M4 Stock tube lipo

[col.redneck]

Hope I'm posting this in the right place.

I'm working on a project M4, and I want to use the Magpul PTS CTR stock.
I hate having anything hanging off my aeg other than a holosight, so an external battery is out of the question. I found an 11.1v 1100mah lipo that
fits the stock tube.

I have experience with lipo batteries and know that if you discharge them beyond a certain point the battery is good for the garbage. Normally I'd use
a low voltage indicator that has a small beeper alarm that sounds when it's time to swap out the battery. The problem is that this wont fit in the stock
tube (at least the ones I know).

Anyone have a fix for this?

Thanks.

The beeper is too wide (35mm) for the tube. Im hoping someone here knows where to get smaller ones.

Have a look here: hobbycity.com

They have similar units but for $4.75, I have a few here but I can't find them, go to the site and check the sizing for yourself.

I have a 11.1v lipo in my buffer tube. What brand is yours? Hot power? Mine is very tight in the lipo with the CTR. My lipo is about 1cm left hanging out of the buffertube.

Haven't done the mod yet. I wont do it without the low voltage alarm.
Too much risk to burn the battery.

Tips for your hotpower battery. Before you charge, connect the balancer first(withou connecting the charger ), the balancer can auto detect and recover the battery if needed. When you connect the balancer, the LED light may turn on blue ,meaning it is detecting and balancing the battery. When the LED blue light turns off, you can charge with the balancer now.

So the balancer LED has to turn blue, and if it's off, it needs to charge?
What if one day the LED doesn't turn on? Should I charge?
Oh, okay I understand now. Also the red light turns to blue on the charger which means it's done charging right?
