Things have slowed down this week as I’ve had to go full time to help on a project at work, I’ve two weeks off from Monday though which I’m very much looking forward to!

In the mean time I’m working through a box of laptop batteries I bought on ebay. They’re great to scavenge batteries from for robots and other projects, that box has promise of up to 54 cells too. Good ones can cost £4 each, it’s pot luck what I get but for £30 for the box it’s worth it as even if only half are good that can be a £100s worth!

The ones I’m testing at the minute have been really drained but slowly coming back to life, fingers crossed for a good haul. They usually take over night to test so this is slow going…
