i got some battery's, what should i do with them ??
i got a some lithium ion battery's, the good stuff,18650 Samsung 2600 mAh I've tested them they are the real deal. about 300 of them are connected together in 3 series so that gives me about 100 battery packs. i have another 200 or so that are just loose battery's, not connected together and they don't have any bms. So how would you fit them into my system. i live in a rv so i have a 12 volt system but i really only use that for lighting the 12 volt rv system has a charger that works but the 12 volt batterys are almost dead. i have a grid tie inverter system, i produce around 5 to 7 kwh per day. one point that i would like to make is that i've been reading a lot about lithium ion batterys and evidence is beginning to show that charging the battery to full capacity is not good for the batterys in the long run, i would like to charge the batterys to 80 percent and then use the batterys to 50 percent, i cant find a charger that will do that with a 3s battery pack system. i also have a 1000 watt 12 volt inverter that can change 12 volts dc into 110 volt ac. so anyone have advice ? best cheapest way to use these batterys ?
