Thoughts on the AOlithium 51.2 server rack lithium battery -48v

andliu said:
I just purchased and found a work around. the price sent up to $1099 per battery and without wires but, if you go to the Aolithium us website then click on LIFEPO4 battery at the top. you'll see whole page of batteries scroll down to the bottom and find the two rack, three rack, four rack for the per battery price and includes all cables. Now for the better Canadian discount... I am Canadian myself, Do not purchase on the Canadian site, as per battery is $1599 or 2 for $3167. i purchased on US site with code Aolithium01 (1%) additional off - after conversion it is $2750 Canadian. When you get to the end of the check out - you can choose Canada. - edited my post just realize they are referral links, not mine...you do save more msg me privately if you want

I'd be curious to see if this works out for you, I'd assume if you purchased from the USA site it would ship from the US and you'd be subject to duties and taxes once it crosses the border, in that case, you'd be a few hundred over $3167 with the unfavorable exchange rate at the moment.

I dont think they'll actually ship from USA, cause it would cost them a few hundred, i thought of that as well. i would pretty much be break even point
 
I've had two of these for a couple weeks now. They seem to be solid, but came not well top balanced, they were kicking out on individual cell protection at like 53.5V pack voltage. Normal cycling did not give them enough dwell at the higher voltages to balance. I took them offline 5 days ago to slowly bring up the voltage to balance them properly. I have discovered that the BMS has a crazy slow balance current. It has been allowing me to increase about .25V/day in a couple steps. I've been looking at getting a HomeAssistant setup and wondering if anyone has been able to pull these in over a cable connection?

The batteries themselves are fused internally and have power switches so the install is a bit cleaner than my DYI batteries
I currently have four batteries paralleled and running to a Lynx distributor. The lynx distributor has a few 100A fuses that I was using with my DYI batteries but for the aolithium I'm just using it as a glorified bus bar. I have two 400 Amp class T fuses sitting between the distributor and my two inverters (one each).

However I'm going to change this and run six batteries to bus bar then from the bus bar to the lynx distributor. I'm going to stick with the 400A class T fuses. I think the main thing to focus on is protection between the full battery stack and the inverters since each battery has protection built into it.

So I'm gathering that running to a bus bar is preferable to doing the parallel daisy chain method that they show? Does the daisy chain cause an amp draw limitation?

Depends on what you need the system to do. If typical and max amps out of the stack is less than the rating of the cables (25mm2 = ~3-4 AWG) then you will be just fine with the parallel cables and one set of longer inverter connection cables. If your inverter can draw more than 125A from the pack then you should use the buss-bar and connect each pack to it.. then use 2/0 or thicker to connect to the inverter.

For current sharing issues it is better to have the buss-bar... again this is likely more of an issue if you have a bigger system taxing the stack to a greater extent.

Would have been great if Will could have tested the stack with a since 6548 or the 6000XP to see how it works for lighter use-cases but that ship has sailed.. They have changed the BMS hardware and software (improved?) and dropped the price nearly in half over the last year.
 
Thank you Detritalgeo. I'm building a system for my 91 newell coach, using a victron 48/15000 240v/60hz Euro quattro inverter/charger going to their 100A autotransformer to get split phase to my panel. I've ordered a couple of Lynx distributors and power in, because I was originally planning to use the 8D size type batteries, but these seem too good to pass up. I will utilize those instead.
 
Had 2 units delivered today. Order was processed on the 25th and looks like freight logistics got it moving in early December. Nothing wrong with shipping times but seems AOLithium customer support does not have access to the waybill records of shipments out of the Canadian warehouse agent. Tracking is possible but didn't get the number from AOLithium.

The packaging is wild, plywood crate on a pallet with metal corner reinforcement. Battery is switched by chunky foam blocks and a huge bag of silica dessicant.Very solid.. The cables were in a box on top and flattened but no damage. Turned one pack on and it's at 30 SOC and all cells are within 0.002 mV or so.

Overall looks great but time will tell.

I just took delivery of two of these. Can confirm packaging was good and freight vendor was random.

Anyone set one of these up with a Growatt SPF 3500TL LVM-US and get the communication working correctly?

Inverter communication is the wildcard here.. I will be working on getting communications sorted out for my Voltronic 6548 type AIO.. No luck yet.

If everyone who gets comes working reports here we can better interpret the instructions in the user guide. My kit came with a network cable for connecting to PC but there is virtually no guidance on how it can be used.

For growatt believe that you need DIPS 5 and 6 to be on.

Yes, that was my interpretation too. This sets it to CAN.
Growatt has settings for Lithium with communication, with a second setting required that the manual tells you to reach out to Growatt to confirm.
I did, and the Growatt guy told me to set the inverter to manual and enter in the voltages manually. Sigh...
And - holy crap the fans are loud on the Growatt.

Yes I think the AOLithium BMS is setup for CAN communication but not sure the RS485 option (for voltronic) is ready to go out of the box.

If you are able to get communication going for growatt let us know.

Really want to find out the BMS manufacturer and see if any of the BMS configuration apps will read the BMS data.
 
This morning, after 12 days of slowly bringing up the voltage, managing the high cells at no more than 3.6V so the BMS can balance, one of my batteries finally leveled out at 3.56xV for all 16 cells, 57.0V overall. I’m putting it back into service. The other still has a low cell at 3.368V and will need some more time. It would have been nice if these all came top balanced. I’m guessing the BMS is bleeding off about an amp hour per day, that’s a heck of a cell level SOC difference as shipped and a huge handicap to cycle capacity until fully balanced.

I heard back from support who has to ask the engineers...

Apparently the pack will support communication with Voltronic 485 but they still have not illustrated to process or settings to use.

They did say that for Voltronic comms over RS485 they only support one singe pack to one inverter... very odd. I guess that is what the "Stand Alone" means in the inverter com settings table. Pretty lame limitation.

Would still be interested if anyone with CAN-based AIO's have an easier time with getting comms up. What does LuxPower use?

they also said their BMS software is internal only. Lame again..

I found on their site somewhere the statement “Aolithium batteries use JBD Smart BMS”

JBD-UP16S010 really looks like the one of the rack batteries.

This guy seems to have found some BMS documentation... its not a well known unit from my knowledge..

AOlithium -48v batteries to communicate with All-in-one (pylontech)

I have 4 - AOLITHIUM 51.2v 100ah Server Rack Lithium LiFePO4 Battery. In the manual its not clear on how to make all 4 communicate with “Pylontech”. All it says is jumper 32 (which is DIP 6-on) has to be set. It also is not clean if “slave 0” would be considered the first battery. Can someone...

@Kremer Once these batteries come back into stock, is it possible to top balance these batteries using the inverter/charger if I set the voltage for the battery profile and step it up like you are with the bench charger? Or would I be better off getting a 48v golfcart charger where I can set the voltage at a lower amperage? My inverter is a victron quattro 48/15000.
