Darn, I'd definitely be interested in those multimeters of yours, but postage to the UK may just make it cheaper to buy some new cheap meters... Know any way to avoid transatlantic shipping costs? xD

It would cost $13.45 to ship them to the UK.

Wow, just converted that to pounds and that's a great deal! Only about £16 for both meters and shipping! I'll definitely buy them then if they're still available, just send me an email with payment details and whatever.

hey i might buy that li-ion pack if you can tell me how many times its been charged and you can turn it into an 8s4p that can handle at least a 10-15c continuous discharge without melting. ill also take a charger if you've got one :D.

P.S. is there any way i can pay without a credit card

I'm not sure how many times it's been charged. However 18650's can only provide a continuous discharge at about 1.3A per cell. It's a different chemistry than li-po. Li-ion has a higher internal resistance. I'm not sure of any li-ion cell that can discharge at more than 2c.

I've drawn a continuous current of about 6 amps from it. The only reason I'm selling it is because I exploded my charger...

I could accept a money order.

I'm not so sure about that. I've never seen a li-ion with a greater discharge rate than 2c.

Sorry I couldn't help.

check out these li-ions

Link2

li-ions are commonly used in ev's instead of li-po because they dont explode as easy.
