[B]This what I have:
24V47A Plug-n-Play Supply
These will provide 24V at up to 47A, and are basically two of the 47A (above) supplies wired in series. They require a PC power cord for you to connect your charger. When you plug them in, they just come on. These work well with the Hyperion Super Duo or FMA PowerLab chargers. These are sold pre-wired with your choice of connector. Note the option for both 12/24V.
$110 24V with 4mm bullet connectors
DUAL CORD: $8 for each unit and MUST be ordered with a power supply (can change in Paypal to multiple cords if necessary). The item consists of 3 parts: Two 1ft 16ga power cords and one 14" 14ga Y adaptor.
I bought this last year and used it once. I do not push my batteries beyond 1C so this was overkill for me. I will ship free in the continental US for ***.
