I have a 4pk and I'm using a life battery and my battery settings are right but when I use it for a while it just shuts off automatically with out the low voltage alarm coming on its so annoying it always happen during a race any advice would help a lot

Whats the voltage show just before it shuts off ?

That's just how it it's with the life battery. I get about 30 seconds once the low battery alert goes. I heard of anyone who's been able to change the alert threshold. I try to recharge around 6.4V
