Quote from: qrper on February 09, 2022, 10:36:17 AMThanks, Bob,I understand the concept of the charge controllers... been using them since '78. I'm still very much old school and prefer to use lead acidâ€"and even the simplest lead acid battery sytemâ€"needs some sort of charge controller.So many of the videos I watched, when the battery (lithium) needs recharged, they simply hook up a power supply and let 'er rip. Other than the BMS, there's no external battery charging controller.I have a Bioenno 1212 battery I use for portable HF work and it's charger is stupid, there's no charge controller for battery control circuits in it. It's a cheap swps. Apparently Bioenno relies on the BMS on the battery to keep it from going up in smoke.We got more snow coming, so I'll park my butt in front of the computer for more videos.mike, wb8vge

These can be either with Relays/Contactors (mostly EV Application) or MOSFET Only usually for lighter duty. Separate Port BMS has a Charge Input Line and a separate Discharge Line each controllable relative to the BMS setup. These are not generally sold to Retail Clients as prebuilt battery packs.
