RE: lithium batteries
Absolutely nothing. However, I had a vague notion that with so much use of lithium s, of various types, in jet models it might just be of some interest and provide useful information from a highly credible source, however slight, to those users in possibly preventing a lithium "incident".
I for one, thought that lithium manganese (such as Duralite sell) was less hazardous than lithium polymer, but one of mine recently "ballooned" for no obvious reason.
This sort of comment is why I really don't bother much with RCU these days.
