Smart Battery Led Light Issue

[Hezarfen]

I noticed it at night. The LEDs of one of my smart batteries are very dim. Does this mean the battery is faulty?
The LEDs of my other batteries are normally off, but one of these battery LEDs is lighting very low.

Your battery is not faulty, this is a common occurrence with the Solo batteries. I can't recall exactly now, but it was assumed this was related to the self discharge feature of the BMS. Not that the LED is the load for the discharge, just a by-product of the circuit from the BMS.

The topic was discussed way back when it was discovered, search the forum for that topic and discussion if you want more theories as to why this occurs.
