Lipo power on stock Impulse 26 configuration

Hi Guys,

For some reason my Impulse 26 won't run on anything larger than a 7.2v battery. I've tried 8.4v and it just won't power up. I
was thinking about going with a lipo and low voltage cutoff to reduce weight and increase performance. I'm new to the lipo
thing so I was looking for some advice on what size battery to use.

Thanks !

Honestly, if your looking for more performance your going to be disappointed with anything short of upgrading to a brushless setup. That being said if you just wan an try a lipo on stock set up I'm betting you could fit a 5000mah 2s in there.
