Are lithium batteries poorly affected by partial state of charge (PSOC)?

---

No! Drawing current from a lithium battery does not produce any harmful or undesirable byproducts. Charging and recharging simply moves lithium ions from one side of a membrane to another. Lithium batteries also have their peak performance when they spend their life at a partial state of charge. The ideal maximum charge for a lithium-ion battery is about 80-90%. This is much more practical in terms of the time and amperage necessary to recharge your battery, and it gives you a margin of error for when things don’t go as planned.
