Are these batteries too much weight to put in my Titan? I would use two paralled packs and the total weight would be 1,4Kg = 3 lbs

My present config is:
Motor: Ammo 3650 2300Kv
ESC: Hobbywing Seaking 60A
Prop: Octura X640

2300 kv motor and 5S =42,500 RPM=:flame42:

Thats a 4S motor.

Seems kinda heavy...................two of these in parallel would give you 6000mah at 884 grams.

Here's 7200 mah at 990 grams -

Kinda high on the rpms as i wasnt really looking at your setup, just helping on the batts mainly. Also your ESC wont last long either at only 60a..............can a Seaking 60a take 5s? You'd be a whole lot better on 4s tops.

By reading the specs of the motor and ESC they say 5S is possible.
That's the voltage spec of the Ammo Motor 2300kv 36-50 : Input Voltage: 14.8-18.5V

And that's the voltage spec of the ESC: 1.2 Input: 6-18 cells NiMH/NiCd or 2-6 cells LiPo.

So, I tought I can run 5S on my Titan.
Also I have ordered an X440 prop that is on the way.

Is good to avoid :flashfire: check motor and esc temps after 1 minute run at the beginning than if the temp are OK, 2 minutes and so on?

the weight is fine, talk to Fluid and he actually adds lead...

I am concerned with the size of the motor to weight of boat ratio. Its a good motor, but when you add that much weight to a small AND higher KV motor on high volts, I think you might be stressing the motor, which will then stress the ESC. Temps will definitely be a critical indicator, so be sure to check them as you mentioned at minute intervals. You may be OK with the 40mm prop.

:iagree: with JesseJ, the weight isn't the problem, the voltage is... go with 4s pack for sure... I run two 4s2p 10,000mah in my titan... the extra weight helps hold it on the water.... titans have alot of lift so the weight is a plus actually.... but 5s is def too hot...
