I'm wondering if AudioMoths will accept rechargeable lithium ion batteries and if anyone has tried using them already? I'm curious how long they last compared to NiMH rechargeable or regular lithium ion batteries. Thanks!
I use packs of four 18650 batteries. And work very fine, I can record all the night 1 month without problems. In the test I used a 512 Gb Sd and the audiomoth can record 480 Gb of wav files, and it had remaining energy.
@Alex RogersHello Alex, We use some audiomoth because the others devices are to much expensive to our budget. The biggest trouble we had in the beginning was the battery duration, because of thar we put the 4 Sanyo 18650 battery pack (13600 mhA more or less, 3.7v).
I always configure our audiomths at 256Khz rate, or 250 in the lastest App version. I don´t remember the exact number of hour per night, but at least was eight hours per night without sleep- record cicle.
No I'm talking about rechargeable lithium-ion, not the NiMH. I've used NiMH before, a couple different brands. But I wanted to try rechargeable lithium-ion because they should in theory last longer.
Great, thanks! Just wanted to make sure they were at least compatible before I tried them. I'm going to have them run continuously at a high sample rate just to see how long they end up lasting.
Yes I have been using standard AA NiMH batteries fore my AudioMoth and they worked out fine. You probably want to take care that you pick a proper brand with reliable performance. I have been using the ones from Eneloop/Panasonic.
Ah, I’d forgotten these existed. We’ve never tried them but they should work fine. I can’t find a decent discharge curve plot for them but they claim to maintain close to 1.5V over their capacity. They have some additional voltage regulation inside them which might create some additional noise but worth trying.
