Hey guys, this is probly most easily sorted however im really new to all this so just thought id ask for some advice.

I ran my rc car first time last nite for about 15 min or so with a 4000mah Lipo with full charge.

However not long after, my V on the transmitter screen dropped to 9.3 from something like 10,5v and it continuously wont stop beeping, which im guessing is some sort of low voltage alarm?

Anyone give me a lil insight on this? Thankyou.
