My boat recomand 30c. Could i use 25? Rapicon lipo good choice?

[waterproof]

Hello.

I have a kyosho boat with 80 amp esc from orion and 2080kv outrunner aqua motor.
The box says 3-4s lipo 3000-5000mh but in the manual it stands part number to Orion batteries with 3-4s 4000mh 35C.
I wonder how low amp battery i could use in this boat? What is the difference to the boat if it gets lower C and how can i calculate witch battery i could use or not?

Anyone have experiance with Rapicon lipo? Good quality or not?

Today i use a billow 4s with 40c 2250mh and it very hot after use.

Many thanks for advice

40C is a better cell than a 25C,
How many minutes did you run the boat for with the billow 4s 40c 2250mah pack ?
Also what was hot in the boat,
Motor, esc, cells, What were the temp with a temp probe ?

Would a 25c 4400mh be warmer or colder with this setup vs the 40c 2200mh?

Who is most powerfull between 40c 2250mh vs 25c 4400mh?

In theory,

40CX2250mah=90amp output
25CX4400mah=110amp output

You would also have more runtime with the 4400mah.

Hello and thanks for answers :)

Yes i see, the 2250mh 40c will give 90amp, its stand on the battery with a note: 90amp max cont and 180amp max burst, what do they mean?

I wrote wrong on the topic tread because on the Box is just stand 3-4s 4000 lipo, but in the manual they have listet up Orion battery with part number that i need this to run the boat because it came without battery.
The Orion battery in the manual is 3-4s 4000 35C. Do it mean that i need 35c battery? example 4000mh x 35C=140Amp battery. Do i need minimum 140 amp on this boat?

Could i continue to use this billowy battery? And how can i find out whats the minimum amp the boat need to not get damaged?

The billowy 90Amp cont/180amp max burst that i own been real hot after use, i havent tools to take temprature yet, but its only the battery that is hot, the motor is outrunner and a bit hot but that is normal, esc and motor cable is room temperature, i would say its cold, battery connection also cold. Only the battery running hot.

I hope someone could explane this to me :) I have also ordered a 4400mh 25c=110A, dont know if i should Return it and order another battery or not.

I have take temp With a tempgun and the esc is 86f/30c and the battery was 149.90f/65.5c and its been 140f/60c after 2 minutes.
The billowy battery says it must be disconnected and cooled if it exeded 158f/70c.
What do you guys think? Could i continue to use this battery to the boat and will the new one with 4s 4400mh 25c =110Amps be a lot cooler?

[oscarel]

By billowy do you mean puffed? If it's getting hot then I think you've answered your own question. What boat exactly is this? Is it all stock including the prop?
If the manufacturer stated 3-4s 4000mh 35C, why would you go smaller?

Billowy is the make of lipo.

Yes billowy is the manufacture.
No one in my country have big enough battery with high C rate because this boat have small space so not many 3000-4000mh 4s will fit.
The boat is all stock with stock prop.
Its the kyosho jetstream 888 ve with 2080kv outrunner motor and 80A esc from orion.
