Hello! Probably it's a n00b question but I couldn't find much about LiPos parallel charging using diodes.
I am designing a charging station for 6 LiPo 3s batteries.
There are plenty of parallel charging boards in the market but it's common knowledge that if the voltage difference between the batteries is too big, the current flowing between them will damage them. In my application, the batteries will never have the same level because are used by different people in different times.
So I was thinking to a sequential charger controlled by a micro-controller that charges the battery one by one. However, this seems a bit of overkilling to me and I am thinking about a fully hardware solution. Could I just parallel charge the LiPos adding a Schottky on every line connecting the cells? It should prevent current flowing between the batteries. What are the drawbacks of this solution? the voltage drop across the diode?
Thank you in advance!
