amazing informative video 🔥 for me 💖

[@AmazTech]

Thorough & Insightful. What are those GRAY w/ RedBlue connectors called? First small connector is for SERIES? Second is for Parallel?

[@robert0joe]

Thanks for watching! Those are just knock-off WAGO connectors. The second one is parallel yes (splits both blue and red into three), while the first and smaller one is just for connecting two wires for each color (blue to blue, red to red)

Is it only on bq batteries

[@deiminaskutkevicius331]

what is the name of that charging module BMS?

[@robert0joe]

Do you mean the one shown at 5:05? This is the TP4056 Li-ion charger, good for charging Li-ion cells from USB. Comes in USB-C or microUSB versions.

[@tossancuyota7848]

you can fix that dead/bloated/oxidized batterby adding a small amount of sodium sulfite with a little of pure liquid hydrogen

[@robert0joe]

I haven't looked that much into revitalizing dead li-ions, since I know they're not worth the effort. If I really needed cells, I'd rather buy new, or salvage from other battery packs.

[@tossancuyota7848]

@@robert0joe its worth it though a little bit dangerous as u need be careful not to poke the foil inside to avoid igniting the battery
