DAOKAI 5 Pcs 1/2/3/4/5/6/7/8S Lithium Battery Capacity Indicator Module 3.7V Green Battery Capacity LED Display Board for DIY with 26AWG Wire

Neat unit, you select the number of cells by a solder blob across labelled pads.Only works for the specified chemistry of lithium battery.Power for the LEDs is taken down the same cable as the voltage sense, so keep the cable short and use low-voltage-drop connectors to avoid errors.

On the info it says S1 = 1battery S3 = 3 Batteries ?SO I have 5 in a row (AA 6.0V 800mAh Rechargeable) although 5 x 1.5 +7.5 volts and when i check on a volt meter i get 7.5 volts ? BUT when S5 is connected at rear of unit it shows red only to charge.When i connect S2 it shows 2-3 blue bars (and 7.2volts on meter) all other connection just show red (to charge) now see pic from a web site ?SO how can it show all 5 bars to show 100% full ...it can't ???

I have used the battery tester in 7S mode after soldering the pads marked S7 together, I ran power up on my Bench PSU and the red light came on at about 4V then the green lights started to come on at about 24V to about 29V when it showed full.I tested my battery pack and it was at 29V, when I connected the battery tester it flashed and then failed. I tested 3 more from the pack and each one failed either when disconnected from the bench PSU or when attached to the battery pack.I have checked the instructions online and I think I am doing everything right but they keep on failing.

All have failed after a few minutes. This is particularly annoying when you check it works then put into a case and it fails. I think it is a diode that burns out

Tried bridging the 1S, 2S, and 4S individually and no LED's come on when plugged into a fully charged 4.8V battery.

Mann sieht sofort wie viel Prozent der akku noch hat. Für denn Einbau muss man nur löten können.

Tutto ok

Je l'ai utilisé dans un haut-parleur amplifié avec un module Blutooth. je l'ai alimenté avec trois batterie Lipo en série. Elle sont protégées par un BMS 3S. Un chargeur Lipo "step-up" assure la recharge à partir d'une alimentation externe 5V. J'ai vérifié les palier d'allumage des LED au voltmètre: 11.9V, 11.2V, 10.4V et 9.8V. Le fonctionnement de l'indicateur est correct.Mais je n'avais pas fait attention à le dimension. Je m'attendais en fait à la taille d'un boitier type DIL16. Par manque de place j'ai dû décaler l'interrupteur d'alim sur la gauche. Du coup les potentiomètres du correcteur de tonalité sont un peu trop rapprochés. Lorsque les boutons sont sur les axes les textes "Aigus" et "Basses" ne sont pas lisibles .. .

Funciona perfeito .
