SoC = State of Charge.

When replying to someone who has asked a question that indicates they don't have much background in the topic, it's nice to avoid using industry-specific acronyms and abbreviations.

FYI the 6000 cycles of LF280K cells is based on research using a specific amount of cell compression, around 600 pounds. The cells themselves aren't different, just the datasheet with the word 'compression'. I guarantee this company did no better than tie a zip tie around these cells. That would vary compression between too much and too little as the cells naturally swell and shrink. Basically this is no different than any previous 3000 cycle battery, which would still be a daily cycle for 8 years.

You think this can be used as a backup for a sump pump?
LiFePo4 batteries lose capacity when stored at a high SoC (state of charge), as it would be with a backup sump pump. To what extent is up for debate. Here is one study that goes into some depth. Check out figure 10.
https://www.mdpi.com/1996-1073/14/6/1732

I almost bought a LiFePo4 when my deep cycle lead acid battery died, but ended up sticking with another (high quality/name brand) deep cycle. In 4 year when it needs to be replaced again, I'm hoping there will be more real world data available.

Edited for clarity

Quote from Caminante :
These batteries are really coming down in price. I built a 280Ah battery 3 years ago for $750 which was a bargain at the time, there's just not much incentive to do that anymore. A few notes, though...
  • It doesn't look like the BMS in this battery has low-temp shut-off for charging, so you'll have to be careful not to charge below 0F, being conservative.
  • Max charge current is 160A, so you'll have to put a DC-DC converter between it and your alternator if your application includes charging from an alternator (van, travel trailer, etc.).
  • They do mention that charging methods are a battery charger (preferably lifepo4), solar controller, or DC-DC converter, so it's not really drop-and-replace for a lead-acid battery, but it's a nice amount of capacity at a good price even with those extra expenses.
Question. I have a 12v 400a alternator, would I need a dc to dc converter?

May be a dumb question. But I have a 48v Ryobi zero turn mower which I despise (mainly due to battery)

Is it possible/ would it make any sense to replace the lead acid batteries with this?

I would love to sell my mower and buy a gas, but I bought this before covid and prices for gas mowers have gone up so much, and there is a 80v generation out so my mower has greatly lost value.

Thanks !

Edit to ask: I have a 100 ah 48 v battery. I didn't realize this is 280ah. I guess it wouldn't logistically make sense to chain 4 12v batteries because then I'd have a 1100 ah battery?

Yes you can have both a 12v 1120ah battery or a 48v 280ah battery depending on if you connect them in series or parallel. You could use this with the addition of a 48v golf cart battery charger they have models that will charge both lifepo4 and lead acid batteries. Just to point out, not only will these have much higher capacity compared to lead acid, they will also be much lighter comparatively.

May I ask which backup battery you bought? Mine will need replaced within the year and would like to start shopping now.

TIA woot

I got the "Duracell Ultra 12V 110AH 800CCA AGM Deep Cycle Marine & RV Battery". You can certainly find less expensive batteries, but you want an AGM Deep Cycle with a good warranty.

Wayne Pumps sells a 75 AH (lower rated AH, so it won't run as long) but may be slightly cheaper.

There is a guy on YouTube, aging Wheels, he went above and beyond changing out the batteries on his Ryobi rider. He loves it now. You do not need to add a separate charger and BMS like he did.

All you need is 48 volts worth of batteries, look at golf cart conversion kits for the right dimensions for that mower.

If it were me, I would. You might have the 160A headroom when all your other loads are maxed, but a DC-DC converter like the Renogy will condition the voltage better and give you the right profile to safely charge to max capacity. It also has an input for turning the converter on and off which is convenient for a switch or a digital input to control when you charge.

You could not charge this with an ecoflow alternator. But you could essentially treat this like your vehicles 12v battery and run the ecoflow alternator to charge other things at a much higher volt/wattage...
