These are the batteries from Aventon pace 500 and 350 bikes. There is nothing wrong with the light. The green light just shows when its on. To check the power level you just push the button. You hold the button to turn it off. But I don't know why they have been rejected.

I think you are right. At switching on, the LEDs indicate that they are working, regardless on the battery state as long as it is not completely empty. The display on the handle bar will show the actual state during your cycling tour. When disconnected from the bike you can request the battery state by switching it on, the press the button for a short time so it does not switch off and the LEDs will roughly indicate the 1/4, 2/4, 3/4 or 4/4 state for a view seconds. So nothing wrong with them, just an obsolete or redundant batch of batteries sold for scrap.

All of them are dead and this is what I often find with packs that have been left. Seems to be the "mystery of batteries" I have stripped one of the f0 batteries and found they are 2200ma Samsung cells so they should be good quality. Found using the IMAX charger that its a 10S2P configuration and that 2 parallel cells are open circuit and the rest all have like 0.2V but do charge up one at a time showing a good capacity when charging. Still have yet to see if they hold a charge but just wonder what caused it to both go open circuit and then all the other cells to almost fully discharge. You think it will come back?
