A quality battery pack made from authentic name-brand 18650-format cells should last for over 1000 charge and dis-charge cycles. If you drain your battery pack once a week, then your pack should last over 3 years. However, you might be able to more than double the battery packs life by charging it at a lower (slower) charge rate (3A instead of the faster 5A or 7A), and also if you only charge the pack to 80% of its maximum voltage.

You won't be losing 20% of your potential range, you might lose only 5% of possible range, but...that is well worth making the expensive battery pack last over twice as long. (6 years instead of 3 years?).

We didn't take an existing charger and slap the Luna name on it. We special-ordered a quality charger from a respected manufacturer, and specified certain features that we feel are the most important. It has a difgital voltage read-out (why don't they all have that?), a choice between a slow charge at 3A, or a fast charge at 5A. Most importantly, we made sure to include an 80%/90%/100% three-way switch so you can choose max possible range, or max possible life. Other chargers give you only two choices...take it or leave it.
