Ideas for using an inexpensive DC-DC boost converter / power supply

[john61ct]

I'm thinking units like this

DC10-60V 30A 1500W To 12-90V Boost Converter / Power Supply Module
https://www.ebay.com/itm/1500W-30A-I...-/131932153909

also here looks similar
https://m.banggood.com/DC10-60V-30A-...p-1076169.html

could be used from nominal 12V power, even when away from shore power, for

1. powering laptops, other native-DC-but-over-12V electronics

2. 24V devices mechanical devices, appropriate currents of course

(there are also 50A versions available, likely even higher, but gets pricier of course)

3. equalizing 12V battery units

4. feeding a versatile "hobby charger" like iCharger 4010 Duo, for testing / maintaining / balancing LFP cells

5. as a standalone DC-DC "charger", actually just a power supply, you must "be the regulator / controller

6. as above, but specifically to test / implement the "hybrid LFP/lead" idea of finishing the long tail charge required to get lead batts to 100% Full, from an LFP bank

Add possible **new** use cases if you have more ideas!

And please feel free to discuss these ideas in general here, **except** for that last one #6; for that, please post here http://www.cruisersforum.com/forums/...-206424-3.html
to continue that discussion (and read it first!)

Let's also avoid general denigrating of supply chains, "cheap Chinese" issues, other than links to specific units you think would be better for one or more uses. Price is no object at this stage,

so e.g. comparisons to the likes of Charles Sterling's fine BB line, stuff by Victron, Magnum, Mastervolt, Samlex etc would be great

as well as cheap-Chinese but good reputation sources, like Wangdd22 and Yucoo.

HF / RFI noise issues welcome **only** if you have experience-based feedback on specific units or brands

And please, **no** discussion of generators, inverters or mains-powered converter/charger units, this thread is for nominal 12V DC inputs only.

For "buck" converters stepping **down** from higher voltages **to** 12V, tack on to this thread, http://www.cruisersforum.com/forums/...4v-209510.html
or start a new one, it's easy and Free!

Of course any discussion of these or other appropriate specific hardware units is welcome, in fact the main topic of this thread.
