I would like to make a 30W (1A) led panel battery powered. I have a boost converter, 5-35V and 2A max, laying around I'd like to use with a 2S 2200mAh LiPo in order to reach ~1.5 hours of continuous usage.
What do you suggest to use in order to prevent overdischarging the battery? Are there batteries with a cut-off circuit?
