Experience sharing - Buying a 51.2v 14.33KWH Wall mount battery pack from Shenzhen Basen Tech (US stock)

[wpns]

Interesting, but the devil is in the details. I'd love to back up 6 months and compare pricing (and IP65 rating) to EG4 PowerPro WallMount OutDoor. Those batteries are way too much for the single DIYer, now I gotta go find four strong friends.

I am curious what BMS is in it. Someone from Basen told me they have their own BMS but I don’t buy it, I think is a customised one by changing only the name of pcb.

Let us know if you get the price. Really curious how much that 30kw battery stack will cost.

Ordered another one (280ah) for the similar price I originally paid (at the start of the thread). It seems building battery pack DIY route (with raw cells) is not cost effective anymore even if you value your time to certain extent. The delivery will be in 7-12 days. I will update once received.

I was quoted $1260 for 16 280Ah REPT cells delivered. There's still a decent delta there versus diy, even after adding BMS, breaker/fuse, enclosure etc.

They want $2400 for 15kw battery shipped from China. @2000 shipped from US was deal $2400 not so much

There is a 40 page document on the first post regarding there BMS. Please check it. Hope it will answer your questions.

$2400 is too much. Try negotiating with them. Anything under $2000 with shipping is a good deal. My 2nd battery pack arrived within 7 days.

Now, how about the deviation between cells? How much is when the battery is fully charged? This might indicate the quality of cells and how the balance function acts.

The shipment arrived almost in a week as promised. The packaging was very sturdy (came in a plywood box). It came with extra battery cables, concrete bolts to hang and communication cables. Hooked it up in an hour, it was pretty much seamless. Dragging this monster battery pack (300+ pounds) to its location was the most time consuming part. You really need a friend or two to move this around on an uneven surface. The wheels were very helpful. Currently, working on the Inverter to recognize this new battery. Will update soon.

How is this performing so far?
Does this not have wheels? I thought I saw wheels in the description

Now you’ve got me curious as to what a 10 pack of the EG4 PowerPro would be FOB Shenzhen.
