But remember, you will need a power supply with 90% of the chargers that are out there.
I bought my power supply right here on RCU from a guy that was selling some HP powersupplies. Had to do some soldering and made my own power distributor from a electronic project box from RadioShack.
Oh, the Accucel 6 in the picture next to my Turnigy 4x6s is also a good charger. I no longer have it because I left it on my rear bumber when I took off for the field so... it's gone
I almost bought another one but I wanted to try out the slick Gens ace charger and I like it a lot.
