Mikey the unit you linked to isn't a redundant supply and you still need to fit a 2s lipo of sufficient capacity in the nose.
Andrew, the A123s at 1100mAh end to end would fit well. Maybe one on top of the other in your application. The bigger 2300mAh size may not. I'm looking at using the 1100s end to end in the Exploders and the Reg max looks good for that application, basically giving 2200mAh and redundancy and dropping the voltage a tad.
I replied to Ken's MRSSA post with this.
The unit described is here.
www.greentronic.eu/en/regmax.htmlCost is AUD $115.00 plus postage.
I have seen discussion somewhere on RCG, where someone's testing has shown an F3X model with all digital servos can momentarily pull 6+ amps. I've never measured it so don't know.
The manual is only in French, so I've Google translated it and edited most (not all) of the resultant weirdness out of it.

The Regmax manual ............
First, thank you for choosing a product in our range, this shows your concern about quality, but also performance.
Product Description
The module comes in a light and compact shape, as optimized for performance gliders, weight and the shape are considered.
It is based on modern technology-based Mosfet power associated with regulation of cutting quality. Radiation, inherent in this technology was minimized by a design study, both in terms of routing printed circuit board as the scheme itself.
The technology of power supplies, allows for a voltage output to exceed the input voltage, this is achieved with excellent performance. In addition, this module includes the input of an electronic DualBat, thus allowing power redundancy and protection against reverse voltage.
Specifications
Maximum input voltage: 5.5V
Recommended input voltage range : 3.3V to 4.5V
Nominal Output Voltage: 5.5 V ± 2%
Continuous output current@3.7V: 3A
Peak output current@3.7V: 4A
Temp. (T ambient = 25 ° C, 3A, Vbat = 3.7V @ 1mn): 35 ° C
Efficiency (Input voltage = 3.7V @ 1A): ≈ 86%
Weight: 18g
Dimensions: 24 x 49 x 7.5
Implementation
Discussion
The applied input lead voltage results in a higher output, Micro Deans connectors are used as standard, combined with very flexible insulated silicone cords. Regarding the output leads their respective pinouts are standard: the red wire is the "plus" it's on the middle pin, the black wire is "minus"..
Source Voltage
In general and in the model application, the source voltage will consist of one or more batteries connected in series.
Various rechargeable battery technologies exist, each with a specific voltage ( NiMh= 1.2V, LiFe V = 3.3). But the batteries used will always be composed of the same technology. For the future, we will talk about battery pack, or the designated source of voltage. The controller is optimized to work with batteries composed a single element or LiPo, LiFe. But it also accepts packs of 3.
Connection
Leads out of the regulator will be connected directly to the receiver (One cord gives sufficient redundancy but power is not total).
Turning on the regulator electronics is done by connecting a battery to each Deans micro connector (can not connect a source of tension, but in this case, there will be no redundancy of power). If both batteries are ok, ie each path is checked, the light turns green. If this is not the case, one battery can provide current but redundant supply is not ensured (See the DualBat module on our site). At power up, rather than connecting each battery one after the other, it is possible to assemble the two micro Deans by a drop of cyano.
Use and precautions for use
Battery Capacity
With this module, the two batteries are "viewed" as being in parallel. As a result, the actual capacity available is the sum of two (they are virtually in parallel). For example: with two packs of 1500 mA capacity actual is 3000 mA ...
Reverse polarity
If you assemble your own battery packs, make sure that the voltage at terminals of the connector micro Deans is with "minus" on the male pin. However, if the regulator was powered in reverse, it would not be damaged, and will protect the electronic components connected downstream.
Short-circuit output
Even if it was necessary to avoid short-circuiting the output of the regulator, this is if not destructive short circuit only lasts a few milliseconds ... Beyond that, the destruction of the regulator to happen sooner or later.
Autonomy
With this regulator, the voltage of embedded electronics in your model remains virtually constant until the end of the battery capacity. Afterwards, the output voltage of the regulator will drop very rapidly, that it will "pump" almost all the energy of the battery to maintain the output voltage to its nominal value. With or without a regulator, the voltage drop at the end of the capacity is very rapid, so always keep a safety margin and do not wait until the last "drop of electricity before recharging your batteries!
Warranty
This product is guaranteed one year in normal conditions of use described high.
