Returning to RC Lipo advice

[Rob]

Haven't raced for 7 years due to having kids, still got my B4 which going to carry on with initially and brushless esc/motor etc.

But I'm going to need new batteries, I see it's all lipo now, seems to be so much choice. Can anyone recommend decent value lipo battery for club racing. I take it you need just 2 packs?

Also will need a new lipo charger, again what should I go for that isn't too expensive but not cheap rubbish?
