What do I have to know about power banks, to be able to Frankenstein multiple batteries to a single controller and have a single large power supply?
>>108507127just get a car battery
>>108507127Not much, if you keep the charge discharge controller, a lot if you want to make it yourself and not set yourself on fire
>>108507155There's only 60,000mAh in a car battery
>>108507127I believe if you put a shottky diode on a positive terminal, wire all grounds together, you can power whatever the fuck you want. As long as you don't overload it, because they will fall back to some sort of protection mode, could be a fuse that just pops and needs replacement. Also they are not the same, because of differences in resistance you will not get 100% of max Amperage from each of them. Some will contribute more, some will do less. So you will be restricted in terms of capacity of the fastest discharging one, probably. Some will have energy left, but it would be unusable if current is too big (requires 3 banks, while you are left with 2).Just double check what I said with LLM, it's probably right, but I'm not an actually electrician, you cannot take my word. Also charging them would be manual in this setup. You disconnect them all and charge each separately. You can make it smart too, but it's slightly more complicated and depends on specs and features of your particular hardware. Make a mistake and you get burned fuses or your house etc.
If you really, really just want a big battery, buy a LiFePO4 Lithium Deep Cycle battery. They are designed for RVs, trailer-homes, caravans, boats, etc... Anywhere you'd want a shitload of power for running water pumps and other off-grid living necessities. They are fucking massive and heavy, and usually have built-in protection circuits. Some even have shit like Bluetooth so you can use an app to monitor the battery's status.Pair it with a multi-chemistry RV charger set to Lithium mode.
>>108507127you want to strip powerbanks for cells? am i reading this right?
If you have to ask this you are a fire hazard.
>>108507559200 ah lithium battery frfr
>>108507559I kneel.
>>108507127What do you intend on powering that a large battery pack or a smaller car battery can't accomplish on its own?>>108507559This, I have a 640Wh LiFePO4 battery I use to power my astrophotography and telescope setup, and it's come in handy in a multitude of other ways, too. Normally, I can just use a 90Wh battery bank with a USB-C PD-to-12V DC 5.5mm cable instead, though.
