I have one of these, really like it. Also have an Eco Worthy 100ah wall battery. Tempted to buy three more of these to run in series with the wall battery. Anyone done this?

I run 4 of these in series and bond to Pecron E3600LFP as extra battery. Work great, but do get a good equalizer to balance between the four.

Which balancer do you use? I have the LiTime balancer on four of these batteries, but a battery or two will still go out of balance after awhile. I had to bring my bulk/absorption charge down to 55.8v so a single battery bms won't trigger over voltage.

I meant to bite at $220. I don't know that we will see that price again for a while, if ever with the state of things.

If I need to lock it in by September should I just pay the $30 more and get it before it's $300/325 again?

Any huge breakthroughs I'm missing about to drop the price of LiFePo4?

are these LiFePO4 batts suitable as replacements for regular 12V car batteries?

NO> These are great replacements for deep-cycle Camper, home Solar and such. Not meant as a starter battery, but a huge storage of energy. Plus your Alternator isn't designed to charge these and will most likely destroy it. I snagged one back when it was $208. It is nearly 3 x 1 Walmart 29DC battery. So far It is doing great in my small camper. Had to install a cutoff breaker to keep the shore power and Alternator of my truck from damaging it.

thanks for saving me from making a mistake. curious if ali generally sells any conventional 12V batteries that are not as expensive as my dealership charges but still of decent quality.

Keep your eye on Woot. I've purchased 3 AGM 100 ah batteries from them over the past couple months for about $65 each. Mighty Max is the brand name. Seem to work as advertised. FYI, they have bolt type terminals, not posts.

Gonna wait. $220 was a deal hit 2X in the last 6 mos. This is lukewarm at best for Eco Worthy. No matter what happens with tariffs, these things have only gone down in price. Been buying them for last couple of years an need an extra.

I got one. The Bluetooth monitor never worked. Disappointed since that is a key feature

Was that cutoff breaker install pretty easy?
