A Pack of LiPo cells are about £60-80 though, so buying more unfortunately wouldnt prove justifiable (2 packs of cells is almost a new charger).
I get where your coming from though. I have even looked to buy another Pulsar 3 as the assumption would be they are alot cheaper now given the touch is out, but alas they are not (still go for about £140-150) then plus the parrellel balancer (about £20).
I will keep my eye out for a deal on an LRP, till then I will have to just be savey charging my cells up
cheers
