battery charging

I have several 18650 Li-Ion batteries, many with different capacities. Can I charge them with the same charging circuit (5 to 3.7 V 1 A buck converter)? Can I put them in parallel and use the same step up circuit to make a 5 V USB bank?

2 identical batteries in parallel, but unequal discharge?

So, I''m not sure what''s going on here... I built up 2 separate batteries, each one with brand new 3.2v 280 amp hour lifepo4 prismatic cells, 4s configuration, using an overkill BMS on each. Then the two batteries are in parallel to the positive and negative bus. Everything seems great except...

Can I Mix Different Batteries in Parallel? (Different Voltage Batteries …

When two batteries of different amp-hour (Ah) ratings are connected in parallel using diodes, the battery with the higher Ah rating will charge the other battery. The amount of charge that flows from the high Ah battery to the low Ah battery is determined by the difference in their Ah ratings and the efficiency of the diode.

Connection of two batteries with different charging/discharging currents …

You may connect two batteries: The first has a charging/discharging current limit of 20 A and the second 10 A. Procedure: The DC terminals A and B must be switched parallely using the jumpers provided. The battery limited to a …

How to Solve Complicated Circuits with Kirchhoff''s Current Law …

Step 4) Using the equations you''ve created (only the one in this case), put together the equations for the current into and out of each node. So, at N 1 we know that we have I 1 and I 2 going in and I 3 going out. Again, we''re assuming all of this (and it''s a very reasonable assumption in this case) and if our assumptions are wrong, the way that will …
