Lipo with vintage speedo

[RichH]

For reasons I'll not explain I need a new battery. It's only for bashing but was thinking of trying lipo. I have an old brushed set up but i have a new receiver with a fail safe. I've heard you can't fully discharge lipo, will the failsafe do? Will it work with an old set up and is it worth it? I have a multi charger so that's not an issue.

Cheers
