[Elecraft] Looking for Li-ion battery packs in VK

[Wilson Lamb]

This probably isn't what's wanted, but might appeal to the hard core DIY ham.
My son gets piles of dead laptop batteries from a computer shop.
Most of the 18650 cells are quite good.
He screens for capacity and discards any under 2Ahr capacity.
He made a bulk charger for the individual cells, using cheaper than dirt single cell chargers and cell holders from Ebay.
I think it does 20 at a time, and now has dozens ready to work.
He buys hardware on Ebay that can be used to make up packs of any configuration.
Subsequent charging can be done by wiring a pigtail to connect the same chargers to the cells in the pack.
Obviously this requires some bench work, but once set up it's pretty efficient.

There's plenty of RC model activity in VK.
Airplane packs are available in a wide range of voltage and current capability, as are chargers.
This is likely the best commercial source.
