Approx how long would I expect to charge 3x 18650 from cutoff to fully charged, with a 6v 10w panel on a typical sunny day using this solar power manager?
What is the difference between a Type D and a type C
Hi @Robert281517
Assuming the panel is running at max capacity with no loses across the manager board you would be looking at ~4.5 - 5 hours to charge 3 18650s with a capacity of 2600mAh.
The C variant of this board is not one that we currently stock, the biggest difference between it and the D variant is that it is closer to a portable phone charger with USB outputs, and can only accept power via a barrel jack.
