You may want to consider a battery redundancy system, the Laser is worthy of it. I used two batteries and switches in my Laser just for safety sake/ failure. The other benefit is longer flight time between charges. My set-up uses 1200 mah NiCd batteries for a total mah count of 2400. This is done on all my big planes, I'd hate to lose a plane for a cheap switch or lost battery cell.
