Here is a good reference when I said it is best to charge it at lower.
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life.
Some lower-cost consumer chargers
may use the simplified “charge-and-run” method that charges a lithium-ion battery in one hour or less without going to the Stage 2 saturation charge. “Ready” appears when the battery reaches the voltage threshold at Stage 1. Since the state-of-charge (SoC) at this point is only about 85 percent, the user may complain of short runtime, not knowing that the charger is to blame. Many warranty batteries are being replaced for this reason, and this phenomenon is especially common in the cellular industry.
Avoiding full charge has benefits
, and some manufacturers set the charge threshold lower on purpose to prolong battery life.
Well, why didn't you say the info came from the Battery University? I will now change my tactics and charge correctly. I will set my Hitec X4 to Li ion. I think this is the same place I read not to charge my batteries in the plane but that's not going to happen. Good info.
