I use for led lights (actually want to use for my arduino electronic projects) So if my battery falls to 8.5V, then do I need to charge it to 12.4 V ? Any suggestion on controller - a lower Amp controller?

Sorry, I am new to this batteries, controllers , panels. SO please can you explain more. My main concern is ..am I going to damage my battery etc. I want to know the basic setup rule. Batter is connected to Controller . SO assuming that controller is the core. what is the relation between...

I have 2 different solar panels 10W/18V maximum power current = 0.55A . short circuit 0.61A using 8A charge controller 30W short circuit - 1.70A , open circuit voltage - 22.9V , using controller - 40A charge controller I used car batteries till now, but want to use different batteries -...

Thanks for the reply. My setup is very small. a small panel. and controller gives me alligator clips to connect to battery. I will get SAE to O ring

I am struggling to understand what components to use to consume power from battery. From solar panel controller, I get alligator clips to be connected to battery. Now how to consume battery power? In the picture, if I use terminal connector with cap on battery, and o-ring to consume power for...

Sorry, I have 3 or 4 batteries and want to make a battery pack. Goal - I want to produce 12v from my batteries for IoT.

Is this ok? Please note my components are 10W solar panel with 8A charge controller. load charge= 8A max, cut-out - 14.2V, Cut in - 13V...

yes. I want to reuse my batteries to harvest solar energy for my IoT

Hi, I bought a panel and an 8A controller , see image I want to make a rechargeable battery pack using existing lithium polymer batteries - 3840mah , 3.7V Please suggest what module/ board to be used in between the charge controller and the battery. Also suggest best practices to have long...
