Oh geeze these came down in price a lot...

Last price I saw was 32k

Bump

Just a suggestion,... why not add this battery to your existing house bank?

Sadly with the price of new batteries right now you will not even get half of that R32K back.

Hmmmm...

"Ultra-reliable Lithium Iron Phosphate Technology. Power output = 5.2kW (continuous). Performance cycle life > 6000 cycles. Can be discharged to 100% DoD. Now with a 10 year warranty. Note that Blue Nova BP & DU batteries cannot be mixed"

BP = Backup Pack

DU = Daily use, not sure about mixing this with whatever @Adagio has in the house now... also interesting is the > 6000 cycles, assuming as a BP with, say once a week a partial discharge (lets call it a 100% discharge, once a week) would that imply 6000 weeks of life, esxpected? Aka 115 and then some years?

Pondering it. But the two batteries have different BMSes and cell counts.

If theres no bites by the end of the week, I'll just get 2 more of these and call it a day.

I'm parraleling inverters and need a pack with a higher C

What current batteries have you got and what is the cell number for them as well as the BNova?

The interesting point on the Bluenova BM is under the features as per the links posted earlier the load can be 100A continuously. Yet in the specs it can only be discharged at 100A for 30min.?

Shoto 50Ah 14 cell

And the bluenova is a 15 cell 100AH

Hey Scorp! Long time!

I would stand to be corrected but Shoto SDA10-4850 48 V 50 Ah is 16 cells with a nominal voltage of 51.2v. Same with the BlueNova(16cell) so it would be safe to parallel them you just won't be able to use bms communication.

The Manufacturer specs stating 100A for 30 minutes is wise and deliberate. I will never discharge a 1C battery at 1C as the heat generated internally will shorten the battery lifespan. The sign to increace your battery bank capacity is when you discharge at or above 0.5C. 0.25C discharge is always my preference and target.

Hey Scorp! Long time!

Based on the reply that both batteries are 16 cells I would be happy to use the BN in parallel and just disable the comms and use voltage control. The negative of not having a very accurate SOC is a minor measured against the increased capacity gain and no further cost to you.

Should you decide to parallel the 2 above-mentioned packs Ensure before you do the parallel connection that both batteries was charged individually to 100%Soc. Also check the terminal voltage before connecting in parallel and should not have more the 0.5v diffrence. Then pre- charge the inverter and connect the paralleled bank and charge both together to 100%Soc.

I am sorry for the seller. But please stay away from blue nova. Over charge issues. Cell death, bms failures. https://www.facebook.com/share/p/1EfpoteQjc/
