    Hi guys,

    I've been flying my Cinestar HL with a 8kg payload (Red dragon, MOVI, lens and pull focus) over the last couple of months and get about 5 minutes flight time using a 16,000mah Tattu battery.

    I've done some calculations and it just seems very low....

    I typically fly down to 22V (3.7V per cell) using the telemetry on my Futaba 14SG however when I put the battery back on charge (using a CellPro PL8) it seems that I'm only using 60% of the battery capacity. I could possibly using another 15% quite safely.

    What are your thoughts?

    I would like to try using 2 x 10,000mah batteries in parallel or maybe even 2 x 12,000mah. This would give some redundancy considering the cost of the equipment I'm flying.

    Do you guys fly based on the voltage you see in your telemetry or do you know basically what voltage corresponds with 80% usage of your battery?

    Looking forward to hearing from you all!
