I also didn't want to deal with the 8d weight
Freedom-2500 original from FT in 1996 with remote. Working fine. After charging all night it is floating at 13.4 which I believe is proper?
FYI, the specs show 2 Deka AGM 8AGC2 Batteries are approximately equivalent to 77% ONE 8D battery. Nice to cut the weight of the 8D in half by using 6v batteries.
