P1000 Dual battery

was wondering if you use a lithium battery and agm battery which one should you use as main battery. True am recommends agm as main and lithium as second battery.

I wonder why they recommend that.

I chose lithium as the primary choice because many winch manufacturers do not recommend a lithium battery.
Therefore, I wanted my winch to be on the nonlithium, so the lithim became the primary.
I chose the ATX12. I have the 20 in my Talon.

WARNING - Make sure you get the lithium version of the isolator, or you will kill both batteries.

Welcome from Michigan

First post since joining 4yrs ago👏🏻
All good.
Tell us, what Rig do you have?

What @Hondasxs warned. ☝️☝️☝️☝️
Mixing lithium and agm needs special treatment.
Best.

2016 1000 5D. I questioned using lithium for winch, said his setup was using lithium for winch with no problems. What special treatment would I need??

 

[Hondasxs]

You will need to research it as I don't know enough to say.
But I read the discharge rate is not sufficient for winching from a Lithium.
Meaning even though it has the power to winch, it can't push enough current to the winch for optimal pull.

Using the LiFePO4 for Aux makes a lot of sense for the following reasons. The lithium battery has much lower internal resistance than the Pb battery (that's lead), so it can belt out the high current the winch needs for a significant period. The lithium can alos be discharged almost completely with no damage, (though it should not be left discharged, of course), while the lead-acid should generally not be discharged below 50%. This makes the lithium battery particularly appealing for Aux use.

The starter (lead acid) battery should be rated in CCA (cold cranking amps), it will have thin plates to get more plate area, this allows fro the high current needed to crank the engine. This battery is NOT well suited for deep discharge, it's not made for that. A lead acid that IS made for that would not be rated in CCA, but rather in amp-hour capacity, like a lead acid battery sold for running an electric trolling motoer etc. This Pb battery will have much thicker plates and fewer off them, for the same physical size - this allows the battery to be deeply discharged with less damage (though still not as good as that lithium battery.

Note that a Lithium battery and lead acid require a special version of the Tur isolator, as the batteries require different treatment to be "happy" due to differences in charging voltage, fully charged voltage, internal resistance etc.

In the above, I've used the term lithium. What I'm really referring to is a lithium ferrous phosphate (LiFePO4), as that chemistry allows the lithium battery to be much safer that the lithium-ion battery. Much less likely to cause a fire, with a bit less performance than the lithium-ion type.

My thoughts exactly. Been using lithium batteries in a lot of different applications for almost 20 years. I would use the LiFePO4 for the aux battery. You are correct it is different than the standard LIPO.I think people see lithium and think they are all the same

THanks for all the input

Sweet! Got any pics? Rule #4 POIDH

Did u have all the 16’ recalls and one campaign done?

I run AGM’s for both. 5 years so far and no starting problems even with 6 weeks between rides a few times.

No need for me, no crazy stereo or super sucking electrical accessories, keep tube in truckle and load test evert time I load it
