Edit: Not looking to make money, just cover costs. Cheap used Li-Ion cells, please read.

I read these forums occasionally but have rarely contributed. I am selling something here so please move this if its breaking the rules, I hope people are interested enough to keep it here though.

I work for a power tool manufacturer here in the UK. We recently had a batch of 10.8V batteries with a PCB that allowed 1 out of 3 the cells to fail, balancing issues.

Now we have 300+ good cells that we cannot refurbish into saleable products for the power tool market but which make excellent RC batteries.

These cells quite happily put out 10 Amps for 6-10 mins on a charge.

I have 2x Losi MLST2 cars running brushless with Mamba 25 ESCs. I run them on 2 cells each and get around 15 mins of bashing per charge.

Cells are marked as:
ATL.WTK IRN18650 3.6V 1300mAh B49908401083
Each cell weighs around 40g, 65x12mm

Each pack is wired in 3 cells 10.8V 1300mAh, 12V when charged, with a pcb to balance and protect cells.

I can sell these as a bulk lot (expect around 30% failed cells, pcb may or may not be functional) or can break them up into good cells and sell individually.

Open to offers, just don't want them to go to waste.
Very reasonable postage to UK mainland.
If there is interest I will stick these on ebay.

If anyone has an idea of how to best use these cells please reply. I would hate to see them wasted.
