Which Capacitor to use?
 

Need to install one on a Mamba Max......is the Novak 2700uf a good choice?
Thanks!

Yes the HV one... I have them on all of mine...

I was told by Griffin that the novak one is a 25volt cap and you need 35volt cap that is rated between 2200 to 3300uf.You can get the cap you need from digikey.com

The novak is 25v which is fine for 4s and a little tight for 5s (mine runs ok on 5s) - 35v would give you more headroom but make sure you get a high temp low esr cap

Which one? Novak 5685 1800uf 35v or 5684 2700uf 25v...does the uf make a deffernce?

We no longer use individual caps on our BL controllers. We have switched over exclusively to the TransCap modules. We do offer some of the earlier caps here:

Power Capacitors

We discontinued all single caps from distribution; but, the ones above are still available.

I guess I dont understand the 5684 states that it is a Trans cap?

That P/N is the TransCap module for the 2s-4s HV controllers.

So I go back to my original question,,,,which capacitor?

How many cells are you running?

We are running 4s.....

The 5684 is for 2s to 4s usage.

If you need one,I'll have one at the store tom.
5684 is the cap's I'm using I have 2 extra ones

Thanks....

thread jacking!~!!!!:lol:

hey, say i didnt want to pay $15 for a flipping capacitor, what constitutes as a low ESR?

and close do i need to mount mine?. like...within 3-4 inches?

Look for a cap that has a 105*C temperature rating. eBay usually has pretty decent deals on 330-470uF caps at 25v and 35v with the required 105*C rating. You mount the caps as close to the ESC as you can while not interfering with mounting.

For an the often recommended 35V 1800uf cap, less than 0.041Ohms. Pretty much only leaves Panasonic FM series caps. Though if you paralleled a bunch of smaller caps you would be fine too. Look for 105C ratings, they usually come hand in hand with relatively low ESR.

i got several new 1800uf 35v low ESR 105C caps if anyone wants one, will send for cheap, only have 2-3. I've added one of these on all my MMs, they works great

add two capacitor instead of a single one to a MM will do something?

Like 2x 25V 2700uF Cap to a Mamba Max on 16.5V?

Generally, using two or three smaller caps is better than one large one for heat dissipation (more surface area) and transient response. So, if you want an extra 1000uF, you can use three 330uF instead. Each cap has to be rated for at least 25% higher voltage than you plan to run. For 4s, that's a 25v cap; for 6s, that's a 35v cap; etc
