AiLi Battery monitor

[Plowboy]

Hello! I am a newbi here and my knowledge is not 0 but defiantly a novias. I have a Aili 500 ah battery monitor, I believe I have it installed correctly as all functions seem to work well EXCEPT the %. It will be reading 100% when fully charged, count down to 99.9% and then immediately drop to 0%. Do I have a faulty devise or have I done something wrong with installation or programing? This is on a 105AH Deep cycle battery in a small RV. Please help if you can

I have the same monitor. Did you calibrate it for 100%? There is a procedure in the manual. You charge the battery fully, then you do the procedure to "tell" the monitor that "Hey, this is 100%."

You need to set the battery AH size. Sounds like yours is set for something real low.

If I recall, out of the box, the default is set to 100Ah. But that setting needs to be double checked too.

Thank you all for the response, I have reset it per the owners manual! Seems to be working correctly now. Thanks!
