but in the case of a li-po or li-ion like in a dashcam/actioncam or even the big packs used in an electric or hybrid car, if you discharge them too fast or too far, it can cause the battery to swell and/or rupture, releasing flammable gasses such as hydrogen. in the case of a lead-acid, ni-cad or ni-mh, you simply won't be able to recharge it anymore if you drain it too far - no real danger of fire/explosion. Maybe if i buy more/larger batteries for the quad, i'll get an imax, but till then, i don't really NEED one.įor those who don't understand about batteries - it's actually harmful and sometimes even dangerous to completely discharge a rechargeable battery, whether it's a lead-acid battery like the one in your car, or smaller battery packs for electronics (phones, toys, dashcams, etc) made with nickel-cadmium/lithium-polymer/lithium-ion/nickel-metal-hydride/etc.Īlkaline/dry disposables don't matter since you can't recharge them anyway, so it's safe to run them completely flat.
Now you have me wanting to buy an imax charger instead of the simple little 3S balance charger that came with my quadcopter. The test (part of) with explanations and details: SJCam Battery / discharge 0.5A - 681 / 700 / 721 mAhĠ.5A Discharge - charged by camera (Lowest / Medium / Highest) GitUp Battery / discharge 0.5A - 641 / 688 / 704 mAh SJCam Battery / charge 0.3A / discharge 0.5A - 679 / 715 / 743 mAhĠ.5A Discharge - charged with Dual Slot (Lowest / Medium / Highest) GitUp Battery / charge 0.3A / discharge 0.5A - 658 / 708 / 727 mAh SJCam Battery / charge 0.1A / discharge 0.3A - 687 / 730 / 763 mAhĠ.5A Discharge - charged with IMAX (Lowest / Medium / Highest) GitUp Battery / charge 0.1A / discharge 0.3A - 691 / 745 / 780 mAh I have also investigated the dual charger a bit and it's open voltage varies between 4.35 to 4.45 which seems too high, so it's possible that mine is faulty.Ġ.3A Discharge - charged with IMAX (Lowest / Medium / Highest) Taken this into account and knowing that the Git2 has lower power consumption that the SJCam it means that the actual usable capacity of the GitUp Battery is larger than the SJ Battery The SJ Battery works OK with the dual charger. The SJ Battery keeps capacity a bit better under higher load The SJ Battery has more consistent capacity regardless of the discharge rate.
The Git battery has bigger capacity by a margin under lighter load compared to my SJ battery. The Git battery loses capacity faster under high load, but has better capacity at low loads (completely normal) The Git battery does not like my dual charger. Here are the summary of the results and conclusions This means that if the voltage will not drop to fast in the next few hours we may get a capacity in the range of 900mAh.
Gitup git2 vs sj5000x series#
I'm also running a second series of tests with a low 100mA discharge current and by reading the voltage until now at a 30% discharge i have pulled 354 mAh. My first battery testing series is finished and the first conclusions are below. It seems the choice of camera is more important than the choice of battery, and having chosen your camera you still have a choice of battery, unless of course you try to fit a GitUp battery in an SJCAM and find that it is too big to go in the hole! Presumably more data equals more image detail.Īt 60fps instead of 30fps, record times are less and I saw only 19% more record time for the Git2 instead of 24% more. So using the same battery the Git2 records for 24% longer than the SJ5000X Elite while storing nearly 50% more data! Mobius: 130 minutes (fitted with large battery - ) Git1: 120 minutes (from previous testing.)
Gitup git2 vs sj5000x windows#
The record time was measured by looking at the minutes recorded using Windows file explorer and averaging two runs.
I charged the battery in the camera to be tested until the camera said it was full, then set it recording. The cameras where set to 1080p30 with gyro off for comparison with less capable cameras like the Git1 and Mobius. I used my best SJCAM battery since GitUp batteries can be hard to fit in an SJCAM, put it in the SJ5000 first, then the Git2, then repeated. Since record time is the most important, I have tested the record time for the Git2 and SJ5000X Elite using the same battery.
