The MPA won't work with the Multi4 because the charger does not have JST-XH wiring mode. While a skilled modeler *could* get it to work, it would only work for a single cell count and the charge current would be limited.

The Powerlab6 and Powerlab8 both use the same JST-PA 9 pin connector. This is a very nice connector with a thumb clip for easy release and close pin spacing so it's very compact. Its about the same width as a JST-XH 6s (7pin) connector but easier to connect and disconnect. The Powerlab6 uses pins 1 through 6 and pin 9 in FMA wiring mode. In JST-XH wiring mode pins 1 through 7 are used.

Power Supply ?


I just received the PL8 and have the Revolectrix 28 AMP power supply. As best I can tell from what I have read, the power supply should work fine. It just doesn't run the PL8 at it's capacity. Am I correct? Tim

Power Supply


Correct.

Also, don't forget to set the current limit to 23 - 25 amps, or thereabouts; i.e., less than the advertised 28 amp limit. Some power supplies do not handle attempts to draw more current (as the PL8 might try to do for a large pack) gracefully; setting the limits protects your supply and will help the PL8 limit charging to comply with the capabilities of your supply.

Hi:

I'm just confirming the above is the correct answer to prior poster's question.

Does anyone know what the efficiency is for the PL8 with my 28 amp revolectrix power supply? Tim

Use this calculator to determine the answer:

Enter your power supply voltage and current and the number of cells in your battery.

Hi:

The efficiency used by the calculators is set conservatively to a fixed 85%. Results will vary based on output current and output voltage. The calculators are provided to give you a rough idea of what you can expect in terms of output current; not really to help you calculate precise charging efficiencies.

Is there a case/cover for the MPA board?. I got mine in a large padded envelope while it gets knocked about in the charging box (old modified tool box).

Hi:

We do sell some really nice canvas bags. This small one might work for you:

Not a bad solution. I mounted velcro on the back of mine and stuck the corresponding piece to the side of my harbor freight case so it doesn't move around when stowed away. The rest of my components (PL6, dell supplies) are also secured with that heavy duty velcro, nothing moves.

MPA & Safety Banana Cables to Main Battery Output Extension Cables


Hi:

I am building EC3 to female Deans Ultra adapters for my MPA with male Deans Ultra main battery output leads. What gauge wire do you suggest?

Along the same lines, what gauge wire do you suggest for an extension for the safety banana cables? I'm also having trouble tracking down sheathed (safety) banana plugs and jacks which accept 12 or so gauge wire, any suggestions?)

I would use 14 AWG wire. If I were not in a hurry to get them, I would order them for ~$1 each: http://www.hobbyking.com/hobbyking/s...3pcs_bag_.html

Depends on length and intended operating current. Assuming that you'll be using it at close to maximum output of your PowerLab, I would use either 10 or 12 AWG.

Tim are there photos of the inside of the bags anywhere? Was considering buying one for my PL6 but would like to see how stuff fits in there first. Seems to be a common trend with carry case manufacturers never to show the inside.

Also any word on when the MPA bare wire will be in stock? Seems like it has been out of stock for a while.

MPA & PL6 fit in REVOLECTRIX PowerLab Carry Case

grimbeaver:

I bought a PL6 and an MPA together with the larger of the 2 Revolectrix charger bags. I found it too small for the MPA. The MPA will fit well in this bag from corner to corner only, not with the PL6 in the bag too. It could be in the bag with the PL6, but the MPA's power wires are pressed hard over at 90 degrees against the MPA's case.

There is a photo from a user who tried to do this with a PL8 some where in the RCG forums. I can't find it now though.
