It’s common issue, 18650 battery…
Which brand do you recommend ? I know Panasonic, Samsung are good. However, they are cell, not purchase directly. Hopefully, let me know Amazon URL is the best.
Thanks.

2500mah 35a 3.7v Are high discharge batteries harmful to machines?
In general, no. Amps are “pulled” by the system (at least for digital/regulated systems like the uConsole), so the amperage rating (e.g. “35a”) is more like a “max speed” rating. Your uConsole will likely never draw more than a few amps, split between both batteries.
That being said, as an electronic cigarette user (who uses a lot of 18650 batteries) I’ve not heard good things about the EFEST brand. I’d recommend checking Mooch315’s recommended list (he’s an electrical engineer who is a trusted reviewer of batteries in the e-cig world).
You probably want to choose:
- A battery from a well reviewed vendor (Samsung, LG, Panasonic, etc.)
- A battery with a high capacity, e.g. 3000-3500mAh, over a battery with a high discharge rating (e.g. 3500mAh at 5A max is going to better for the uConsole than a 2500mAh with a 25A max rating).

Thanks for the great answer. I also use e-cigarettes, so I was wondering if it would be possible to use it because there are many 18650 batteries.
I have had very good luck with battery junction. They have a wide variety of cells. I would recommend using protected cells. I personally use the 3600 MAH with protection.
no protection circuit size : 65mm(H)
protection circuit size : 69.5mm(H)
Are there any problems with the mounting size?
We carefully designed the battery holder to make it more compatible with various 18650 battery sizes: Φ18±0.5mm diameter, 65-69mm length.
(that’s from https://www.clockworkpi.com/uconsole)
I ordered these as they are protected and within the 69mm limit.
