Battery and ESC Match

[Gilbert Pun]

Hi

I am planning to put 2 sets 4000Mah 30C connecting in series to make a 10S battery.

Normally I am using a 180A ESC on 6S with no major problems.

Can 130HV ESC or 180A handle this 10 S battery?

Appreciate for any ideas.

Depends on the voltage rating of you ESC. What ESC do you want to use? What hull and motor?

I am using it on a Deltaforce 67 hull with a 5692 1000kv motor.

Can the 130amp HV ESC handle the 10S battery?

HV ESC's can usually take 10S but the only way to know for sure is to read the specss on the ESC. Which ESC is it?

We cannot help you if you will not give us more details - what is the exact ESC you want to use? If the "HV ESC" is rated to at least 10S then that is one of the parameters needed to answer your question. The other is the use you plan for the boat. For much sport use where you will not be trying for maximum speed a 135 amp controller may work....but all you'd need to do is prop up one size too much and BAM! no more ESC. A 180 amp minimum is a safer choice....if the rating is valid. Many cheap controllers may say they are good for 180 amps, but a lot of them will not actually stand that amp draw for long. Propped and run sensibly a decent quality 180 amp controller would be fine. I placed third at a 2013 R/C Boat World Championship event racing the Open Cat class with a Schulze 40-160 on 10S averaging about 140 amps for each of five heats. You do not have to pull crazy amps on 10S to go fast.

Yes it will handle 10S1P that you have indicated BUT, will it handle the current you are going to try and pull from your batteries??

A DF 67 is a 41" to 42" hull and since you are only running 1P it is a fairly light setup.

What brand of Batteries are you running because even thought they are 30C you max amp pull from them since they are only 4000Mah is 4AH x 30C = 120 amps. So, your esc can handle 120 amps but, if you prop too large you risk damaging your cells or worse they could light up inside if you over prop your boat. What props do you have?

If you are thinking of a 180 amp HV esc, you are most likely talking about a YGE 180HV or the Hobby King Knock off version 180 amp HV ESC ...... This ESC has no water cooling and programming could be a bear if you don't know them well. Water cooling tubes could be added if you have the skills but, thats alot of work when for a little more you could have a SF240.

If it was me, I would suggest the Swordfish 240 for safe headroom but, again your cells could be in danger if you over prop it.

Yes, on the first few trial I was using SEAKING 180AR marine ESC on 6S, now change to using a SEAKing 130HV, on a DF67 42", pushing a 455 prop, this time hooking with 2 ACE 4000 Mah 5S1P 30 C batteries in series to make a 10s.

Well, I don't know if your batteries will cut it as i have never used that brand. They are rather low on the "C" rating for that rpm range.

You are going to be turning a 55mm prop at 37,000 rpm in a mono... If it were me I would run 2P or a smaller prop to start but, I've only run 6S and no higher voltage. That motor is more for 8S than 10S and a 55mm prop.

Just my .02 worth.

i wouldnt risk it , i would go straight to a castle creations 240amp HV

I love the smell of a burnt ESC in the Morning. Did he say 10S on a 1000kv motor? with a 455. thats 70 mph. on a 130amp controller. No way. a 180 would not cut it.

The last couple of runs on this Deltaforce 67 was recorded on a GPS at 90.6kph, the set up is 8S1P, pushing a 5694 1000Kv motor, through a 130a HV ESC, the propeller is 455.
