Oh most definitely , Its so much easier to just swap cells out than using built-in lipos theres down time whilst re-charching,
It also depends on capacity of lipos , i use all types , as long as you set the cut off of lipo right there pretty good not a much of drop off as much as the 18650s , its just an inbuilt cells not much different than triple 18650s , unless using in Pwn an such then can go crazy high wattage with high amps output too,
imkind of looking forward to the newer cells , dual 20650s LG,s an such higher capacity and amps for just 2mm wider than 18650s there looking very promising
