Nothing else to say, do not buy these (rebranded) battery chargers from Amazon. Worked fine (albeit under the advertised amperage) for the few times I used it over a 1 year span. Plugged it in today and it caught fire and shot smoke everywhere. Lesson learned.

Hey Lt.Dan, thanks for sharing this! Question: Do you happen to remember where you purchased the VIP BMS with Bluetooth? I have four batteries with this BMS and I'm trying to hunt down more information on the unit. Thanks!

Ok I opened up the battery with the Bluetooth problem (not broadcasting to connect to with app) I unplugged the Bluetooth module from the BMS and plugged it back in, and it worked! I think it may have gone wonky because this battery fully discharged from sitting in a warehouse for over a year...

Bluetooth on one of my 4 batteries isn't working, trying to figure out how to reset it or if it's broken. Something I've noticed is that it's important to check the settings on these (via the Bluetooth app), as all they have different settings. 2 of my batteries were set at "Full...

Pretty close, but not 100%

Don't even know how relevant this is but: attached

Circling back to update this thread so anyone googling may stumble across, save some time, and maybe contribute some stuff I don't know. Something tells me they will not be producing batteries under this name much longer given their dwindling offerings, but I could be wrong. -Looks like these...

Thanks for the response, lucky me they had 2 left in used stock so I snatched em at a discount. Did some digging and it seems these batteries use VIP BMS with Bluetooth (and low temp protection). If anyone sees this in the future and knows anything about these BMS, please reply and dump whatever...

For my Himassi batteries on ee-bms it's 666666 for details and 888888 for settings.

Mmm perhaps I can go into a series-parallel safely... 24v 400ah

I made the mistake early last year of not forward thinking on scaling my storage. I bought 2 chinese batteries (Himassi 12v 200ah 100a low temp bluetooth) batteries from amazon, strung them into series for 24v, along with the a 24v SCC and 24v pure sine inverter. The batteries have been great...

Maybe spoke to soon, after I made the last post I changed my boost (absorb) and float to 27.6 and max out the boost (absorb) time. Hoping the max boost (absorb) time of 3 hours on the BN is enough to keep my cells balanced, still testing. But no more over voltage spikes/inverter resets as of now!

Well it's been months and no matter the settings I choose on the charge controller I still have the same problem. I've resulted to using a UPS to keep the 24/7 stuff running (so it doesn't die when the voltage spikes and the inverter restarts). Should I just try a controller that "officially"...

My buddy shared the following link: https://community.victronenergy.com/questions/125942/voltage-spikes-with-mppt-near-absorbtion-dc-to-dc.html Adding to my last post, this is deff looking like a "your results may vary" situation depending on the hardware involved. I'm going to try setting my...

Yea, at this point - as mentioned below, I think it has to do with the Lifepo4 charge settings vs the BMS & inverter itself. Not so much the brand, but testing still underway. This sounds accurate in terms of what is unfolding. Looks like it's gonna be a game of "how high can I set the Boost...

It certainly might, I've been talking to my buddy about it as well who just-so-happens to be having the same problem with his new Lifepo4 setup (totally different components than me however). I've sent him this thread so hopefully some solution comes up that doesn't require spending. After some...

Howdy Ya'll, In my quest over the last couple months to find the cheapest yet "trustworthy" storage for my solar office project, I found HiMASSi on Amazon (US). Going to keep this short as at this point these clones are running mostly together. That said, They have 100ah+ LifePo4 batteries with...

Think this is it, the video posted below indicates this as well and this is my exact issue. Thank you for sharing! This is exactly what I'm seeing, however my settings are literally the 24v equivelant of his settings in the video (which are 12v). I guess I'll keep trying to knock the voltage of...

Thanks, I'll double check this but the timing of the "restarts" is just too... perfect with the SCC hitting Boost, I literally watch the voltage creep up to my Boost setting on the Inverter's display, and it freaks out and restarts/browns-out right when the voltage is hit and my SCC stops PV...

Looking for some guidance as I really don't know what's going on here. Setup: SCC: Epever Tracer 4215BN Storage: 24v 200ah Lifepo4 with 100a BMS Inverter: 2000w Pure Sine Cables: All sized correctly (I know this will be asked) My SCC and Inverter are connected directly to the battery terminals...
