Good deals on LiFePO4 batteries

[Andrewr05]

I came across a good deal on eBay today on some batteries and wanted to share.
And I figured this could also be used as a perpetual thread where we talk about goo deals we've found, recommended brands and vice versa which to stay away from.

These are a very good deal-
EcoWorthy 48v 50Ah $368 shipped
(use the coupon code that automatically comes up when you check out)

$154 per kWh

You could Get a Growatt 3k and two of these batteries and it'd be only a little bit over the cost of one normal 48v 100ah "server rack" style battery alone.

I would humbly suggest this variant because they're easily stackable, same coupon code and final price: https://www.ebay.com/itm/126141151527

I have 2x of a slightly older ecoworthy 48v 50AH design. No issues for almost a year. Moderate usage. Outside of winter they experience daily cycling from 100% to around 20% with around a 15 amp load on the two of them (1500 watt air conditioner split between 2 batteries). Capacity seems on point and possibly a bit more than they advertise.

I was looking at those last night and unless it was me being overtired and not realizing it, I would have sworn that those were over $100 more expensive.
Price must've changed since.

Yeah I would use those instead.

This would make a nice little system-

3000W 48V GroWatt AIO $499 shipped
6,000W surge
50Ah 48V EcoWorthy LiFePO4 (2x) $735 shipped ($367.5 each)
4,800kWh of battery capacity

These 12V 50Ah EcoWorthy batteries are $91 shipped!
(but you have to buy at least two to get the deal)

Can I get 4 of the 10Ah and connect them in series to equal 48V? Or are the connectors too small?

You COULD , yes.

But you may have issues with them staying in sync with each other.

What use would you have for a 480Ah setup?

 

[G00SE]

Not bad. Didn’t click buy but they seem like they’d be neat for a cart build for someone

 

[Andrewr05]

Man, I keep forgetting some of y'all have to pay tax on online purchase.
Ouch.

4 of the 12V nominal 10 Ah batteries in series would only be a 10 Ah 48V system. Not worth the trouble.

 

[jberger]

Is there any app or software available for these batteries?
They look like a great way to upgrade a Ryobi 48V mower but I can't find anything that would let you know exactly what the BMS is seeing.
The specs also appear to be different based on where you look. Sometimes it says 200a peak, other places 300a peak.

 

[Andrewr05]

These are on sale again, nowhere near the deal they were before, but $504 a piece when you buy 2.

DC House 48V 50Ah are now $476 a piece.

Need that 20% coupon again!

 

[Andrewr05]

Need that 20% coupon again!

Definitely!

But $475 is still a damn good deal!

Though 20% off adds up pretty good.

eBay has the 15% off deal for Refurb stuff again.

Which you may not want to necessarily buy refurb batteries, but inverters or Power Stations or any other electronics stuff may be available.
