Hi everyone,
I am using FED3 for long-term experiments (longer than a week), so I am thinking to switch the batteries of FED from original 4400mAh ones to 6600mAh ones (https://www.adafruit.com/product/353), so that we could minimize the frequency to change batteries. But I'm not sure if this battery is compatible with FED (I'm new to Arduino devices), and whether some code/scripts need to be changed when switching to this battery with higher capacity. Does someone have some idea on that?
Best,
Sunny

Hi Yuhui.
The battery is compatible, although it will take longer to charge.
Cheers.

Hi Sunny, the bigger battery is compatible but the bottom cover will not close with that 6600mAh battery. You will likely need to edit the 3D design to fit it.
But we often run multi-week experiments with FED3. We keep extra batteries charged with these little LiPo chargers and just swap a fresh battery in after ~7 days while we're topping up the pellets. Will that work for you?

Does anyone have a version of the 3D design modified so that it can accept the 6600mAh battery pack?

Hi,
I didn’t modify the FED housing to fit the 6600mAh battery, but I want to share my setup now for keeping the FEDs powered. I’m following Lex’s suggestions and it works fine so far. I have a backup battery for each FED. And I bought six Lipo chargers (make sure to solder it to make the charging faster at a 0.5A speed, rather than 0.1A) and a USB wall charger that have six USB ports (maximum 2.4A for each port and 12A total for all the ports; see attached photo for its look). This way I can charge six batteries at the same time and it takes ~10 hours to get fully charged. You can buy more Lipo chargers and the USB wall chargers to speed it up if needed.
Best,
Sunny

Hi!I was wondering why are you changing the batteries at all. we also run experiments with FEDs lasting more than a month, but we recharge all the units simultaneously while they are running and we have never had a problem with batteries.
Best.

Hi Hamid,
Thanks for your advice! I put FEDs directly in the home cages when running them, so I guess it is kind of impossible to charge them while they’re running without switching batteries and without keeping the cage lid open. I use FEDs in BSL2 facility so I think we have to keep the lid close at all times if not in a biosafety cabinet
Best,
Sunny

this setup is similar to us, we use this charger which looks good,
