When I check to battery it said 6.6volts after than I do not think the red ESC have a LVC or it is not activated.
Both the stock Jpowers and HK's ESC in the 50mm series DO HAVE LVC .... and it is set-up as factory default ..... like nearly every other ESC on the market ........
What has probably happened with other guys T45 is the voltage on his small pack dipped below LVC due to the load while flying ... it cuts out ...
Small packs in these are a dead dog in my opinion ... except the F16 etc. of course where it's difficult to fit a decent sized pack.
