Batboard

Hi there,

I recently acquired a complete Astro Saber AVA off of E-bay. It was advertised as Kit# NTN7227E, however when I finally got home from travel and opened the package I discovered that it's actually kit # NTN7227A. Can anyone tell me the differences in the A verses E. Also, will the "A" version safely charge Nickel-Metal Hydride battery's ? I understand that the firmware is different in the E version. Any help

thanks

Dan..
