2024 wolf pup battery wire gauge size?

[doctor J]

Does anyone know what the battery wire gauge is on a 2024 wolf pup, trying to calculate which fuse i would need for an lifepo4 battery upgrade?

If this is just a battery swap, the resettable breaker on the frame should handle it. I will guess #8AWG for wire.

Unless you increase the load on the wire by adding something like a inverter the wire will be fine

Add more load to the battery is not same as adding better battery.

Battery only sends the amps that is requested by the “load”

Standard 12v loads will max out at under 30 amps …. If battery fails and somehow sends a huge surge the small standard breaker will trip and protect the wire

If you add inverter you will probably be adding new wires from battery to inverter without changing the existing wires for standard loads

When you do the swap
Get good battery monitor either battery with Bluetooth or shunt

If you don’t see good charging from converter look first at the negative to frame connections…. Fixing any poor connection is usually free and can greatly increase charging performance

There are possibly two negative to frames connections
One on battery cable
Other one from converter to frame

Moved thread from the Tech and Repair section to the TT/5th Wheel section's Cherokee sub-forum since the OP is asking for model-specific information on a Cherokee product.

what i am doing is getting a Eco Worthy, blue tooth,12v 150ah lifepo4 with a 120amp bms, the cheaper batteries sometimes dont have the most reliable overcurrent protection, i just want to put a MRBF fuse on its positive terminal to protect the wiring between it and anything else i might add in the future. So far it appears i would need about a 125 to 150 amp version.

Keep in mind that the fuse is there to protect the wire. I think #8AWG will get pretty hot before blowing a 150A fuse. I like MBRF on the post, that's what I have on the three of mine.

Sounds right, so 125a would be better

NO

Why would battery cause more amps to be sent through wire?
A faulty battery or a short might send higher current BUT the smaller standard fuse is what you want to protect your wiring and tv


A large lead acid can discharge a bunch of amps very quickly but no one says increases the fuse …. Those hybrid marine ones can discharge hundreds of amps for quite a few seconds for starting motors

Unless you plan to use 150amps from any type of battery ……..there is no need to add more fuse cabability

A external fuse on a lifepo4 battery will not protect the battery if there is a bad internal fault
adding a larger fuse to a standard wire is like using a rusty nail because your fuse keeps blowing….. not the best idea….

Leave the fuses as is unless you intend to use more power or add bus bars to combine loads into a single circuit
Then you will need to allow for the new load amps AND distance to work out wire size and then add correct sized fuse for that circuit

If you are going lithium, you may need to change the configuration of your charge controller. The 2025 Wolf Pup comes with a Rich PWM 30 amp controller. You configure it to the specific battery type you are using.

The manual can be found here: https://hqsolarpower.com/content/HQ...rcWt8ahWXktjeKlg87JrtgHqizgXX9k322Y46Wsl8taQ1

An alternative (and the path I chose) was to go with two deep cycle 6 Volt batteries in series. No configuration changes required and significant increase in amp hours.

I upgraded my lead acid to a 200amp lithium battery, If you have a newer trailer there is a switch on the charger to go to lithium otherwise its just changing a board on the trailer charging unit. If you don't change the charge settings the battery will still work but not charge to full potential. Best move if you don't have hookups
