Batteries...which to get?!?

[njc11]

Bit of advice, please...

Im going to have to get a some sets of batteries ( i will build up myself ) as i have realised all the sets i have (bought a job lot when getting back into RC Racing) will not be legal for BRCA Nationals.. they will be fine for regionals and club racing which is fine, but need to get some new ones..ohh im also planning on doing Worksop this year 2008/2009..

Which ones should i get!!? theres quite a few to choose from on the BRCA site.. (im using a pro-trak charger)

Any help would be much appreciated!

Cheers

Nick
