I found some 5Ah 18650s on ebay for less t ha £1. Wow I thought. A bit of digging on "Hi capacity power products" reveals that they print 5000mAh on the cells but they deliver just 1000mAh and the price is the expected £1/Ah/cell. Bit surprised to see such blatant lies from a 'big' supplier.
Anyway, regardless, started looking at how to stack these things & came up with using a 100mm diameter 'soil pipe' with 19P cells inside - stack as many s as you want (11s is 40V and ~750mm long). Just wondered if anyone else had used this system already - it would appear to be quite attractive
