Hi! Thank you for your opinion - it is much appreciated! Please allow us to explain our position. We use Lithium Polymer (LiPo) batteries in all of our devices because they are incredibly safe. Lithium Polymer batteries have flexible packaging with aluminum that protects from any kind of explosion or hazardous situation - especially considering users are not constantly handling them. Further, Lithium Polymer batteries must be soldered into the device which also prevents them from being user replaceable.
Conversely, devices with user replaceable batteries, use hard-shelled lithium Ion (Li-ion 18650) batteries that are not designed to stay permanently in place. The act of taking 18650s in and out of devices or chargers can damage the cell's insulating wrapper, compromising the safety of the battery. Users could also replace these batteries with inferior/defective batteries, or mishandle these batteries, potentially causing these types of devices to become unsafe.
We understand that this is controversial and we will not argue these points. As a company and manufacturer, we have simply chosen the safety of Lithium Polymer (LiPo) batteries for your protection and ours. Additionally, our insurance company would not cover our devices if they had replaceable Lithium Ion (Li-ion) batteries.
Please also note that all of our devices carry a one year free replacement warranty and a lifetime 1/2 price replacement warranty that includes battery degradation or manufacturer defect. *Please visit our website for the entire warranty information.
Thank you all for your support!
