Fuim3 diy


Hey guys,

While I respect buying the original parts out of supporting the vendor's R&D, I found myself having forgotten to order an FUIM3 cable and wanting only to make sure I had the latest firmware.

As I had however seen how a poster had hooked up a bluetooth module, since I had an FTDI programmer handy (FT232 chipset, called "FTDI friend" by the folks at Adafruit), I managed to get going without needing the cable. Attaching a picture but essentially, it calls for connecting the same layout as the bluetooth module hookup with the same switching diode (1n4148) along with a 10k and 100 ohm resistors. I set the FTDI adapter to 115200 in the windows device manager and also plugged together the FTDI VCC 5v out to the PL8 VCC pin.

When I had originally tried it, I had not connected the 5V and this was resulting in a less pleasant corruption of the firmware during upgrade
So I plugged in the 5V and also switched the baud rate to 115200 in the windows driver as specified above and that seemed to work although I am not sure which change managed to fix it.

So really, purely for those electronics guys with an FTDI programmer and diodes lying around that somehow didnt have a FUIM3 programmer on hand. I really dont care much for programming the charger myself and havent seen much point in it thus far (and didnt feel like waiting for a cable to be delivered).

Hi Guys - does the pl8 autodetect 6v, 12v, or 24v sla batteries?

No - and I want to know how to do this properly. It's been explained before but I don't quite understand it. Preset templates didn't have any 6v 12v or 24v I could see.

Library Preset 25 (12v SLA or Gel Cell)
Under the Detection tab: the Cells selection lists:
Auto Detect and 1 Cell Only through 12 Cells Only.

Is that what you were looking for?

That's what I ended up doing. had to use the computer to change it to autodetect the cell count. I just removed 12v from the preset name.

That will charge at 7A and CV at 13.98V, and terminate at 1/10th of the 7A. Or sooner.

Which means your battery will be way, way undercharged!

You need:
14.1V (2.35vpc) gel
14.4 to 14.6V for generic AGM
14.7V for pure lead like Odyssey/Optima
You need a manual termination setting of 750th to 1000th C where C is capacity to fully charge and return all the lead sulfate back to the gel/acid or suffer a very short service life.

So terminate a 70Ah lead brick at around 100mA or lower preferably 70mA. And set a CV time limit of 8 hours, and a charge limit of 16 hours. You will find it takes a long time to properly charge and saturate a lead battery.

Thanks for this - I'll do this this week!

Sounds really complicated!

How do I charge this pack with my DPL8? There is no default preset I see for it and most the info in the thread relates to ones without a balance lead. I have a JR lead and a balance tap.

The JR lead becomes your main charge/discharge cable. Connect it via an adapter (JR to bullets/bananas) to the banana jacks on your charger. connect the balance tap to the balance connector on your charger via an adapter board. Charge as any 2S battery.

I was gonna say - be careful charging 1c through those servo lead type wires. My heli has a 6000mah 2s lipo and I tried to charge at 1c and the servo connectors melted and the wires got really hot! Luckily I caught it... so now I only charge it at max 2.5amp!

Not really, but if you don't do this your expensive lead brick field batteries will die much, much sooner! Stock pre-set is not even close to optimal.

I searched through this thread searching for subject matter on Android tablets. I purchased one last year for my work and now it has mostly replaced my laptop. I have a mini USB adaptor and can mount most large USB and other devices to it.

I was wonder if anyone is working on a program to run a Power Lab 8 ( the CCS software) for a Android tablet. I looked through the Google Play Store and did find some software for the bump charger but nothing for the power labs or any other charger.
