Anyone got any recommendations for a good(ish) battery optimiser that won't cost the earth? If possible I'd like to get one of the ones that come with a permanent mount so I don't have to keep taking my seat off.
Most of the ones I can find are about £60, though there are a few in the £40 range.
Do they get any less than that? I finish at work here in 2 weeks time, so am trying to save pennies wherever possible!
