  Yup, just plugged it in there. The internal resistance of these cells was high enough that it limited the current somewhere between 3-8A. And this was done only briefly as these cells got quite…warm.

  I remember recovering dead 18650 cells from laptop batteries and “restoring” them with a 12V modded PC PSU. Quite a few of them actually started working again and had some capacity for a few tens of additional cycles. Those cells were never left unattended in a charger and they were always only used in a device you could chuck in a moment’s notice.

  10/10 do not recommend.

  Considering that even the hybrid cars made by car manufacturers themselves are heavier than their ICE counterparts, I don’t think that by retrofitting an older car you’ll get a better result.

  For example, 2024 Hyundai Tucson curb weights:

  Heaviest ICE: 3663 lbs

  Lightest hybrid: 3692 lbs

  Lightest plugin hybrid: 4115 lbs

  The biggest issue with an EV conversion is the weight of the batteries. For a lot of passenger cars, adding 500kg of batteries maxes out or even exceeds the vehicle’s gross weight.

  I’d tell you one, but it got stuck on the event horizon of yo momma

  Logitech m330 with a single AA Ni-MH battery. Have been using the same battery for the last 4 months, wondering when will it die.

  I also have a smart charger for the batteries, so I can just keep them in there without the risk of damaging the batteries. The moment the battery dies, I’ll just take another one and swap it quicker than it would take me to find a usb-c charger.
