    Question about Lithium cells

    Thanks for the heads-up, this would come in handy!

    Question about Lithium cells

    Haha It most certainly did ... Poof = Not good. Referring back to one of your previous suggestion of connecting a few TP4056 in parallel to charge 3S cells. Mind telling me if that'd go Poof? I think this would round up most of the curiosity

    Oh... Thought it would cause a short just as a TP4056 would... If the grounds aren't isolated. Thought I'd be the same with the TP5100

    Question about Lithium cells

    Thanks, this confirms my understanding so far. Now to put it into to practice... Hope this doesn't blow up! Got some insight to connecting a few of those tp5100 connected in parallel and whether it would short or not?

    🤣 Then it beats the overall purpose of the mod. Portability + universal charging. I do have an old PS, that was being replaced at a highschool. None the less good suggestion 😂

    Question about Lithium cells

    Oh dang, you said parallel... I was thinking in series. Brain freeze. Yup TP5100 can provide up to 2A. So 4 of those puppies in parallel would give 8A. For 3S, that's 2.6A per cell ... right at the max rated charging current for these cells. If I parallel connect the 4 x TP5100 from the same...

    Close enough after I'm done with this mod 😂

    Question about Lithium cells

    It's a belkin adapter, with one particular USB port able to deliver the total rated 50W given that no other port is used. To get the 50W delivery from the adapter, I'd have to use a power delivery decoy module to trigger the 50W. Didn't know 3 tp4056 would allow the current to increase...

    Ok that's good then

    Question about Lithium cells

    Please elaborate on x3 charging. From what I know (so far) : If charging 3p... It'd still be charged at a constant voltage of 4.2V. The varying factor would be the current. So if I'd want to charge each cell in the 3p at 2.5A, I'd need to supply 4.2V, 7.5A (charger receiver module capable of 5V...

    Question about Lithium cells

    But I assume with a lower voltage, a higher (compensated) current can damage the motor...?

    Agreed. Hence I appreciate all the input from the members in my preliminary inquiries before I put it into practice.

    Question about Lithium cells

    I had a feeling about that. Also I've been searching for a higher Watt isolator (8 to 10W) for another project, but haven't come across one so far (except for only 5W). That doesn't sound healthy for the that 1p Learning something new (guess now I've a couple of spares). I thought if the...

    Question about Lithium cells

    I guess if I set it in 3p... Then I'd have a higher capacity, and then step/boost it up to the desired voltage. I guess I'll still have a higher capacity compared to just only 2 cells in series?

    Question about Lithium cells

    No, definitely not going to use it beyond it's design limits. Just educating myself/curiosity. What if the battery is charged just 300 or 400mA more than it is rated? Would that be as dangerous/bad as the scenario I mentioned earlier? Goofy is the least, can't even find a configuration label...
