Can you also charge a 7.4V battery with this?

Hello.
I have a question about [DFR0208].
[DFR0208] has three LEDs.
I would like to know what the three LEDs mean.
In particular, I would like to know the Error LED.
Thanks for reading.
JaneYu Hey Scott,
Sorry for the confusion.The 500mA charging rate is just giving one example of how you could charge a battery. The maximum current can be manually set up to 1000mA. Therefore, you can choose the current you would like to supply. Check out the datasheet linked to get a full understanding of what you could do!
JaneYu Ok....but if you can charge it at up to 1000mA, that means you can use any value <1000...it's only confusing to state that 500mA is the answer. The more important point is that "mA per hour" doesn't make any sense, and I can't even imagine how to correct the typo. Just trying to help.
Can I charge 3.7 battery using this and 9V solar panel (https://www.dfrobot.com/pro...
JaneYu You can't use the solar module directly, since the charging port is the usb port, you can add a energy harvester https://www.dfrobot.com/pro... for the solar panel
When I charge the battery alone - without any circuit connected to it -- the battery is charged as expected.
When the circuit is connected ( current consumption of circuit is less than 5 mA ). The battery does not charge.
Any suggestions how to get around this problem?
JaneYu Could you attach some pictures about how you do with the wiring, and the wiring when it is not charged.
I have the DFR0208 board - it is not charging the battery (LiNixMnyCozO2). Pin2 voltage always remains below 0.2v irresepective of battery voltage ( itested for 0.5 1.75 and 3.5V values)
I assume this meansthat charger is always in precharge state? How can make it switch to constant charge mode?
JaneYu Yes, it stays red all of the time. The battery will show completely charged in my other DFRobot chargers. How do I go about getting a replacement?
JaneYu Please email: [email protected] about the detail of replacement
I ordered 3 chargers. My battery never shows the green light for fully charged on one of the chargers. I have tried 3 different batteries. All of the batteries show fully charged on the other 2 chargers. Is there anything I should try?
JaneYu i have a question i plugged this charger in a USB charger and the green LED is solid light and the Red LED is blinking. so i plugged in my 3.7v 1000maH battery and nothing happens the Green LED is solid and the red is blinking. is there something wrong?
JaneYu
