Does anyone know where's best to get a compatible 12V for the 2013-2016 Model S that took the DCS-33UNC RIT 30Ah? I've been looking around and I'm struggling to find a reasonable match in the UK.

It seems that no-one has an answer for this yet, so I've ordered something that seems to match and will let people know if it works! There are various suppliers offering similar batteries, I did go for a cheaper one since I had no idea whether the system would accept it. Since it's basically just a slightly fancy lead acid battery (the main thing seemed to be to go with an AGM - glass matting battery), this should work, but I may regret going cheap.

His analysis is that the charge cycle is really tough on batteries and that it's better to go for an increased capacity. There seems to be space for a slightly larger battery and some suppliers offer units that look like they might fit, I just wasn't brave enough to try.
