Hey there guys, I currently run a Speed Passion GT2.0 Pro in both my 2WD & 4WD off road buggies (1/10th).

I run an 8.5T in the 2WD & a 6.5T in the 4WD.

I have this:



Specification:
Capacity: 1880uf (4*470uf)
Voltage: 16V.
Impedance: 0.002 ohm
Ripple Current Endurance: 24 Amp
Size: 42mm x 17mm x 11mm

Super low impedance.
Low temperature in working state.
Reduces the RF interference to make the RC model more reliable,
Improves the burst power when the motor starts to run.
With its excellent "Ripple Current Endurance", the interference caused by the quick switch on/off of the MOSFET can be observably reduced.


I want to use this:



Specification:
Capacity: 660uf (330uF*2).
Voltage: 16V.
Impedance: 0.002 ohm
Ripple Current Endurance: 24 Amp
Size: 30mm(L) * 13mm(W) * 13mm(H).

I may have answered my own question - the 4 cap unit has three times the capacity of the 2 cap unit. 1880uf vs. 660uf. But if this is the case how does the Orion and the new Hobbywing 3.0 make such good use of these 2 cap units but the older GT2.0 Pro cannot - or is it that the 4 unit cap just has a lot more capacity built into it and possibly more than it actually needs - over spec'd?

What it comes down to is this - can I use the smaller 2 cap unit in my B5?!

I can live with the 4 cap unit in my 4WD. Although I'd like to swap it out as well.

Can someone help me out with an answer?

Thanks in advance.

I've seen no difference between a 4cap and a 2cap on a Hobbywing v3.1 in a mod car running a 5.0 motor with turbo. Both felt the same.

You'll be fine running a 2cap on a 2wd buggy even with an 8.5 motor.

You may want to ask this in the electric off road section. There is a Speed Passion thread there and someone in the know might be able to help you out,
