Where I have found the real problem with lipo's is in trying to find pack sizes to fit in the 1/18th scale cars,especially the Trinity Spyder.The battery tray is only 70mm longx32mm wide,so you really have to search quite hard to find packs to fit in that small an area,and even then,the ones that you do find,tend to be quite low capacity,i.e. around 900-1000mAh,and they're soft packs too.Even using the nimh cells is a swine because of the battery arrangement,which looks like a humppack on steroids,4 cells on the bottom,with 2 cells piggybacked on top.You try buying that configuration off the shelf
. For me,I'm finding that aeroplane Lipo's are about my best bet, but,you don't really have a lot of choice as to the manufacturer,with most of them coming from the far east.
Well,that's my tuppenceworth.
