Great review! You really did get it at the best price! Even though the cables and racks now need to be purchased separately, I still hear that Aolithium's batteries are about to go up in price again in April. The batteries I purchased in March 2023 are still working great.
I have two. They came super unbalanced and took three weeks of slowly dialing up the voltage to properly top balance due to the silly slow passive balance current. That said they have performed beautifully once balanced. I just took them offline to check and rebalance, looks like this will take a couple days again.
The long wire that has two batteries on it couldn’t you get better balancing with using the positive on one battery and the negative on the other? And run those to the victron
The battery will support RS485 communications with the Voltronic (6500EX) but AOLithium told me the BMS can only communicate with the first (Master) battery in RS485 mode. Only the CAN communications protocol supports the Master and Slave communications. Make sure you have the correct pin wiring in your custom network cable to get it to work and flip DIP switch #1 up.
I would also suggest the pair that are paralleled is splitting the load between 2 packs so they are more likely to not correctly sense loads under 0.5A per pack?
Last one.. Thanks for the video!... just a note that the 'lifespan' is estiamted to be 15 years but the warranty was 7-8 years when you bought these and recently the warranty quietly changed to 4 years.. still good value though.
Great battery, but I would use this with a heavy duty low frequency, transformer based inverter instead of a high frequency, transformerless inverter charger. The low frequency inverter will last far longer and you'll have a much higher peak power (surge) capacity than a low cost high frequency inverter charger.
I was wondering how well communicating and non communicating banks would work together. What happens when one of the AO batteries depletes itself fully? Does the BMS just limit that batteries workload until its charged back up? Thats a great price to add a ton of capacity to a system. Thanks.

The terminals look like the Amphenol style push-on connectors used on Ruixu Batteries.

Yes that should help with balancing
Nice battery, but the deal breaker for me would be the battery connection terminals, give me bolt on cables any day !!!
Agreed, but at this price I’m willing to still use them.. for now at least
get a victron bus bar
So where can I order samples for testing of this AOLITHIUM 51.2v 100ah Server Rack Lithium LiFePO4 Battery for less than $1,000?
Not as good of a deal as it was over black frlday... but still very close....

oh and AOLithium told me these units are not designed to handle being upright like that.. Not sure why unless the cells were not supported properly?

Do ypu know whats the size of the Surlok connector? Thanks
competition is good for us consumers, the EG4 indoor wallmount has recently become the better deal.... includes internal heaters ....shop around!

Can you recommend one? 48 volt
They are on sale now for about $1000 which seems crazy, but the connectors / cables still bother me.

Any success in getting these to communicate with eg4 batteries?
Still working well as pairs to a busbar?
Do these have a pre-charge resistor in them? If so, is the proper startup going to the breaker and then the power button? Thanks!
I think so, page 13 of the manual shows the schematic of the BMS and it includes a "Precharge Module".
I have the same batteries however the graphics on the display looks different. I wonder if I need to do a firmware update to these batteries?
you know i noticed that on some people's batteries the BMS looked different. not sure what the deal was. did you update yours?
No I didn’t I noticed that too I will try and update it
