Not for engine starting. Great for a house battery for lights, fish finder, music, trolling motor, etc
FYI the bms is 150a, so this battery will support roughly 2000w discharge which is pretty good
This battery is pretty awesome for the price. But I'd test it to make sure batteries are balanced (Overkill Solar on app stores is good, but don't mess w/ any battery settings b/c you can mess it up). Most batteries they produce are great, but many have reported here defective units that were replaced promptly once reported. You can look at previous deal threads for this battery for a more in depth description on these topics.

I missed the previous 100AH sale but looks like its back active again for the same price.

Even the DC house from same manufacturer also back on sale.

I have min kotta 30lb thrust trolling motor and planning to use it with my inflatable boat. Which one you all recommend?

DC House is just fine...if you're not in a hurry, might wait for a stackable coupon from eBay.

I love mine. I first bought a hundred amp hour for my trolling motor. I ended up moving that to support all the electronics on the boat and I ended up buying this one 150 amp hour for the trolling motor. I love the Bluetooth activity and I could run my Minn Kota Terova 55 lb trolling motor all day and still have 50% battery left after 8 hours.

OH that makes complete sense they allow it to be configured, interesting they dont list that in the details. Thanks for the info!
Browsing DC House site, I discovered something new to add to this...the LVC is 19F, ASSUMING it is charging. Below 19 it stops, and will resume RECOVERY charging at 33F. I think the rationale is that when charging, the cell absorption can withstand going below freezing, but starting a charge below freezing would damage the cell.

Edit: brain refresh, you can USE the battery (charge/discharge) below freezing, but you can't RECHARGE battery until over freezing temps.

Quote from tonight :
I just got a delta 2 with the previous FP deal and it's my first foray into solar. Can you talk more about your setup, how do you charge the battery in the first place? Can you use the Delta 2 to charge it as well without a lot of inefficiency?
Sure. External 12V batteries like this are a great way to expand capacity at a small fraction of the price of the branded extra batteries. They do have a few limitations and aren't quite as plug and play, however.
Above, I described the way to charge the Delta from the battery at about 192W, using an O-ring to XT-60i connector.
To charge the 12V battery, the simplest way is to use a car battery charger (but preferably one that has an LFP mode). You can get a 12V, 10A battery charger on Amazon for $15-$20. It plugs into a wall outlet, and has alligator clamps to attach to the battery. It is relatively slow but does the job (there are higher amp options that cost more). This CAN technically plug into one of the 120V outlets on the Delta but that is a pretty inefficient way to do it. For my use case, I charge the 12V battery from the wall and keep it mostly charged for emergency backup situations.
You can also use the EcoFlow 800W alternator charger (lists at $600 but goes on sale for $200) for much faster charging and recharging of an external battery from the Delta.
A third option would be to buy an MPPT solar charge controller and recharge the 12V battery from solar panels. (Or, what I sometimes do, input the solar panels into the Delta then plug the 12V battery charger into the Delta and use solar to recharge the external battery. Will have some inverter loss but it's free solar energy anyway!)

I the ebay listing is you look up under the description it discusses using these as trolling motors. These should be good for anything besides as a starting battery in my research.
You mean I can use this instead of my trolling motor?

These are solid batteries. I ordered last go around and they ran out/upgraded me to the metal case variant. I use it with a 1000W inverter for charging RC batteries, running a 32" TV to watch movies off grid in our trailer, keeping phones charged, and for my boats trolling motor.

My only gripe is it's huge/heavy. Is not a standard size 24 as it's taller.

Can I connect three in parallel (so I get 12V 5760Wh) and use the same 1000w inverter? I'm trying to find a way to power the fridge for at least 3 days.

You can hook two of these up together to make it 24v

I have a 48v mower so I'm going to use 4 of these to power it.

It matters how you wire it. For example one method would give you 600 ah at 12v. Other way would give you 150ah at 48v. At least that's my understanding

You can but your current would be quite high, about 80 amps, so you would need some pretty big gauge wires to avoid overheating and risks of fire depending on the distance between the batteries and your inverter. Generally it would be better to hook up in series to get a higher voltage and therefore lower current to decrease the need for thicker wires which can be pricey.

Ummm what are you talking about the the max that fridge would draw would be 20 amps and most of the time less 12 ga wire could handle that, just put a 4 ga wire from the inverter to the battery (runs about $20) and run an extention cable to the fridge.

If it's a short distance of a couple feet from the battery to the inverter, then a 4ga wire should be more than sufficient as that should be able to handle 80 amps with an acceptable voltage drop of < 2%. Since the inverter converts the DC voltage to AC at 120V, then it wouldn't be a problem going from the inverter to your fridge at a max 1000W (1000/120 so about 8 amps) using a standard 12-16 ga wire.
