You can put more than one cable in each hole.
4 raw lifepo4 cells cost around £20 on aliexpress for what I believe is a similar capacity (unless I have it completely wrong, which I probably do), would DIY be worth the effort for cost-saving? but curious to see what you guys think
Gotcha haha, I knew I had it wrong but just wanted to checkLol , no.

Your maths is correct, except that you left off things like a charger, thermometers and battery management, which are necessary for LiFePO4 cells. Also, the quality of those cells may be a bit questionable compared to what you will get in a professionally made battery. But some of the dashcam battery manufacturers must be making a lot of profit!4 raw lifepo4 cells cost around £20 on aliexpress for what I believe is a similar capacity (unless I have it completely wrong, which I probably do), would DIY be worth the effort for cost-saving? but curious to see what you guys think
there are more things to be considered when pricing a product . You paying for their experience , their R&D , their time and effort , and the materials that when all is combined together they produce the final product .Your maths is correct, except that you left off things like a charger, thermometers and battery management, which are necessary for LiFePO4 cells.

Yes, you are paying for their work, this is not something that you can easily make at home.there are more things to be considered when pricing a product .

i guess none of you runs his own business , and you are just consumers ?
Mine was sent with UPS from the UK.the told me they ship out of europe to avoid import tax
I've found that my normal driving doesn't charge the 6200LFP enough to run both my A139 3CH and SG9663DR in parking mode for 8 hours. Today the A139 recorded for 6 hours, and the DR recorded for 7 hours - the low voltage cutoffs in both the HW kits are both set to 12.4V, but probably vary a bit in practice.Ordered the HW version tonight. Planning to run both A139 and SG9663DR via HW kits, and a Mobius 4K via a 5V USB socket extension.
