Wheelbarrows are such a pain in that they need you to put in all the effort.
My aim with this project is to produce the best budget electric wheelbarrow that costs less than £200 ($275). I use second hand Lithium ion cells from old discarded laptop batteries as my power source and a second hand wheelchair motor to power it all with.
In this episode we are all about how to make a 24v Lithium ion battery pack (arguably the most expensive part of the whole build). I leave no part of it out and I lay bare my 'limited' knowledge on how to do this. How does it turn out? Well stick around and see............
Apologies for the number of times I say "Basically!" throughout the whole video!
