Even if that is the case, it applies to batteries of all capacities. But the higher the capacity, the later the voltage drop. For me, I still prefer to use the most powerful 18650 batteries from a reputable manufacturer.

With the CM5, you generally face the fact that its current draw is significantly higher than that of the CM4. And the higher the current consumption, the earlier the voltage drop.

Radxa CM5 is even more demanding
Yeah these 10000 mAh batteries are very interesting, but the 18650 is very much where itās at. Much easier to source with massive amounts of work and testing already done on them due to their use in vapes. And with either a removable battery door, a good screwdriver, or a change of the rear screws to something tool free it is trivially easy to swap the batteries. With the tool free screws I installed it takes less than a minute to do. And you can hot swap them as long as your batteries arenāt too dead already. The battery packs are certainly interesting and I canāt wait to see where it all goes, but I can do a whole days work with only like five minutes of downtime just swapping 18650s already
I gather youāre referring to the NVMe drives - does anyone know where thatās documented? I didnāt know there could be any drive incompatibility beyond application differences, like PCI vs. mSATA.
I am still struggling with this issue so the drive needing to be lower power sounds plausible.
Using 2 x 5000mah IMHO is the right answer to provide the correct current while maintaining capacity.
But honestly, iām still cautious about battery charge protection when we wire them in parallel this way. The uConsole itself doesnāt do much to protect backflow. Does the LiPo protection board on the batteries suffice?
Youāre being a bit overly cautious. Even if the battery voltages are inconsistent, they will eventually reach a dynamic equilibrium. In many products, parallel-connected batteries do not have individual reverse current protection.

I think the two 500mAh batteries in parallel is the way to go. Your testing will prove this.
Maybe i am indeed overly cautious! And i do admit that technically, you are correct.
Electrically, using 2 x 5000mah would be perfect.
The 1 x LiPo current limit limitation was the main reason holding me back from moving to LiPo. But longer battery life is really tempting.
Iād be happy to pick up a battery pack by hackersgadget based on this config. And i think that 2x5000mah might have the chance of being physically a little smaller too heheheh.
Batteries in parallel are like communicating vessels. It can get very hot if one is empty and the other one is full.
yes, when paralleling two batteries they should be at the same state of charge, but once theyāre parallel they wonāt really end up in the state you describe

So if you parallel two batteries, they should be the same model, with similar voltage levels and internal resistances.

Meet the new supercharged CM5 Uconsole. New front customised case from @lululvlv and new touchpad trackpad much better for navigation goodbye trackball. Nice new cooler on the CM5 keeps temps way down. And has the full hackerGadgets AIO2 kit. Cm4 is done the same soon next up to finish the radxa CM5 with the same mods then review time.

Whatās the story with that CM5 cooler and trackpad ?, very interestingā¦

@vileer what is the possibility of populating the 4g module to the aio board is it doable. This would make it the ultimate mobile device.
Threy are very good and adds to the uconsoles upgrades I will be reviewing them once I am done building the last unit waiting for some more mods.

Downclock a little yet still see performance benefit over CM4 ?
I may design a LTE/4G dongle for it.
