It can be very easy, you're protected from destroying the battery easily. But you can very easily get many thousands of extra sessions from a battery that's fairly easy to replace and not really all that expensive I think.
Anyway, avoid deep discharges, there are 'reserve sessions' after the 'battery meter' runs off the bottom, avoid they. Avoid them. If you start it up and the meter shows 'no bars, but it still works' end the session and charge. Avoid 'charge while using', do one or the other but not both, tougher on the poor battery actually. In the 'worst case' (dead battery but running anyway while it fights for charge) can kill a battery in not many hours. Don't do that.
When you charge, fill it up. But because maximum charge ages the battery just sitting waiting (which is why new ones come about 2/3 charged......) if you can stop it when the top (7th lamp lights but the charge LED is still flashing you can DOUBLE the lifespan. Double. Another technique that's more fun and easier is to fully charge (until the flashing stops) then immediately enjoy a session to lower the charge........
Enjoy your Solo, solid choice.
