I have been reading this forum for quite some time and have finally got round to starting a conversion. I'm hoping to start a build thread but for now I have a couple of questions on batteries.
I can get hold of some Boston Power Swing 4400 lithium cells (http://liionbms.com/pdf/bostonpower/swing4400.pdf
) at what seems like a decent price. They are not brand new so I'm a bit wary but I haven't got a huge budget so my lithium options are limited. They apparently came out of a prototype electric van when the company developing them went bust.
Does anyone have any experience or advice on this cells? There seems to be nobody using them and I don't know if there is a good reason for that!
Is there anything that I can do if I go and have a look at them to test what kind of state they are in or whether there are any bad cells?
