Hello!
Would someone confirm or refute this one? To charge a battery that small, the user should use the adjustable charger and then set it to use an external bias resistor. However it was the size of the resistor that is bothering me. I believe the issue is in the Learn system for the adjustable charger, but that’s about it. And indeed it is shown there:
Adjustable LiPo Charger Hookup Guide
It looks like 25kOhm to me (for 40mA)…the calculation is from pg 15 in the datasheet
What do you think it should be?
I agree. The cited equation does make sense. But that size isn’t normally carried as a part of the basic resistor kits. I recall I did get it to work the last time I did manage to charge the 40mAH battery from the inventory.
