I'm charging the stock battery using the stock charger - lipo system from Mirage. I plug the charger in and the lights go green. Plug the battery into it and the lights alternate between green and red. The manual says they should turn red, no mention of what flashing lights mean. This is a stock 3s lipo with the charger that has 3 LEDs. First charge - everything is brand new.

I just noticed the charger makes a high pitch sound when plugged in (no battery attached). Not sure if that is meaningful, but thought I'd mention it. Lights are green without a battery on it. No other lipos or chargers, so I have no way to troubleshoot.

Scrap the stock charger. Use it for a jump rope.
Get an ac680 thunder charger. It like 55$ it does EVERYTHING and super easy to use.
I would assume the green to red flashing means its charging. Its probably one that charges by the balancing lead? So when the light go green it should be good.

I checked those out and have one on the way. I guess I will see how good Redcat support is. Not sure if I need a new battery or charger though.

I would think u need a new batt.
As lomg as u never draind it all the way down.

This is all brand new, and this was the first charge. I put on meter on the battery and it has 11.49 volts.

So u got the ac680, and it.only went to 11.5v?
Theres a timer on it, I think its set for an hour. Take it up to 120mins. Thats what I did, it works great.

Not yet, the AC680 is on the way. 11.49 is what the battery is out of the box new.

Oh ok
