This is very tempting. Have been hoping for a 280 or 314ah battery for this price with bluetooth but that may not happen again.

Our community has rated this post as helpful. If you agree, why not thank

Check out this review. These appear to be plagued with cell balancing issues since the bms only balances during charging. Ymmv

In March and June the 280Ah Ecoworthy batteries were $215 and $244 including tax.

Bought one each time but needing one more now. They don't seem to make the plastic case anymore so figure those days may be over.

Just purchased using the code. First one was $33 off. Second, I purchased some misc other things to bring it up $10, then used the $35 off coupon. Basically free $10 worth of extra stuff. Don't forget to use C*sh back 18%. Makes it a no brainer.

Okay looks like Will has done some research on them from what he did and I saw.(I am speaking about the brand not this exact battery).. Not great for mobile applications seems to have good capacity... Someone here says they don't balance well. Would that just mean get an external battery balance to keep it running strong?

What's an external battery balance? Do you have any reference links so I can learn more?

Finally decided to pull the trigger and appears the price spiked up to 475 before coupon.

Edit: Just checked again and it's back to the sale price so I ordered one.

I don't think you could balance these externally. You can get balancers to balance multiple 12v batteries that are in series, but each battery has multiple internal cells and you can't balance it unless you physically open the battery and replace the BMS which isn't easily doable on most batteries.

OK, so the issue that other people brought up was that it only does the balancing while it's charging. Why is that an issue?
