DIY 2S 3000mah Li-Ion battery upgrade for Fat Shark goggles |
24-Mar-2016, 09:03 AM Great idea and video!! I used to make packs out of A123's for RC aircraft. But the 18650's were only 1100mAh. With the new high-capacity vaping batteries, (and for this application), this is perfect! Those are 18650's - correct? Was any particular brand best for soldering? 24-Mar-2016, 03:56 PM How do you charge them ?? 24-Mar-2016, 04:25 PM 24-Mar-2016, 09:23 PM (This post was last modified: 24-Mar-2016, 09:26 PM by T-Bone FPV.) On my charger there is a li-ion setting. I just use the fatshark charge lead and balance charge them at 3amps. But I really don't see why lipo setting wouldnt work. They still charge to 4.2v/cell.

Yeah 18650s and I just bought the highest reviewed ones I could for the lowest price on Amazon and they worked just fine 10-Jul-2016, 02:22 AM Finay got around to making a couple of these. Thanks TJ for posting this, great diy project! If it isn't broke, fix it anyways! 24-Jul-2016, 12:22 PM what heat shrink is that normal or pvc 28-Jul-2016, 10:45 PM (24-Jul-2016, 12:22 PM)Ahmad Ilyas Wrote: what heat shrink is that it does not matter, does it? DIY my way through as I allways do! 30-Aug-2016, 01:24 AM 30-Aug-2016, 06:23 AM Its a standard 5.5 x 2.1 mm plug like this one: https://m.aliexpress.com/item/3270355332...&#autostay If you guys want to add a battery indicator: http://www.banggood.com/1-5S-Lipo-Batter...73721.html Will the goggles prevent draining the battery completely, or should we use 18650's with internal protection curcuit like theese batteries? http://www.banggood.com/2PCS-NCR-18650B-...90990.html 09-Sep-2016, 01:48 PM I've been thinking of doing this for a while. The Fat Shark battery is just terrible! When I charge mine, it jumps to 8.5 volts almost instantly, and the remaining mAh are pumped in between 8.5 and 8.6 volts. 10-Sep-2016, 04:13 AM Great tutorial TJ. I put one of these together last week. It was a pleasant surprise how easily the terminals took the solder, I thought it would be a battle. I didn't have the wide heatshrink so I just wrapped a few more layers of electrical tape. Works great. Thanks for posting. 12-Sep-2016, 06:21 PM Is it dangerous to solder directly onto a battery? That seems unsafe. 27-Oct-2016, 05:05 PM So if I use a 18650 series battery sled, so I can charge the battery independently on an18650 charger..... I'll only need to connect the pos and neg from the balance plug to power the fan? |
