IBS dual battery kits

Looking to add a second battery to your Tacoma? Sierra Expeditions carries the IBS Dual Battery Systems. This is a complete kit with everything you need to install into your Tacoma. $379.95 + Shipping



This kit includes:

• 200A Relay (12v Systems)
• In-cab monitor with flush mount (optional mounts available)
• Wire Harness
• 10' of 4g positive and negative cables
• All connectors needed to complete installation

After trying several different brands of dual battery kits, this is the one I personally use and recommend to those in the market looking for a dual battery kit. We have installed these kits on several Tacoma's and are very pleased with the results.

Here is my install (pre wiring shield):

I went with the IBS dual battery system with the option RBM (Relay Booster Module) to replace my problematic National Luna




Here you can see the control unit. It is slightly larger than the NL, but has all electronics in the cab, unlike the NL which has it mounted above the solenoid. This makes this unit much more water resistant than the NL kit.


The solenoid itself is much smaller in comparison and sound wise much quieter when linking or disconnecting the batteries. When I h ad the surepower solenoid it would trigger the glass break sensor on the alarm, as would the NL. This unit does not trigger the glass break sensor with the solenoid mounted directly to the firewall.


It's hard to tell here, but everything is sealed, keeping water and dust out.


The harness was a breeze to set up, simply 4 wires through the firewall and connect per the instructional diagram. In my case since I was installing the RBM, the diagram I had to follow was the one included in the RBM package.




Again fully sealed!!!


Controller mounted using a swivel base mount:


Under the hood, Still need to add wiring looms before too much driving.

 

Here is some pics of a Gen 2 install that we did in our shop a few weeks ago:

Aux Battery mount (relocated ABS):


Control Mount:

 

Nice placement for the control unit. How did you do it cut the existing and if so with what. it looks clean.

 

Hey Wil, Where did you install the second battery in the gen 2 Tacoma?

 

It is mounted with a slide-n-lock pad that is mounted to the console.

You can see the battery tray mounted on the passenger side fender, with the ABS slightly re-located in the pic below. Please note that if you mount this way you want the positive terminal towards the engine so if there ever was a chance of the mount failing it will not ground to the hood, in this case the battery was mounted so that the positive was towards the firewall, and the negative toward the grille to mitigate chances of arcing.

 

Awesome stuff man! i am looking to go duals soon

But i am a bit confused with your wiring diagram..your starter battery is still running your winch? is that what you wanted??

I don't really get why you would need the control box..


oh..and do you have a build thread?

 

You want to wire in the winch as close to the alternator as possible, when winching you use the Battery Monitor (controller) to link the two batteries plus you have the alternator as well.

The control box or battery monitor, allows you to monitor the batteries, link the batteries (self jump starting, winching, and other high load situations). The battery monitor also houses all the computer portion of the battery kit, thus keeping it out of the engine bay and in theory "high and dry".

not on this forum, I have one over on ExPo here: http://www.expeditionportal.com/forum/threads/728-Flyingwil-s-Taco-is-growing-up!

I keep missing the group buys on the other sites that we both frequent and wanted to know when the IBS group buy for TacomaWorld will go down. Thanks for the write up on the install and use.

 

this system is great by tha way! does everything auto so u dont have to touch anything! the only thing ive had to do is ive run my primary battery down too low a few times and had to manually link the batteries together but truck cranks right up! +1 for this setup

 

Wish I had this setup!

 

More info on the solar panel please

 

^^^This

And whats the relay booster module for?

 

subbed

 

I know this thread is old... I'm posting anyways.

The solar panel with regulator allows the Aux battery to charge independent of the engine running. (You can find quality solar panels from www.wholesalesolar.com with 20 year warrantys, and you can find solar regulators for under $100 on Amazon. The regulator is necessary for stopping the charge when the batteries are full.) But the way I understand the IBS system is that it does even more. From the sierraexpedition.com website:

The way I understand the above text is that, if the solar energy is more than enough to run the auxiliary load AND charge the Aux battery, then the two batteries are linked and the solar charge will charge the starter battery as well. This is a really nice feature if it works the way I understand it.

The IBS product looks like a really nice one. The price is a bit steep IMO.

 

i would love to have one

 

My National Luna set up in my 80 series draws down the battery voltage of both batteries if I don't drive it for a couple of weeks. Does the IBS system do this as well? Thanks

 

No, the system will turn its self off on the monitoring side. I went from a National Luna to the IBS about 3 years ago and haven't looked back since.

 

Wil, what is the additional parasitic load on your starting battery with your IDS Monitor? and why do you run your winch off of the starting battery instead of the aux (deep cycle) battery?

 

Thanks Wil. I found the specs on that and the NL kit draws 40ma and the IBS draws 1ma while parked. Nice to know that it will shut off as well if the battery gets low. Pretty sure the NL doesn't do that either.
