BatteryThere are various ways of storing energy. The one that makes the most sense right now, when it gets to renewable off grid solutions is the lithium iron batteries. <<<<<<< But if you have no dime at all, get an used car or truck battery. If they are to weak to start a car or truck, the mechanics usually throw them away. For sure, you can have still light all night with it. And maybe, you can charge your laptop from it when it is dark and charge it the next day with a solarsystem?. But be aware, that the lead acid? batteries are really poisonous and have to get profesionally recycled after use. |
