Well , Make sure it has a good charger, one that will balance the cells while charging, and preferably tracks temperatures.
and follow these steps.
Don't charge to 100%, leave the last 5%.
Never let the battery run completely flat, if your bike doesn't have something that tracks the level of every cell, and stops things before any one of the cells hits bottom, you can get a device from the model airplane hobby that will do this.
Don’t charge the battery when it is hot, either from use, or from the sun beating down on it, or below freezing. If it's easy to remove, bring it indoors when you charge it.
If you are someplace where it gets down to -15F or -25C, you have another case where you bring things indoors, depending on what exact chemistry the battery uses, it will freeze around then. It will survive, if you let it thaw at human compatible temperatures, without trying to charge or discharge it until it thaws.
