I know this maybe a popular question. But what is the proper way to leave a battery when not used. I have been told that when I am done running my slash that I should recharge the battery and let it sit. But why do alot of chargers say that they discharge batterys? Is that what you are supposed to do? I have a reedy 3400 Nimh battery. and looking to eventually move to lipo, but like to know how to properly maintain my batterys first. I have an onyx 230 charger is it a good one?
