Thanks for the video. I have one of these sitting in my boat waiting to be hooked up over the xmass holiday. Excited to see how they perform although im going to keep it simple and only use a BVM-712 monitor instead of the Cerbo. I agree the charge/discharge specs for these batteries are insane for the price. with two in parallel they can output a constant 600 amps, 1800 for three seconds. These would probably start a diesel very quickly if the start bank goes down.
To further what others have said regerding the ethernet connection to the garmin, when you connect two devices to eachother with an ethernet cable, you need a crossover cable so the data ports are talking to the right conductor. When you connect two devices to an ethernet switch so they can talk to eachother, the swich does crossing over for you.
Makes sense. The Garmin unit in the video was actually defective. The ethernet port was dead. I had it warrantied out and when I got the replacement unit I just used a standard Victron RJ45 from the Cerbo GX ethernet port to the Garmin network port and everything worked instantly with out issues.
Great video. Trying to decide between 2 x 300ah non-Victron or a single 460ah Victron comm battery (space constraints). Looks like the shunt can do a lot of what the Victron comms would do. I have a shunt, do you think the batteries with Victron comms are a must have or nice to have? Thanks!
Basically Victron Comms use the BMS V2 communications protocol. And when hooked to a GX device and have DVCC enabled it allows the battery BMS to dictate all charge parameters and commands. No need to research parameters or Puekert factors and tail currents etc. The battery gets what the battery wants. But you can definitely save some money and accomplish a similar outcome by using a shunt and taking the time to set it up and tweak it in. I would opt for bluetooth in any battery though as a minimum.
@@mvintrigue-trawlerdiy1101 are the Epoch batteries have enough capability to communicate with victron system where when the battery is full and no longer wants charge to communicate to an external alternator regulator to stop sending charge? i.e maybe from Epoch battery to control Cerba GX to control a canbus enabled regulator such as the wakespeed WS500? or Epoch battery to victron smart battery protect to ignition switch on a non canbus enabled external regulator such as the Balmar MC-618? I'm thinkin of getting a Balmar XT170 or XT250 Marine Alternator
Did you try an eithernet crossover cable? If neither the Garmin or the Cerbo GX are Auto MDI-X you either need an ethernet switch/hub or a crossover cable.
I have the GMS10 Garmin hub in the boat. Another guy said it may work when run through the GMS 10. In the meantime I suppose I could buy a crossover cable. Just ordered one.
You used a splitter to connect the 2 batteries to the Cerbo. Do you have that part number. Epoch support told me that the current 300ah V2 couldn’t daisy chain. That there was an issue. Versions coming out in mid 2024 should be fixed. I’m looking to get a couple now and will go with a splitter like you had. Did you have any issues with using it?
Thats not daisy chaining. You can plug both right into the Cerbo and it will read both batts but they cycle between the two. Thats not ideal but it works. You can also just use one batt to send data to cerbo and let that single batt control everything and use the bluetooth app to check both batts are staying synced.
I dont know if there is an answer for that. I had the 300v2 and decided to step up to the 460 and sold the 300v2 to a buddy. Its preference since both are functional.
Yes, sir. And you can drain them all the way down to 5 or 10%. They are 90% usable. Also, these are advertised as 300ah, but they usually have a bit more. One has 323 ah and the other around 314. So somewhere between 630 and 640 ah. The price is $1199 each, but it's easy to find 10% off codes. Cold weather, internal heating, bluetooth, and more. Pretty good bargain.
Is the center RJ45 really NC (NOT CONNECTED)? When I ordered mine, the sticker on the battery on the website said RS485 | CAN | CAN, implying they can be daisy chained.
