Have you tried to run it till the light cuts out automactically? There was another customer over at MTB forum who also had his red light came on sooner with the new pack. He was advice to ignore the red light. I sort of question that advice because the original design of the light head was suppose to be design such that the red indicator is a warning telling us that the battery is going to shutoff soon. If the new pack design cannot match the original intended design of the light head, then that warning light is good for nothing.

So far, I'm not impressed with new pack either. The case is very nice. The battery or PCB is iffy. I got a new 900 light set last week with the GMG battery. I plugged in charger. Green light showed right away. I tried battery on the light and nada. Took an old light and still nada on new battery. Took new light on old battery and light head is OK. Tried the new charger on old battery and charger is OK. Battery came DOA! Send pack back to Geoman under warranty. Should be getting back one this or early next week. ARGH!!!!
