Is it possible to put the 5v regulated outputs of two separate lipo rider pros in series with one another making a 10v battery effectively?
alternatively, is it possible to put both of the separate outputs in parallel effectively doubling the supply current. In this scenario, i would also need to step the voltage up to 7v for an arduino mega which i believe to be possible with a mc3063 chip.
What implications would each of these scenarios have on the battery health?
The preferred method, if it would be possible to separate the grounds, would be to use the supply outputs in series to increase the voltage (in series) instead of limiting the supply current with a voltage step up circuit. (if they were in parallel)
I actually tested putting them both in series and it did not read as 10v but just 5v. My guess as to why is probably due to there being a common ground between the two charging circuits that causes a short.
Seems to be effectively ignoring one battery if put in series.
I have looked around and there is nothing in line of an adjustable or customizable solar lipo charger. They are all very rigidly based on 5v in and 5v out and only support 1 celled lipos. I suppose I could utilize just a single charger and put both of the batteries in parallel making 3.7v (6000mAh+6000mAh = 12000mAh)
The benefit to continuing to use one lipo charger per battery would be the independence of charging. ie each battery will be slightly different and be used slightly differently and as such each battery should benefit by being charged independently, no?
You can put the outputs in series and since they are independent enough it should provide 10V indeed. However, connecting them together either in series or in parallel is not recommended. By combining the outputs you might changes the characteristics of eh circuit and cause a behaviours that is difficult to predict.
The best approach if finding a charger that matches or exceeds your power needs and then regulate the output accordingly.
