question

Just to make sure: will the bms cut of charging when below 5 degrees C?

Also, does the battery need a minimum voltage to stay balanced?

'end of discharge voltage' 10V I assume that's where the bms cuts out, but over time, a little imbalance in the cell capacity will make the battery cut-out at a higher voltage, so you might want to make that 11V (2.75V per cell, battery is really empty than) as a target 'discharge' voltage.

Looks like a great new product!

Is there any way to check the internal state of charge, cell status, or temperature?

Will this be a drop in replacement for my starter battery on my car? I take it glamping and then I wouldnt have to bring an extra battery for the amenities....

@Peter Polz asked: "Especially for me i am interessted in how allow to discharge and charge works in case of only one connection to terminal? Will the mechanism completly block in case of error that customers have to reset something or is there internally an diode mechanism which can handle both direction seperatly controlled with one terminal? "

Answer: No, the mechanism will not lock out requiring a user intervention:

• Charging remains possible after end of discharge shutdown
• In case of overvoltage the mechanism will unblock after ending the overvoltage, similar for overtemperature or charge/discharge overload.

A few questions:

* What is the estimated lifetime of system - defined as say capacity >= 80% nominal, if it is used in a permanent float configuration (i.e. rarely invoked UPS type scenario)

* What is the optimal absorption frequency to maximise pack life / capacity?

* When will this hit Australia?

you are saying 2500 at 80% DOC then what stuffed or whats its status at that point

as a example question

after that 2500 has it still got 80% of its original capacity left

then 5000 cycles and 70% of its original capacity left

then 10000 cycles and 60% of its original capacity left

Would it be advisable to make it very clear that ie in boats these may not be advisable to use as there output max current is only 100amps for 10s . Especially for the higher A/H versions as they may say O' I have a 200 a/h battery and they will think it can put 200 amps out

The battery itsself as per picture currently has the charge limit it should also have the max draw limit as well

ie a multi 12v 3000/120 inverter charger would stuff one of these and even two /3 batteries in parallel we could/would still exceed there limits.

I would be making it very very clear in the manuals that these battery's have low max current output limitations

And Also

its NOT clear at all that a inbuilt cutoff is inside the battery and how it restarts for charging in a low voltage cutoff situation.

and once every few months it should be charged to 14.2 volts for say 1hr for the balancing to work

Just my thoughts

Is this Lithium SuperPack (for example the 100Ah) suitable for a small fiber-glass boat?

- the manual states that Maximum humidity should be 95%?

- is there a danger of the battery catching on fire and how can this risk be minimized?

- is it good to charge this battery with solar panels?

I've taken note of comments and now published a blog about these batteries https://www.victronenergy.com/blog/2019/02/26/lithium-superpack-batteries-an-all-in-one-solution/

Hello,

My supplier sold me a superpack battery and a Cyrix-li-ct to connect both start battery (lead) and leisure battery (super pack) to the engine alternator.
I read on another post that Cyrix-li-ct need a charge disconnect signal “+” on the pin 85 coming from the BMS. As there is no output from the internal BMS of the superpack, I am in trouble.

What is the recommended connection scheme to be able to charge both lead start battery and superpack leisure batty with one single alternator? Is it possible to apply a tension on the 85 pin of the Cyrix to force the Cyrix connection? What is the tension to be applied then?

Thanks,

Cyril

What type of cells does it have inside?

In which country are Victron Super Pack batteries manufactured and are they licensed for air freight?

I see the lack of series operation as a big drawback. I take it this is due to the voltage rating of the disconnect system and lack of external communications to the internal bms? Also having the continuous rating at C/2 is a bit marginal for some applications. Perhaps the bms could use a Bluetooth system to communicate and synchronise with other batteries and external bms display..?

Just a question. Can this lithium superpack be used as a start battery for a 50HP engine?

Was excited till I saw no serial connections and also no 48V offering so that rules out a HUGE audience, me included.
