Tell us about yourself!
Please explain. What does it 'protect' against? Does it stop charging when 1 or more cells are at 4.2 volts?
Did you check to see how well the BMS module balanced the batteries during charging and discharging? Does thte BMS you show stop charging when the cells are fully charged? I bought a couple of different ones on eBay, but haven't gotten around to see how they work. My plan is to replace by NiCad batteries with LiIon in my power tools.
Have you experimented with high gluten flour vs. regular? I prefer high gluten for bread, but it may not be right for buns.
Everything looks perfect, except you left out one step. After mixing in the pasta, bake uncovered in a casserole dish for 30 minutes at 350.
Nice tool. Being a breadmaker, I have the same problem. It's very difficult to find a blade that is sharp enough to cut and not pull.
Electrical work should be left to professionals.
