Before the current epidemic of disposable vape pens, Poundland used to sell these disposable phone chargers which had a 650mAh #lithiumPolymer battery connected to a DC-DC boost converter. There was no straightforward way for owners to recharge them.
I've been distracted by e-cig battery harvesting, but finally got around to adding a TC4056A module with over-discharge protection to the few I bought back then
They are now just like USB #rechargeable powerbanks

Sadly those spare #batteries we had were too old. So rather than listen to you all night, with your every minute chirps, off to the store I went. And after sone ladder fumbling and swearing you are silent again for a while more.
I’m still not sure why a hardwired device isn’t a good situation for a #rechargeable battery… if it’s good enough for my OG #Nest…

Either the self-discharge on these NiMH cells is *way* worse than it's supposed to be or my charger is fucked or my recorder is fucked. >:[
I'm not sure which possibility I like least.

[Atomic 14] shows how to power #LED #Christmas lights with those free rechargeable Li-poly batteries you can find discarded on the street and along footpaths. Experiments with making them charge wirelesslessly did not turn out as planned.

I am buying my mom some LED candles for #Christmas.
And I want to buy rechargeable batteries for them. I already have this recharger: https://www.amazon.com/Panasonic-K-KJ17MCA4BA-Individual-eneloop-Rechargeable/dp/B00JHKSMJU/ref=sr_1_2_sspa?crid=1AR2N1828AMSX&keywords=eneloop+charger&qid=1670078508&sprefix=endloop+recarger%2Caps%2C63&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRjVRRDBIWDE3MjhEJmVuY3J5cHRlZElkPUEwOTI2ODAzMU5VNEhHWURLWlZQMCZlbmNyeXB0ZWRBZElkPUEwNzU3ODc4M0JFMFpMRTZCS0FZOSZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
Should I buy more Endloop batteries? Or will cheaper ones not explode in this?
Any advice?
