Sf200, leopard 4082 on 4s2p issues

[millzee]

I ran my new 4082 in my mean machine today and it was running sweet for about 2.20minutes but then it was like the LVC kicked in, I bought the boat in and checked and the batteries where still at 15.4volt. While swapping batteries, I checked the programming on the sf200 and the LVC is set to 4s, I reprogrammed it all just incase, plugged it all up and threw it out again. This run was no different from the first, running well for the first 2minutes or so and then started cutting out like the LVC was kicking in, I bought it back in again and the batteries said almost the same as the first set, 15.3volt. For both these runs I was using the internal bec, could this have somthing to do with it or what else should I be looking at????

What packs? They may not have been able to keep up with the draw and the voltage was sagging under load.

there nano techs, 45-90c 5000mah ran 2p. I don't think the batteries where my problem, I just don't know what is?

The LVC on the SF esc cuts of at 15v for 5s, could it be defaulting back to auto and guessing wrong, or and I've done this with the little card thing, had a dip switch set wrong, I switched to a USB programmer as I found the dip switch card too small and a real PITA. It stays in the tool box for emergency use as I bring a laptop to the pond now.
20 years ago I never dreamed I'd need a computer to run boats! USB charger monitoring, esc programming, data loggers........

I'll reprogram it again and maybe drop the internal bec and run a n rx pack. This esc ran fine last time I ran the boat but I was running a 1515, I do remember now that I ran an rx pack then so I guess that'll be my next step, if that doesn't work I guess I throw a t180 back in. My usb programmer is fried so I'll think about getting another if the sf200 starts doing what it should.

I had a problem with the lvc kicking in too soon because my strut was too low
