Hi, I bought an AVATAR RS200W yesterday and i'd like to explain if this is a normal issue on the lipo batt: - It was on 12% charge when i left it on my bag, dully protected. After 2 hours without ussing it, when i fired it the battery charge was at 46%. Then after 5 puffs went down to 36%. Is that normal? how can it go up and down so quick? Another question is: on escribe, ont he mod section, should i clik on maximixe charging or maximize puffs? thanks in advance
