Greetings,
I present a question purely about safety. Is it safe to charge an 18650 with a low-current/constant-voltage setup as below? I have posed various questions to Google and everything seems to point to the "right" way to charge batteries. In short, is it safe to use an LDO or other constant voltage device to charge an 18650 to 4.2v?
Solar = 1W 6V
LDO = LM2596 set at 4.2v output
18650 = 9800mah lithium ion
All signs seem to point to yes. The maximum 0.02C charge rate is low enough to satisfy all stages of "safe" lithium ion charging. And, assuming the battery voltage is never discharged below 3.2v, could a device be powered directly from the battery at the same time?
Thanks for any help. The attached picture show the setup with every piece except the melted solder. Is the diode even needed?
