JBD bms are the best. Built 3 12v batteries with them using an sunfunkits branded jbd and just recently tried a 8s version. JBD + active balancer is the most reliable combo and with the sfk buttons you can set it to only turn on the balancer when the battery is near full. There app lets you see...

Yes its worth it, I'm doing a small test 24v victron system myself and the cerbo comms are great IMO. If you didn't need comms why go with a victron at all. I'm using a sfk 24v kit 150ah 24 with comms. In regards to epoch only the 460 supports multiple batteries, the other essentials brand...

Very strange, but I will say I did replace the BMS from the Battle Born battery to a JBD BMS and was able to revive my bb100 battery. You could replace the BMS with a JBD 200 bms perhaps, it has a bluetooth you can unplug. sun fun kits uses these bms in there batteries but they have switch that...

I got there 275SE battery recently (not listed on there site but they will sell to you if you contact them) its a non heated battery with a 150 amp bms but still has cold temp protection and bluetooth as well as the comms to victron: It was $1,040 shipped and came with the data port and the non...

warranties on batteries is a myth IMO and epoch is run by 18650 who have really bad warranties and customer support so good luck to you. The epoch batteries are actually made by a company called RoyPow and they are owned by the EVE Cell Manufacturer so I would be surprised that you would need...

Before we see who is right or not, lets wait for the OP to do his investigation and then we can decide. For those wondering currentconnected carries CALB with test reports but they are very expensive.

The SOK is a great deal for a heated battery as its only $1000 shipped from there site and has heating, just not good if you are using it on a boat because its metal: https://www.us.sokbattery.com/product-page/12v-280ah-lithium-battery-built-in-heater-and-bluetooth The SFK is smaller in size...

I got my tracking number for my 48 pallet of 304 cells last Friday, its coming from Long Beach, CA to Arkansas and is supposed to arrive on the 19th. I ordered during the black Friday sale. The carrier is Saia Freight Lines. As for time so far its been about 70 days. If it delivers on Monday...

Well they have good prices but they are cutting corners everywhere, I guess if you wanted the cheapest possible go with them but expect same level of service as an aliexpress seller. From what I understand they are no longer sending test reports even with grade A cells. BTW you have some...

The only 150a cells that fit the SFK kits are the rept cells which I don't think they are selling, that or the eve 105, They are using 8 cells. I think you would end up doing a good bit of diy-ing to get there kits to work. They are good but like you said only for the 270-304 cells and maybe...

You only have 7 days to return a DOA product?

I am part of the JBD gang as well.

No they were grade B, but 18650batterstore said they are supposed to pull full capacity. They did not honor this, I ended up not even using these 4 cells and in the long run I probably saved a headache and now just get grade A cells.

I would recommend you look at the SOK 280 battery which has free shipping and is heated 280: https://www.us.sokbattery.com/product-page/12v-280ah-lithium-battery-built-in-heater-and-bluetooth they are $1000.00 with free shipping There are some advantages: 1) Its is fully serviceable including...
