Easy remove disposable vape cell with contacts
Added 2024-03-21 19:44:22 +0000 UTCThis is a very pleasing twist on the disposable vaping devices. It's a new style of the Blu device that has a very easy to remove lithium cell in a rugged capacitor style package with a concentric gold contact PCB on the end.
The case and contact system would make a very handy format for small lithium cells in general.

I connect the socket side to the battery, so the pins can't easily get short circuited. The charger will supply limited current, but shorting the lithium cell will result in very high current.

2024-03-27 01:35:47 +0000 UTCThanks Big Clive. I'm curious if there is a sort of standard as to which end of these plugs you'd connect to a battery vs a supplied power source? Probably a stupid question but I look at a socket on perhaps a Laptop vs the plug that supplies power and that seems pretty straight forward but like the JST connectors, I never know which to connect to the power source vs the load.

2024-03-26 22:33:43 +0000 UTCI've found all disposable vape type lithium cells are very variable in their capacity vs what they state they are. Some that are 550 mAh can be as low as Clive has found with this capacitor looking LiPo cell. I have had more success with the larger vape LiPo cells, the 1000 mAh and better still the 1500 mAh cells from the much larger disposable Vapes. I have made up 3S battery packs using matched capacity 550 mAh Vape LiPos, but each battery pack I have made using 3S BMAs have resulted in one cell always loosing capacity after only 2 or 3 cycles. The 3S packs have also been made using different BMA pcbs, so it’s not common to BMAs, it’s just inferior cheap disposable LiPo battery packs just not being up to being reused.
