Frequently Asked Questions (FAQ)
- • Why does my XP750CK help with dimming but not completely fix voltage drop?
Some users reported that the XP750 helped eliminate dimming lights, while another owner running around 1,500 watts still experienced voltage drop at stoplights and with the A/C running. This shows that the kit can improve electrical reserve, but it cannot replace an alternator that is too small for the overall load.
- • Is the XP750CK enough for a 1,500-watt audio system?
The kit is marketed for 500–1,500-watt systems, but real-world performance depends on the vehicle's alternator and how the system is used. One user with roughly 1,500 watts found that the XP750 helped but eventually needed an aftermarket alternator to control voltage drop.
- • Why did my stereo need retuning after installing the XP750CK?
One verified buyer said that after installing the XP750, the additional available power was significant enough that they retuned their audio system. A change in electrical stability can affect how an amplifier behaves, particularly when the system was previously limited by voltage fluctuations.
- • Do I really need an isolator with the XP750CK?
The kit is designed as a supplemental battery system, and one customer specifically recommended using a battery isolator for their application after experiencing improved performance. Whether an isolator is appropriate depends on how the secondary battery is connected and whether you want to protect the starting battery from accessory loads.
- • Why can't I simply install the XP750CK under the hood?
The XP750 is specifically described as a supplemental battery that is not designed for under-hood installation. Its intended use is as an additional power source located away from the high-heat environment of the engine compartment.
- • What if the included 4-gauge cable does not seem long enough for my installation?
The XP750CK includes approximately 18 feet of 4-gauge power cable, but the actual routing depends on where the secondary battery is mounted. The installation instructions require the cable to travel from the front battery through the vehicle to the secondary battery while avoiding exhaust heat, moving components, and unsafe drilling locations.
- • Can I leave the IntelliCharger permanently connected to the XP750?
A customer specifically asked about cutting off the charger's alligator clips and permanently attaching it to the battery. Crutchfield advised against modifying the charger because XS Power does not specify it for permanent installation.
- • Why does my XP750CK still need a proper charging system?
The secondary battery stores additional energy, but it does not create electricity by itself. Real users have found that a supplemental battery can improve voltage stability while an inadequate alternator still causes voltage loss under heavy loads.
- • What should I do if the XP750CK arrives with a bent mounting component?
One verified buyer reported receiving the product with a bent metal component, although they still described the battery as good overall. Inspect the mounting hardware before installation and contact the seller if shipping damage prevents safe or secure mounting.
- • Why does the XP750CK need to be fully charged before installation?
The XP750 is an AGM battery, and improper charging can permanently damage it. XS Power's installation guidance emphasizes charging the battery correctly before use, while the kit instructions also require careful fuse placement and secure cable routing during installation.
