Sick of having to fork out for expensive MBP batteries? Is it possible to make one from an old exploded battery pack and some 18650 cells..?
MBPs have a huge discharge rate, so any MBP left unused for a few months will result is a dead battery, ad the MBP will actually flip a kill switch in the BMS. It is possible, however, to reverse this, and revive the battery, so long as none of the LiPo cells have not blown.

I got hold of four secondhand Sony VTC5 batteries in Talat Din Daeng for 500 baht, from the same bloke who sold me the dodgy Wismec (see Wismec RX200), with a pretty purple (yet blown) 4GB Kingston USB DT101 G2 thrown in (see Stick it up your USB).
After the initial excitement, it started to sink in that they were probably fakes. When will I ever learn?

XTAR… Due to my unfortunate experience with the awful charging functionality of a Wismec RX200 vaper, I was looking into getting a upgrade to my agéd yet venerable XTAR VC2 (which was able to resurrect a dead LiPo, see Reviving a dead 18650 LiPo) and I was perusing the XTAR Official Store on AliExpress. Now, while the newer products are all really rather good, there seem to be some inconsistencies between the XTAR product range and the naming.

I had my first 18650 LiPo death recently. A single battery left in a Target Pro mod, for over six months. The mod would not charge the 18650 at all… that is to say that the charging light would show the animation of the battery charging, but no process was ever made in the state of the charge (over the space of 12 hours).

Following on from GhettoVaper – an extended GhettoVape III, I thought that I would add, if possible, the ability to balance charge the LIPos via a micro USB port. However, as the battery configuration is 2P, and not 2S, it may not be possible.
This time we are looking at PCB chargers, and Battery Management Systems (BMS).
LiFePo4 batteries are safer to use than LiPo, but there are some drawbacks. They are often used in RC for transmitters. This blog was initially part of RC Transmitters – Turnigy 9XR Pro, but has become its own separate article. Continue reading LiFePo4 Batteries
I saw a Fusion Breeze Plus LX40 for sale cheap on eBay, under the nondescript title of li po battery charger, £1.79 + £3.95. This is a very cheap charger, that can not balance or discharge or be calibrated, and can only charge up to 4S batteries. Continue reading Fusion Breeze Plus LX40

Following on from Service please!, after watching a few more RC tutorials, I realised that I was severely lacking in knowledge on the power side of things.
