mini review of the Hitachi electric lithium ion screwdriver....i love this thing ! it made assembling my tlr22 and d8t rc cars a breeze, i forget to mention it has spindle lock so even if you run out of battery you can still use it as a manual screwdriver
the battery packs uses samsung 18650 li-ion batteries, should you wear out the battery you could possibly put any 18650 battery in there (there is a temp probe but its seems to be separate circuit, as of the video you can get 2.6Ah 18650 batteries)
