has/does anyone ever use/used the mamba max pro? I have a dumb ? ......it says it can use up to 6s lipo, now a 3 s lipo is rated at 11.1 volts ( I know they charge up higher to start with), so 6 s is 22.2 volts, but then they say only 6-12 cells NimH you would think you could use at least 14 cells, my 7 cells charge up to 10.71 volts so two of them would only give you ~ 20 volts??? so why couldn't you go up to 14 cells NimH? has anyonr possed this question before?
