<arossdotme-planb> this 20Ah usb power bank is stupidly cheep, i guess they have been sitting around and now they are selling them off http://www.mymemory.co.uk/Portable-Power/Dianlang/Dianlang-Gigantic-20%2C000-mAh-Dual-Portable-Power-Bank
<arossdotme-planb> im trying to work out if it multiple cells or one huge cell? as if its multiple, i would like to reconfigure it into a high voltage battery. like 14.8v pack ideally :D

<whitequark> 18650 cells inside
<whitequark> very very shitty 18650 cells, not worth the money
<whitequark> even the little money it costs
<whitequark> looks like six 18650 cells

<arossdotme-planb> whitequark, how did you find out?
<arossdotme-planb> btw mymemory are a err popular company here in the uk
<arossdotme-planb> thanks muchly also
<whitequark> because all those powerbanks use 18650 cells...
<whitequark> the dimensions fit, too

<arossdotme-planb> oh
<arossdotme-planb> thx
<arossdotme-planb> how shitty will they be?
<arossdotme-planb> i expect that they have aged. i think i remember it costing a lot more a year ago...
<arossdotme-planb> shitty as in they will kill me or as in they cant output many amps?
<arossdotme-planb> 3amps?
<whitequark> shitty as in they're like 1/5 of the stated capacity
<whitequark> li-ion got really cheap lately due to whatever economic effect it is
<whitequark> but that is still *too* cheap
<whitequark> look up panasonic 18650be, those are good cells
<arossdotme-planb> ok, thanks again, love ya :)

<whitequark> arossdotme-planb: i have no doubt you'll find some place, 18650s are incredibly common
<whitequark> amazon: 1-16 of 27,264 results for "18650"
<arossdotme-planb> yea, ending up looking on amazon, but most of them are for small quantity’s. there are results like this http://www.amazon.co.uk/dp/B0180T7O6U/ref=twister_dp_update?_encoding=UTF8&psc=1 and other sellers have multiable options for buying 1-10 with didiscountor multi-buy
<arossdotme-planb> ps. £40 for 8. is that a good deal or fake crap? when it looks like its £60 for 10.

<arossdotme-planb> I assume that its best that i buy a pack of batts so there hopfully from the same batch
<whitequark> £40 for 8 sounds about right £40 for 8
<whitequark> er
<whitequark> these are with integrated protection too
<arossdotme-planb> so then this site is over priced then http://www.ebatterys.co.uk/panasonic-18650-battery-cell-c-47296.html
<arossdotme-planb> hmm
<arossdotme-planb> guess from your link that they dont need to say Panasonic then, ok
<arossdotme-planb> any cautions about laptop/drill packs?
<arossdotme-planb> i guess i dont know what mah cells they have
<arossdotme-planb> read something about laptop batt pack manufactors getting all the latest best batts
