Pack contains 2x UPS modules 12V 1A output (can parallel to get 12V 2A)
This amazing uninterrupted power supply UPS backup circuit module will POWER many stuff at 12V from a 18650 battery or LiPolymer cell with input for charging while feed the load
If main charge supply fails, the circuit will keep your load UP from battery. But can also be used as portable 12V power supply
One 3000mAh lithium cell will power a 12V 5W load( one module @ 0,4A 12V powering hi brithness led table light example) for around 2hours (if you parallel 2 cells, it will last ~4hours supplying 5W@12V continuously)
Module able to supply high power stable 12V up to 1A continuous output(use miniature fan air cooling at more than 0,5A power draw)
All kind of protections, over-load, over-current, thermal , battery management all packed into one high quality module
Circuit thermal optimized and tuned for maximum efficiency conversion DC DC step up boost topology plus battery management/protection voltage @ lithium operating window, 3,0V to 4,2V (max energy extraction from cell and keep safe low cut to protect cell/parallel cells)
Many applications possible, modem , telecommunications backup power , wireless, sensors , arduino , raspbery pi , portable radio, etc
TIP for battery supply optimization using parallel 18650 cells for increased capacity and current output from cells. Also great from reused cells (iS OK secure to mix same type, different capacity/used/new cells to increase greatly capacity and current capability (MAKE SURE same voltage cells at parallel join moment)
