Hi,
Be my guest. Spend double the money for 1/2 the capacity.
Don ... I spent $400 for my 537 watt-hour Bluetti EB55 using an ultra-safe LiFePO4 lithium battery bank that can be discharged to near zero and can tolerate 2500 or more charge cycles. 537 watt-hours about equals a 45 AH LA or AGM battery. Built into the EB55 is a 700 watt inverter with 1400 watt surge capability, an MPPT solar panel controller, DC down-converters for two kinds of USB ports and a 12v port, plus a 3-mode wide area night light (2 brightness levels and an SOS flasher). All of this is covered by a 2-year warranty and mounted in a convenient little carrying case.
How much cheaper could I have DIY'd the same ... with each part in it warranted for 2 years?
I used to be an electrical engineer, so I probably could have put one together - but should I have?
