the step up PS I wanted to use. When Soldered together they both fit into a single 18650 battery case! Perfectly! See pics. Its like it was made to do this. NO modding required, AT ALL, its amazing, really made my project alot simpler. Anyway this doesn't have a battery balancer so U better make sure when u 1st use these the batteries have just come out of the charger. The batteries I chose for this project are Samsung 18650's that have protection circuits themselves which I highly recommend or U may have some immediate problems or down the road problems, ya know while ur sleeping and a battery explodes and burns ur house down. USE CAUTION for goodness sakes.

One worked one didnt
I had to order 2 more of these because the first two I ordered awahile back, one worked great and one didn't work at all. So Ive ordered 2 more.. since these are Soo cheap I didn't try to dispute or return the defective one. The one that did work, worked great and made my project completely successful.. but the second one frizzed out when I plugged it in for the first time. I just wish I had tested it before I installed it into my project which I had to completely rip back apart because this one didn't work. 3 stars because one worked well. 5 stars of you wanted to replace the broken one. But it's not that big of a deal.

ArduinoをUSB typeCから昇圧して稼働させるように注文しました。 モジュールのみなのでとりあえず繋げてみてテストしてみましたが、問題なく動作は確認できました。 小さいですがケースに組み込むにはなかなか難しいので3Dプリンターなどで専用のケースを作成することができるなら色々な使い方ができて便利だと思います。

あくまでもバッテリーチャージャであって、バッテリーの放電制御までは付いていません。 充電制御用のチップはCN3302で割と目にするものです。Li-IONバッテリーは2セル対応でMax8.4V。 とはいえ、2セルの中間点での管理はしていないので、1セルのみ不良や、2つのセルの性能に 差がある(実容量に大きな差があるとか)とうまく充電できない可能性高いです。 USBから5V供給すると、開放端で約8.7V、バッテリー満充電で約8.1V出力されます。 (これはバッテリーからの出力と思います。) また、このボードの電源にUSB-PD電源は使えませんでした。よって、8.4Vで2Aおよそ17W の出力との仕様ですがこれも現実的ではありません。PDではなく通常の5VUSB電源からしか電源取れ ないのですが、いわゆる普通のUSB電源で5V4A近い出力のある電源は見たことがありません。 出力はせいぜい0.5~1A以内かと。充電速度もあまり期待できないと思います。 充電制御しかできないため、バッテリ駆動のために別の仕組みが必要なのは大きなマイナスと 感じます。(充放電制御可能な類似ボードもかなり安価に入手できます。) 充電器としての機能については確認テストの結果大きな問題ないので、星は3にとどめました。 (気持ち的には星2・・・この手のボードにしては高価でコスパ悪すぎです。)
