Seems like you're on the right track here... Most general purpose small signal transistors can deliver around 100mA and they only need 0,7V to open the CE...
Now, I haven't practiced this theory since school 20-25 years back, so it's only form memory my suggestion...
Same here I did electronics engineering 25 years ago and didnt even use any of it till I got an ebike.
The simulation proggy helps a lot.
I wanted something that had low volts and current on the base and the simulation transistor seemed to started switching on at .7 and full on properly between 1.8v and 2v just like the spec sheet says.
I saw one circuit with darlington pairs trigger from the current off you fingers. EG touch sensitive.. I got a grip on the math for the transistors but I need to familiarise myself with how it works or else I am wasting my time.
If you were to ask me ohms law, LOL I couldnt tell you, I have to look at each calculation I am making and make it up. The Law helps you to understand how the processes of the math works in the science. But if the penny doesnt drop, attempting to apply the math is a trivial pursuit. If I wasnt to understand how it works I woukldnt even know what Law goes where.
Its 2am here and I am getting tired. More of this latter,
Thanks for the suggestions. I am determined to make this proper
Sooner or later I would have to deal with the transistor formula again. I was trying to avoid it.
I am waiting to get the bills together for a Magic Pie and just building things while I wait.
I will be looking at building a
BMS for some cells I have comming and using that 1 amp transformers ive been playing with..
Again I was going to use the LM338 almost identical to the LM317t but 5a rateing for each cell but this is overkill compared to some small transistors. But the current and voltage regulation on a cell would be spot on.
I had a simulation
BMS built just using resistors and its fine at 1 amp. Something about using 10% of your charge for balancing.
Last but not least I have some LM2576 simple switchers ICs good for 60v I am itching to put right up at the rectifier. And on a solar panel charger I am working on.
The four panels in series reads over 80v and can output 80 watts at 68v and I plan to use 18 lifepo4 cells on the trailer jump battery. 59.4v cold and 64.4v hot. And for my main bike pack I want 16 cells.
The solar jump pack will be a 1.2 amp charger to the other pack. This will allow the current always travel down hill to my bike pack.
Anyway thanks again.
Good night all. I needs some sleep.
