Very interesting Jono, hope you and Molly and all well and have a great Christmas!

[@gonenc85]

Why didn't you do the high temperature test this time ?

[@peterbabu936]

I got charger in AH, baterries in AH, changer in VA, and solar in W. Maybe is time for 1 unit? I recommend J.

[@VictronEnergyBV]

All items have a wattage rating. There are a certain amount of Watt Hours in a battery, a charger will give a certain amount of watts.

Victron, your stuff is top notch but these price points are pretty bad considering there are many other batteries out there with built in battery heating via charge incoming current and all of the same safeties.

[@UKsystems]

but they are not reputable for saftey

[@bartoski-ag]

so if i wire 4 smart batteries in series i dont need to add on the 3 balancers anymore?

It would be great if you put your roadshow that you just completed onto video!

Hello, thank you so much for this video. However, I am missing an important piece of information regarding use at low temperatures. We had cold temperatures last week and the battery stopped supplying 12V power at about +5 °C degrees. No lights or USB working in my RV. If I understand it correctly, it works as designed if charging stops below +5 °C, but consumption should still possible down to -20 °C degrees or untill "Discharge cut-off voltage“. But nothing works below +5 °C degrees and the "Temp or OVP" LED goes red below -3 °C degrees. Something wrong with my BMS settings? Please help and advice.

[@VictronEnergyBV]

Make sure your allow to charge and allow to discharge wiring isn’t the wrong way around.

[@kamilome]

@@VictronEnergyBV worked. Thanks a lot. To cables on small BMS have been swapped.

Hi, I want to set up smart solar 250/60 with "regular" lifepo4 battery. This battey is equipped with a BMS, and it can probably destroy an smart solar regulator What happend if BMS cut off the power and it cause lack of pawer for smart solar regulator? How should I protect smart solar regulator? Best Regards, Pawel

Schitterend ! Zoals gewoonlijk !

Dank u :-)

Kunnen jullie eens een simpel en duidelijk filmpje maken voor een(bv 12v -200ah) installatie in camper busje

[@SirHackaL0t.]

Do you make lithium batteries that would fit APC UPS’s?

[@VictronEnergyBV]

Hi Clive, you will need to look at the data sheets to see the sizes :-)

[@UKsystems]

you could just use a multiplus

[@bill2292]

Also, what is the difference in the output of rigid and flexible solar panels.

[@VictronEnergyBV]

That is a bit of a 'how long is a piece of string' question :-). The hotter a panel gets the more inefficient it is.

[@vandestiny96]

can I ask you a question? when I turn on my 1000watt induction plate the battery voltage drops from 13.30V to 12.40 volts without any other loads on , is this normal or is it too low? thanks

[@ImDembe]

How long and how thick cables? That's a pretty hefty load to pump out at 12v.

Hi. I have two Smart Lithium 200Ah connected in parallel managed by a Lynx BMS in my van. I can confirm your tests, being here in Sweden, the batteries have minus C degrees and allow discharging but not charging. As soon as I start the car and my buckboost sends charge current, the Lynx disconnects and separates the batteries from the onboard system. What is annoying me though is that the calibration of the two batteries is not equal. I have observed up to 6C difference between the two batteries and that is really frustrating that one battery alone would allow charging but the system has to wait for the other to warm up as well… why is that and is this a product issue to communicate to my supplier or you at VE?

[@VictronEnergyBV]

Hey there Ingo, The board that takes the temperature is on the top of the battery area. it's the same PCB board that balances the cells. From what you have explained I'd say one battery is in a colder environment than the other. Maybe closer to a side wall or it gets less air flow from heating? Have you taken them out and stood them next to each other in a heated room for example to check?

[@ingopfeiffer5642]

@@VictronEnergyBV thx for reply. - when I last summer unpacked the batteries and checked Bluetooth Victron Connect for the first time they had been in my garage for several days on the same shelf -> already then showing a difference of 2C: 17 & 19 C respectively. - now, in my car (unheated on the driveway) they are located in front and behind the passenger wheel well, approx 1,2m apart from each other. I am pretty sure there is no delta in ambient temp after the car being unused for several days. Still, they show different temps; higher delta the colder the surrounding. - when used, eg after longer time charging, the temp shows equal temp, but only when reaching mid-20 to 30C Can we maybe continue this discussion in your direct support channel (or Victron community) to discuss and incl possibility of attaching pictures?

[@rcchenhk]

How to fix the cell 1 & 2, any balancing circuit inside the battery?

[@VictronEnergyBV]

Hi Robert, yes under heavy load cells of all lithiums can get unbalanced. This battery has built in cell balancing yes.

[@kevgermany]

Interesting. You said these batteries are self balancing. Why are the cells going out of balance?

[@VictronEnergyBV]

Hello, under heavy load cells of all lithium cell can get unbalanced. This battery has built in cell balancing so it'll soon sort itself out. We had to put it under extreme tests to show the unbalance for the video.

welke kabel heb ik nodig om te comuniceren tussen de multiplus 2 en de cerbo gx is dit een type a of b kabel ?

Good evening, I was asking for information, can I install my Victron Smart Lithium 300A lying down? Thank you, I look forward to your feedback. Nizzoli Pier Giorgio from Italy

[@VictronEnergyBV]

Hi there, In the manual it states the batteries must be installed upright I'm afraid.

[@evansmacharia3927]

How much are these batteries and where can one get them? I would like to get a price quote

@@VictronEnergyBV I have an MPPT 100/20 I'm having trouble getting support for. The dealer can't seem to help me figure out why it connects to my phone via bluetooth but the VictronConnect App can't see the device it never shows up in the app. I went to your website and couldn't find any support offerings at all other than the manual and a referral to my sales manager or dealer.
