Thank you for the reply. That reminded me that the Li-Pos in RC cars can be overcharged and explode. I have another question. The battery has 7 amps, 20ah. Does that mean it lasts for 20 hours? I feel like it wouldn't always be the same because a more powerful device drawing more current would discharge it faster. Does it always take 20 hours to run out of charge? The battery will only run for a maximum of 30 min in total per day and it will be charging the rest of the time.
Thanks
