One-stop shopping for your second battery

If you're putting together a serious, competition-level audio system, you know you're going to need extra power. And you also know that putting together all the parts and pieces you need for that part of the project can sometimes be as challenging as designing the stereo system itself.

XS Power's XP750-CK kit takes the legwork (and guesswork) out of adding a second battery. This complete kit comes with everything you need, from the compact, powerful XP750 power cell all the way down to zip ties and screws.

This XS Power kit includes:

  • 1 XP750 power cell
  • 1 stamped aluminum battery mount
  • 18' XP Flex power cable
  • 3' XP Flex ground cable
  • 6 XS power heat shrink
  • 6 crimp terminals
  • 2 battery clamps
  • 2 wire grommets
  • 2 ANL fuse holders
  • 2 150A fuses
  • 10 wire clamps
  • 10 zip ties
  • 10 screws

 The included XP750 battery is designed for 500-1500 watt systems, and you can use multiple kits for systems that require even more power. Warranty: 2 years

Features

Overview: The XS Power XP750 is a 12-volt battery that is designed to be used as a supplemental power source in your vehicle. It can be used to provide additional power for your car audio system, or can be used in marine applications. It is not designed to be installed under the hood or replace the OEM battery in your vehicle.

Terminals: The XP750 battery has a terminal insert with an M5 thread. It comes with socket cap head bolts that allow you to fasten the ring terminal to the battery, so no additional hardware is necessary. The XP750 is not compatible with other terminal adapters offered by XS Power.

Absorbent Glass Mat (AGM): XS Power's AGM (Absorbent Glass Mat) batteries use a fibrous material to suspend the liquid electrolyte against the lead plates. Because the electrolyte is absorbed in the material, there is little chance of an acid leak, even in the event the case is ruptured. AGM batteries contain more lead compared to traditional "flooded" batteries, thus producing more power.

Installation: In typical car stereo applications, XP-series batteries are installed in the trunk or hatch of the vehicle, close to the amplifier. It should be wired in parallel (+ to + and - to -) with your vehicle's battery. The positive lead is run back to the main battery, while the negative lead should be grounded to the vehicle's metal chassis near the secondary battery. A second battery install kit, such as the XS Power AK1000, can be used to connect the XP750.

Specifications: The XP750 has the following specifications:

  • Maximum Output: 750 watts
  • Reserve Capacity: 28 minutes
  • Discharge Capacity: 22 Ah (amp hours)
  • Dimensions: Length=7.13", Height=6.57", Width=3.03"
  • Weight: 14.5 pounds

Great little kit for an easy upgrade

Written By Matt, Wisconsin Dells, WI on Friday, June 13, 2014

Crutchfield Customer Review (What's this?)

Firstly, I have to say that this is a great little kit that includes everything you need to upgrade your existing battery or add a second for more juice.

All of the parts were packaged nicely and come as no-brainer as possible. Everything is pretty self-explanatory as far as the install, and everything is pretty high quality.

I only have two qualms with this product. The first problem I had was that this kit includes 4-gauge wire to wire everything up; that may or may not be thick enough, but when I'm adding such a powerful setup to my car, I would expect 0-gauge wire or at least a 2-gauge minimum. I bought my own 0-gauge wire and crimped ring terminals on myself (the fuse holders included will accept up to about 1/0-gauge, which is nice); when running two batteries together (especially as far as 17-feet) I would expect something bigger than 4-guage. Secondly, there are no in-box instructions for the install. As I said earlier, it is pretty self explanatory and there are instructions on the back, but if you are a beginner to this type of thing you may need to do some more research before installing this kit.

Again, overall this is a great little kit to get the job done. Make sure you know exactly how you are wiring your setup before you install this to avoid any headaches, and consider upgrading the cable to something a little heavier duty (even though it requires work time and effort on your part).

Pros: Battery holder for easy-install Dual fuse holders (fuses pre-installed, accepts up to 1/0-gauge wire) Easy installation Post-mount converters for multiple terminals (excluding the need for a distribution block)

Cons: Thin (4-gauge) wire for a large project

Amazing quality on this product for such a good price. Love how the cables came with terminals already attached! Highly recommend this product!

Good addition

Crutchfield Customer Review (What's this?)

Good product and a good addition to my system. I'm not sure if it was needed but it does help a lot with the headlight dim. Have one alpine mrp-f300 hooked and plan to hook a sub amp to it as well around 600 watts. Kind of hard to install

Pros: Good product. Good quality. Everything included. Fixes headlight dim

Cons: Hard to install in my case
