Sump pumps are one of the most boring parts of home ownership. Until that one storm comes and suddenly they’re interesting.
After losing power one time this summer, I got paranoid and decided to build a battery backup. Home Depot had the basement watchdog systems, but they seemed high maintenance and I wanted something that would let me be lazier. I went with a LifePo4 battery system, that will (hopefully) get me 10 to 15 years. The battery charger has a float/storage mode so it can stay on 24/7. Doing some test runs, I think I can get about 400 cycles out of the battery before it hits 0%. I added some additional safety features (DC circuit breaker, GFCI with auto-on, Lithium fire extinguiser, etc), and added some battery powered lights and a basket of hand tools, so in the event the power goes out in the dead of night, something goes wrong, and I have to get my feet wet, everything is there ready to go.


I see the fire extinguisher is mounted in a convenient location should the board catch on fire. Easy to reach, you know, around all the flames.
There’s a second one 10 ft away.
Your concern of fire with the smoke detector and fire extinguisher, is something I strive for with my hobbies. Well done!
Since it’s on the basement, make sure it’s not “made in Briton”
Nothing against the British, it’s an it crowd reference
I’m going to put it there, together with the rest of the fire
To whom it may concern:
FIRE, FIRE, FIRE!!!

Remember to place the monitor just so
at a sea parks?
“They died in a fire? In a sump pump pit?”
Are the seals alright?
Not the scene I was referring to be still applicable
Yeah, I had inverter feed cable just like the one in front of that board almost catch fire. The smell of melting insulation saved the day.
That’s why I have a circuit breaker on the positive feed line. Kills the circuit at the amperage that begins to melt the cable.
