The batteries used in Titan Solar Generator are NMC batteries, which are a different material composition from LiFePO4 battery, it’s not recommended to parallel a LiFePO4 battery with other ingredients batteries for long-term use, since the difference in voltage platform and internal resistance will affect battery life. The battery expansion port of Titan Solar Generator is not used for the external increase and expansion of battery capacity, but only for emergency charging when the external battery is dead. Also, if the voltage difference between the internal and external batteries is large, there may occur a large current in parallel connection, which may lead to battery protection. This expansion port is used in an emergency for connection with a 24V lead-acid battery or a 24V NMC battery. Because the 24V lead-acid battery is without built-in BMS, and it’s not affected by parallel connection. Further, the 24V NMC battery is the same as the battery used in Titan Solar Generator, so it can be used in parallel. However, the LiFePO4 battery is a different configuration, and there is built-in BMS to manage the battery, so it’s not recommended to use the expansion port in parallel with the LiFePO4 battery in an emergency.

Second this comment! 👊

Using any battery is a huge selling point for the Titan, IMO.

Sweet. Always good when Ben digs it👍

Thanks for your introduction,let me know about the battery, I think it has high Cost-effectiveness🧐

5:11 there will never be a spark with no path for current to flow. The other terminals are not connected, no current will flow, no spark.

Very cool!

Seems “Ampere Time” this brand is good, look forward to your subsequent use experience, I already want to buy it.

Thank you!

Excellent video. As new Titan owner, I'm still learning all I can about its capabilities. Can you tell me what cable you use to connect the external batteries to the Titan, and where you got them?

Here is a Quick Short about how we are utilizing the Titan! kzread.infoc57ALQ1nUhw?feature=share

question, could you also have charged the Ampere batteries up to match the Titan charge before connecting, or is it better to have the charges lower on both sides when connecting?

Have you heard when the Titan 2.0 will be available. It was last spring I heard.

You can use a battery with any solar generator as long as you stay within the solar charging parameters utilizing the solar port. The generator doesn't know the difference. I do this with my Bluetti, Ecoflow, ECT...

Could you please do this with 48 V 300 AH BATTERY SO WE CAN SEE THE POWER?

Questions-1) will the solar input or charger input to the Titan also charge the external batteries? 2) can 4 12 volt batteries be used 2 each in series and then the 24 volt combination in parallel? 3) can battery types be mixed or must all be identical?

Hey Thomas, great questions. 1. No, the Titan cannot have external batteries connected and use an additional charge controller. 2. Yes, you can use four 12v batteries to make a 24v battery bank to work with the Titan. But it would just be easier to get 24v batteries to begin with. Then you can add even more capacity since each battery is limited in how many batteries can be connected together. 3. They must be all Lithium based. So Lithium NMC or LiFePo4, mixing those two types are fine. No lead acid.

@@minutemanprep The solar input of the Titan will in fact charge external batteries if they are connected to either the Titan's 24 volt external battery port or the 24V charger ports. At least it does on my setup. The only difference is that if you connect an external 24V battery to the 24V charger ports you should not update the Titan's display screen Amp hour capacity to reflect the external battery's Ah capacity, because those ports are on the load side of the Titan's shunt. The screen should only be updated if you connect the external battery to the Titan's external battery port because that port is on the battery side of the Titan's shunt.

Good info Ben, I'm looking to add another battery to my Titan and this will def help. With the listed price that's a good deal, 2 of those are less than $800. If I were to get 4 of those for the Titan what would be your recommended way to connect them?

Nice video Ben. I have been using external batteries on my Titan for about a year now. I have a few comments; 1) When you put the external 12V batteries together in series, they need to be at the same state of charge before connecting them in series. Just checking the voltage of each battery does not ensure that they are at the same SOC. Both should be fully charged to 100% before connecting in series. 2) When calculating the Amp hour capacity of the combined battery with the Titan, you added 100 ah for each of the 12v batteries plus the Titan's 74 ah for a total of 274 ah. That is incorrect. Since the 12v batteries are connected in series to make 24v, the Ah for those two are still 100 Ah. The combined capacity of the whole setup with the Titan is 174 Ah. 3) LiFePo4 batteries have a slightly different voltage/SOC profile from the NMC batteries in the Titan. Because of that, there are times when the voltage gets too high for the LiFePo4 batteries (for my comfort range) if the Titan is charged to 100%. I don't like pushing my LiFePo4 batteries past 28.4 V. The standard Titan battery goes up to 29.2 V. Just something to keep an eye on.

Bruce, would you recommend buying two 12v ampere time batteries to put in parallel to add to the Titan, or just buy another Titan battery? I see your concern for the ampere time batteries being charged beyond 28.4v. It seems like a valid question since two of the 100 ah ampere time 12v batteries can be purchased at $329 a piece compared to the $1300 Titan battery. I currently have 3 batteries(all titan batteries) on my Titan system and wanted to add more battery storage. I also know the Titan battery fits perfectly with my current system where the ampere batteries would take up more space and I'd have to pay more attention to the voltage. Any comments for an old guy trying to survive who wants to increase battery storage? Thanks

@@rameylewis7730 Whether to use LiFePo4 external batteries is a tradeoff that can only be determined by your specific use case. If size, convenience, and form factor are your major constraints, then additional Titan batteries might be a better option. If budget is the main constraint, then external LiFePo4 batteries are a better bang for the buck, but the form factor and operational considerations are a bit messier. Let me explain: As far as putting a 24V LiFePo4 battery in parallel with the Titan, it is okay to do, but you'll sacrifice a bit of top end capacity of the Titan's batteries, since they are NMC chemistry and need to be charged slightly higher than LiFePo4 to reach 100% SOC. I don't like my 8s LiFePo4 176 Ah battery to go above 28.4V, which is mid 90s% SOC on my Titan batteries(2x74 Ah). This means I have to manually manage the solar inputs on the Titan, since they will charge up to 29.2-29.4V. That's okay for my application in an RV, but I have to pay attention to it. I have a BMS on the LiFePo4 set to cut it off if necessary at 28.8V, but I don't like using the BMS for normal operations like that. The other thing that I have noticed is that the NMC and LiFePo4 batteries discharge unevenly at various overall states of charge since their SOC/voltage profiles are different. At higher overall SOC's, the Titan battery provides a higher percentage of the load. At mid to lower overall SOCs, the LiFePo4 battery provides a higher percentage of the load. Make sure your external cabling is sized to handle that. For my use case I have found that #6 AWG seems to work okay, but your usage situation might be different.

Couldn't connect lead acid or non proprietary batteries so ordered Inergy Flex batteries..

I also went with the extra battery and cable for my Kodiak. Be aware that my battery needed a firmware update to work properly with my Kodiak.

What happens when the solar charges the LiFePo4 and the NMC up to 29.2 volts and the sun goes down overnight then the LiFePo4 voltage settles down to 26 volts but the NMC stays at its 29.2, now you have to unhook the LiFePo4 and run the NMC down to 26 volts or within the .5 volt range of the NMC battery every day, what a pain in the ass. I just wish I could buy a NMC battery to plug into the expansion port but nobody makes them in 24 volt and 1400.00 for another Titan battery is too much for 2000 watt hours.
