The main issue is that the one downside is that lithium batteries can easily catch fire if mistreated, and they cannot be put out (which is why most RC hobbyists keep a bucket of sand on their workbench). If you're not super familiar with lithium cells it is easy to make a small mistake that could start a big fire. Please just save your money for a bit longer and buy an off-the-shelf unit.
