This BANGGOOD circuit deserves 5 stars for the quality of its manufacture. For the use I wanted to make of it, it doesn't fit. I wanted to protect a 12V-5Ah battery from deep discharge. That is to say disconnect LOAD from a battery voltage lower than 12V. But voila, when the disconnection occurs the BANGGOOD circuit still consumes: 36 mA. CONCLUSION: This circuit is valid for a bigger battery ( 30 Ah ) and a consumption on the LOAD output to several hundred mA. which is not my case (10 mA ). So I'll use it for another application.

Ce circuit BANGGOOD mérite 5 étoiles pour la qualité de sa fabrication. Pour l'utilisation que je voulais en faire ça ne correspond pas. Je voulais protéger une batterie 12V_ 5 Ah de la décharge profonde. C'est à dire déconnecter LOAD à partir d'une tension de la batterie inférieur à 12V. Mais voila, quand la déconnexion se produit le circuit BANGGOOD consomme encore: 36 mA. CONCLUSION: Ce circuit est valable pour une batterie plus grosse ( 30 Ah ) et une consommation sur la sortie LOAD à plusieurs centaines de mA. ce qui n'est pas mon cas (10 mA ). Je l'utiliserai donc pour une autre application.
