You can isolate the break away battery from the auxiliary battery using the Battery Isolation Solenoid # PK5231201. The auxiliary power supply that is needed on this solenoid can be the running lights of your trailer. That way, when your trailer is connected, you can charge the break away and the auxiliary trailer battery, but when not connected the break away battery will not be drained by the auxiliary trailer battery. So the 12V comes into the trailer and runs to the aux trailer battery... view full answer...
The Battery Life Solar Battery Charger and Maintainer part 329-BLSOLAR5 is a great option for a smaller battery but won't do much at all for your two Interstate SRM-24 batteries.The most important aspect in choosing the correct battery charger is Ah (amp hours). The Battery Life Solar Battery Charger and Maintainer is rated for use on batteries between 1.2 - 20Ah (amp hours). The Interstate SRM-24 batteries you have are each rated at 84Ah each which means this battery charger will not be... view full answer...
A charger such as # 20011 will not be able to charge up a regular battery, only small breakaway batteries. The issue is that the wiring on the trailer and vehicle is not large enough and the alternator is not strong enough (on most vehicles) to push back the amperage required to charge up a battery. At best it can only maintain the charge level of the battery.
Also, you will want to disconnect the breakaway battery from the larger battery. Otherwise it will just drain it and also shorten... view full answer...
For you application the Deka Battery Isolator # DW08770 would be a solid choice and a great solution. It will allow you to charge your auxiliary batteries from your alternator while preventing the aux batteries from draining the main battery when the vehicle is off. It also enhances the alternator charge to make it ideal for charging a battery. view full answer...
We can help. There are two different ways to wire up batteries and battery banks to either keep the voltage the same or double it.
If two batteries are wired in parallel, the positive terminals of each battery will be connected together, as will the negative terminals. Assuming both batteries are 12 volt, you'll have a 12 volt output but there will be more capacity.
If the batteries are wired in series, the positive terminal of one battery will be connected to the negative terminal of... view full answer...
You can use a standard lead acid battery to charge an AGM battery if you have the correct battery charger as not all will allow for this. I cannot speak of the voltage sensing relay that you are referring to but I can confirm that the Redarc In-Vehicle BCDC Battery Charger will allow you to charge an AGM battery using a standard lead acid battery. This charger is offered in two different capacities, part # 331-BCDC1225D for 75-200 Ah batteries and part # 331-BCDC1240D for 200+ Ah batteries.

As long as you get the voltages to match up correctly you can add a 12 volt battery to a battery bank with the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box # TLA7740.
The key is knowing the difference between running the batteries in series vs. in parallel. Your 6 volt batteries are in series currently so you'd need to add your 12 volt battery to them in parallel so that the voltages all match.
So the main negative post of the 6 volt battery that you run to your trailer... view full answer...
For a larger alternator like what you have we have the Redarc Smart Start Battery Isolator # 331-SBI212 which is rated for up to 200 amps.
With this battery isolator, you can transfer power from your start battery to an auxiliary battery without draining your start battery. As long as your vehicle is on and the alternator is supplying power to the start battery, the isolator will transfer some of that power to your auxiliary battery. When your vehicle is shut off, the isolator will separate... view full answer...
The Bright Way Deep Cycle RV or Marine Battery # BRW94FR will provide you with a 100-amp hour battery and is a deep-cycle AGM battery that provides long-lasting, dependable power for your trailer.
The charge that you get from your 7-way will only be enough to trickle charge your battery. Essentially it will maintain the battery if the battery is not being used for other things, it will not charge a depleted battery. In order to actually charge the battery you will need to use the Redarc... view full answer...
Maintaining the battery with the charger part # CTEK56353 would be a great option to allow you to not have to keep replacing batteries.
This will keep the battery topped off and in good shape. view full answer...
Car batteries and motorcycle batteries have much different amp hour ratings and should be charged separately. I recommend the CTEK charger # CTEK56353. I own this battery charger as do several of my co-workers and it works fantastic for everything from 12 volt lawn mower batteries, motorcycle batteries, to car and truck batteries.
I have included a link to a video review of this charger and a link to our FAQ article on battery chargers for you.

The inner dimensions of the Commercial Grade Battery Box for Group 4D Batteries # 329-HM408 are 21-3/16" long x 9-5/8" wide x 11-1/8" tall. Based on the dimensions of your LifePo4 batteries you'd easily be able to fit two in this box. view full answer...
There are two ways to wire up 6 volt batteries depending on what output voltage you are looking for.
If two batteries are wired in parallel, the positive terminals of each battery will be connected together, as will the negative terminals. Assuming both batteries are 6 volt, you'll have a 6 volt output but there will be more capacity.
If the batteries are wired in series, the positive terminal of one battery will be connected to the negative terminal of the other. This would double the... view full answer...
When hooking up both your deep cycle 12V battery and breakaway battery to a solar panel controller you shouldn't need to add a resistor in line between the two batteries. When using a controller that features dual battery profiles like the Go Power # 34276119 there won't be any concern with the breakaway battery draining.
A 100 watt panel like the Overlander Charging Kit # 34272635, which includes the above-mentioned controller, should be sufficient to keep both batteries charged according... view full answer...
If the batteries are wired in series, the positive terminal of one battery will be connected to the negative terminal of the other. This would double the output of the batteries, assuming each battery is a 6 volt, wiring the batteries in series would provide 12 volts of output.

You don't want to mix lithium and lead acid batteries in a battery bank. The reason being that the lithium batteries have a higher resting voltage than the lead acid batteries so the lithium battery is going to be drained constantly by the lower voltage of the lead acid battery. Your best bet would be to go with all lithium like the # PS44FR that you referenced. view full answer...
Your best option for charging the battery bank on your enclosed trailer from your vehicle battery is to use an in-vehicle, BCDC battery charger. The correct option depends on the size of your battery bank.
- Redarc In-Vehicle BCDC Battery Charger # RED96FR (Ideal for smaller battery banks rated less than 75 amp-hours)
- Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D (Ideal for battery banks rated between 75 and 200 amp-hours)

I spoke with my contact at NOCO regarding the use of the GEN4 Genius On-Board Battery Charger # 329-GEN4 for your application. She stated that this will work great to charge your two 12V batteries and four 6V batteries.
What you will need to do is pair up the four 6V batteries and wire each of the two pairs in series so they have a 12V output (see attached image). Once you do this you will hook up the terminal ends of the GEN4 as follows:
- Bank 1 to the first 12V battery
- Bank 2 to... view full answer...
The battery that you use for a break away system needs to be able to power the trailer brakes on full for 15 minutes. A 12 volt battery rated for 5 amp hours would work but if you had 3 axles each with brakes you would benefit more from a 9 amp hour battery. Even a 12 volt car battery could be used but a battery this large would not charge up through the 12 volt circuit coming through the trailer connector.
The batteries only that we carry, # HM20008 and # TK2023 are both rated for 5 amp... view full answer...
A fully discharged battery might require a little extra assistance in order for the Tekonsha charger # 2024-07 to take effect. Bad things can happen to batteries once they are totally dead. We do have some pretty substantial battery chargers that can revitalize a battery, like # CTEK56353. But even this charger cannot save a battery if it is too far gone. view full answer...
