I will keep the review as less emotional as possible and try to stick to the facts .
After seeing the good reviews of the SOK 48V battery, i ordered mine from https://www.europe.sokbattery.com/, before i order i asked 2 questions 1 was if the battery is supported by victron and the shipping time.
The answer to the victron was yes, and shipping time should have been 1 month.
I proceeded with the order, and shipping time was 2 months and a bit more, which made the beginning of the bad experience.
On arrival and after connecting the battery, I realized that it wasn't supported by CerboGx, and on contact with the manufacturer, I was redirected to the "Current Connected" article about it.
Since that was something to be fixed, and though it made the experience salty, there was a way to bypass the issue, so i kept using the battery and waited for the Victron update (which, 6 months after, hasn't been released on the stable version yet).
Meanwhile, while charging, I noticed that the battery wouldn't charge over 55 volts and also will trigger the High voltage alarm and disconnect related article can be found here: https://diysolarforum.com/threads/sok-48v-100-a-wont-balance-the-cells.53139/page-3#post-714801
Current connected did jump in and did their best to help me solve the issue "FOR FREE" even though i was not even their client (remember i bought directly from SOK).
The current connected arranged so a comm wire is sent to me so i can modify some parameters in the BMS and achieve cell balance and full capacity of the battery, the cable had to be sent twice and current Connected was always fast to reply to my emails.
Now while playing around with the battery screen i noticed that my battery had a cell that was always super high, so i decided to contact SOK about the issue and ask for a refund, replacement, or for them to pay for the repair needed.
In return (and if someone i can share screens of the emails) SOK official support never asked to run any troubleshooting or sent them cells voltages the answers i got and i quote were:
"no one has complained so far and we sold a thousand batteries"
"You have setup the CrboGX wrong"
"No warranty"
As you understand keeping in mind that cerboGX get the charge voltage directly with comms from the BMS there was nothing wrong with my setup, on my frustration i decided to share my experience on the SOK Facebook page, after some more arguments i received no replacement for this cell or battery.
In the end after posting that SOK doesn't honor warranty I even got kicked out of the group.
Now after Replacing that cell on my own COST the battery finally is balanced though it still gives a high voltage warning alarm at 57.5V (atleast it doesnt cut off)
Those are my positive (Thanks to the current connected and Negative thanks to SOK ) experiences, would i buy i again ? NO
a product in my opinion is as good as the people standing behind it, if a company denies your warranty claim without even putting you through troubleshooting they are shady in the least.
