This is a 48 volt, 100 amp hour LiFePO4 rack battery with Bluetooth that fits solar, UPS, and other 48 to 55 volt DC setups. It stands out for its large 5120 watt hour capacity, state of charge and battery health monitoring, and solid use as a direct DC source or paired with an inverter. The main cautions are that it is only a battery, so it needs an inverter or UPS hardware for AC backup, and its heavy, wide rack form makes e bike mounting awkward. Matching versions over time can also be confusing because the model number stays the same while revisions change.

Dang. So if any camper got 2 units of this and an inverter, they are pretty packed for a short off grid trips with some portable solar panels for redundancy, right?? The price is really tempting and make me want to jump on it even though I havent really got a specific use case for me or my family yet.

Still Slickdeals effect hits me hard.

Just be careful if you are obtaining them over time and want them to match - there are many different versions of this battery as they have made steady improvements on it, however they keep the model number the same which makes things confusing. There is another version they are selling that says cubix 100 in the lower right - not sure the difference.
I've ordered these twice this year from them on Ali express. They ship cubix 100 versions now. Both times I've ordered the regular and they shipped me a cubix. The differences are pretty minor and they all even take the same firmware update. The cubix 100 have a slightly upgraded comms port.

I already own two of these that I purchased from Ecoworthy directly. Purchased two from aliexpress and they are fake. I opened them up and took photos and contacted Ecoworthy. They advised that they are fake as well. Ecoworthy then sent me two legit ones for free and asked me to send them the fake ones, which I did. Since the fake seller on Aliexpress (even though it looks legit) didn't respond to me, I filed a chargeback with my CC company and won the case.

I am currently dealing with EcoWorthy through AliExpress, and this has been, without question, the worst customer service experience I have had in over 50 years. What should have been a simple return has turned into an ongoing, frustrating ordeal. The batteries I purchased do not fit, yet after more than a week, I am still being given the runaround with no resolution in sight. The level of inefficiency, lack of accountability, and overall disregard for the customer is frankly unacceptable. Based on this experience, I strongly caution anyone considering a purchase to think twice. I would not consider buying from this seller again under any circumstances.
