When people are talking about 'defective' batteries and 'new technology', can we remember that the units installed on the 787 are made up of 8 x LVP65 cells which have been used successfully in various applications for nearly 10 years now.
What is 'new' is the installation and the charging/monitoring system that it is hooked up to as well as the loads it is expected to carry.
I'm sure that the solution to Boeing's problems will lie in the systems hooked up to the batteries, not the batteries themselves.
