Cheers for the link but I've looked at the list already...
It's the "Also EFRA label" bit that confuses me
The current batteries don't have an EFRA label on them - do they need one?
I remember the exhaustive threads about LiPo legality mentioning that the hard cases must be glued together (to avoid tampering) & there was some confusion about whether the current Trakpower batteries were glued - thought may be that the EFRA label denoted an approved change in design.
