    Dashcam Install Help

    Not every day, every hour or so. A 16Gb card can fit less than an hour and a half of video (for DR750S-2CH on high def settings, less than 60 min on 'extreme')

    Dashcam Install Help

    Yes. The B-124 uses that dongle to give you a cigarette lighter port to plug in the dashcam. I installed an on/off switch into that dongle. The battery remains plugged in to my actual cigarette socket all the time so it always charges. As long as my switch is on, the camera gets power from the...

    B-124 battery should easily last 20 hours. If you need it to last several days, can always get a couple of the extension batteries (which each have more power than the normal). They are stack-able.

    My cam is set to 2 or 3 and it doesn't save recordings continuously, but does probably save ~5 min per hour. Even if it's set to 0 though, it's still constantly recording (in case of impact) the only difference is it doesn't save those files. I'm not sure the power difference between the 2 is...

    Update on running the Blackvue DR750S-2CH from the B-124 + 2 TQKA '20000mah' packs: Been working fantastic for the past 3 months. I've left the car parked over the weekend a few times and it still lasted to Monday in parking mode. The roughly 1.5 hours I drive per day seems to be enough to keep...

    May be able to get away with a simple 5v to 12v converter like: http://a.co/7IElcEw One thing to note is a Blackvue at ~4W is more than twice as much power as the cam in that video is pulling. But assuming you can source that much power from the same wire, should work.

    I wasn't trying to give a fair comparison. I'm not suggesting that 4 watts is way above what's appropriate for a camera (though it could be more efficient), just that 4 watts is a lot of electricity. Because as you pointed out, it needs to do a lot. I'm not trying to make an argument that...

    Depends on how you look at it. 4 watts is significantly more than I would have expected. For reference, a TI-83 programmable calculator (20 year old technology, which I remember sucking down batteries) consumes just 0.01W while turned on and under 0.05W while calculating/graphing constantly. In...

    Dashcam Install Help

    Here's a photo of the setup. I put everything in the armrest compartment. There's more space in the other center-console area (under the phone charging shelf) but I use that for general storage so preferred to give up the armrest space. Also having the cigarette lighter there made the wiring...

    Dashcam Install Help

    YES. They use LiFePO4 battery cells which won't expand, won't blow up, and aren't even flammable if you hold a flame to them (Important for a car environment) This is why there's so much discussion around the tqka 20,000mAh packs which are some of the only LiFePO4 packs available at a reasonable...

    Dashcam Install Help

    I have my cam (DR750S-2CH) connected to the Blackvue battery pack (B-124) with a switch to turn off the dash cam if I'm going to be parked a really long time. I also got a couple of the tqka 20,000mAh packs a few of us were talking about earlier on this thread, took them apart to harvest their...

    Took the battery apart yesterday. It did not yield easily. The top and bottom have essentially a thick sticker which comes off easy enough. then there are 4 tiny phillips screwps on each. The bottom has a metal plate that comes off after unscrewing them. The top is glued on so even after the...

    I think I'll try to make my own battery using the cells from this TQKA. Pretty much all you need are the LiFePO4 cells and a battery management system (BMS). They are rated for how many cells they can charge/balance in series (S). In this case, I would make a "4S" battery (Four 3.2v cells in...

    Had a chance to test the battery today and wanted to share: tldr: I set it up to draw ~10watts and to my surprise, it actually lasted 5 hours! Actual total power consumed: 46.9Wh During testing, the voltage fluxuated between 4.257V and 4.396V. Not fantastic, especially when you consider that...

    There is absolutely no way that battery bank meets it's rated capacity... but I'm curious enough to find out. Just ordered one and I'll test it this weekend.
