I'd recommend a starter. You only have approximately 23% viability there. Looking at the BS yeast tool, it is calling for 2 vials at that viability with a .85mL starter, so I would say maybe a step up starter would be called for. That is based on an OG of 1.048. There are several threads regarding this on here.
