SLF question,
On long flights I often plug in my laptop as the battery is not good for more than say 5 hours tops. If the charging of Li-ion batteries is a significant risk factor, why am I allowed to plug in my laptop in flight? Surely a discharging battery is safer than one that is floating? Has the attidude to Li-ion batteries in flight thus been a bit too commercial driven (reduce weight / make us SLF happy) than safety driven?
