What is ur fav batt for brushed tiny whoop

Hi all, may you share your favourite batt, with some pros/cons maybe any link to buy.

My own fav is 250mAh lipo, pros : cheap, easy to get/buy, and light enough for 6mm-7mm motor.

I dont like hv version because the cycle life time.

Extra note :
But i like hv compatibility ver, because it lightweight but hard to find local store that sell lipo with that size.

I have used GNB, BetaFPV and RaceDayQuads and the RDQ batts are the best of the three, then GNB and somewhere below that is the betas
