As per Felix the 748RS had a YTX7 battery as standars but also had a connector for a slave battery. Dallas has recently junked the large lead acid battery on his race 996SPS and fitted a RS type battery tray and a YTX7 battery. I spoke to him yesterday and he said he had been having problems trying to get it started which he cured yesterday by fitting a new battery. What I don't know if this was a new YTX7 battery or a bigger one. I will try an find out later when he switches his phone on |
