Don't know if this is a battery issue but here goes....
35" DF Pirate mono with 2200kv Nue motor, Seaking 180 esc running 4s single pack at first then 2 2s packs in series. Prop is a 1814/3 or a x447. So the boat runs really great for like 2 laps and then the LVC kicks in. So i lowered the cut off in the esc from 3.4 to 3.2. It ran for about 3 laps then same thing....voltage cut off kicks in. So again i moved the cut off in the esc down to 2.8v(which i don't like) and the boat ran better and maybe 4 laps but the LVC kicked in again. So i got a parallel cable done and ran 2 4s packs in parallel. This time it ran to maybe 4-5 laps and then boom LVC kicked in!!! Oh the packs are 5000mah on the 4s and 6000mah on the 2s. Now the reason this is frustrating is i know i can't complete a 6 lap race(7 if you include the start mill) with it doing this. And i really don't want to turn the cut off in the esc to off.
My twin cat runs 2 2075kv SSS motors with the same 180a seaking esc's and i can run it on 4s or 6s all day pulling a 1716/2-45-19 or 1816/2-45-17 props all day and that doesn't happen. I don't fully understand the whole amp/current draw, but the temps on the mono are between 115 on the batteries and motor to 128/130 on the esc. While on my cat it never get hot hardly.
Help!!!
