Hi Good day. I am planning to work on a power circuit for my arduino. I waant to create a simple solar rover, and since rovers move outside, there is no power outlet. Solar panels will do the job for charging. I was planning to use LiPo batteries and according to my research, LiPo batteries can explode and start a fire when overcharged, I don't want my rover to be in flames within the first few hours of its journey.
Now my question is what can I do or is there an IC board for this issue. I've heard of mppt charge controllers but I am not sure if they cut out the charging circuit from the panels when its fully charge. Can mppt sense when the LiPo is full charge? If it can, can it cut out the power from the solar panels then wait until the battery is low then charge it again? Basically can it plug and unplug the power when the battery needs it? Looking forward to you answer... Thank you.
These work great for all of the projects I have done. All you need to do is hook up your battery. There is also a resistor that you can change to alter the charging current, just look at the table in the data sheet.
Hi, thanks for your reply. So this board has an overcharge protection, so it can automatically stop the charging once the LiPo is full right? What is the maximum charging voltage of this board? Do I need a buck converter in case it is more than the specified voltage?
Yes, (if you get the ones I sent), you supply the board with five volts through either wires or usb and the board will charge the battery with 4.2 volts (perfect if you have a 3.7 volt battery). No you will not need a buck converter as the board does it. If you look at the graph in its data sheet, the board will stop charging the battery once it gets fully charged (led indicator will switch).
Though you will be fine with overcharge, be careful with over discharge. The board will stop the battery at around 2.5v, and though it is fine, don’t let it get under it. Also, you might have to change the charging current. What is the capacity of the battery (ex. 100maH, 1700 maH, etc), or better yet: what is the maximum charging current for the batteyr stated by the manufacturer?
I have not chosen a battery yet, but from what I am seeing in my online shopping site, the 3.7v LiPo only offers to about 600Mah. What I like about these LiPos is that they are more compact than Li-ions, however the compact ones tend to be the less capacity one hehe. I am not sure if the turnigy 7.2v 2200mah will be safe for the board since the charging voltage is 4.2 I guess.
ONLY USE THE TP4056 FOR ONE CELL BATTERIES. The 600 mah one will work fine with the chartering board as long as the current is appropriate, but do not use multiple cell batteries with it
It won't work anyways. I researched on it it was 3s, so its a no for that. However I would like to ask, for this kind of battery what mppt should I use?
