LDCRE Battery Switches Editorial Review
The 20247 Battery Disconnect Switch with Lock-Out Plate has garnered mixed reviews from customers, highlighting both strengths and weaknesses in its design and functionality. Many users have reported successful installation and operation of the switch, emphasizing its capacity to handle high amperage without noticeable impacts on voltage delivery—a key requirement for those using it in vehicles such as cars, boats, and RVs. One user specifically mentioned using a zero-gauge cable with great success, further validating its performance capabilities for demanding applications. However, installation has proven to be somewhat complicated, as the switch comes unassembled, requiring users to engage in a more hands-on approach to complete the setup. Some customers experienced frustration due to the switch’s size, which they described as "monstrous,” complicating installation in tighter spaces. Additionally, several users noted concerns over build quality, with reports of switches breaking during installation, missing parts upon delivery, and finishing durability being questionable. On the negative side, a few reviews highlighted instances of poorly made components that have subsequently led to operational issues, including one user suggesting it caused starter problems in their truck. While there are positive remarks about the switch working as advertised, the longevity of its performance remains uncertain, with examples of failures within just a few months of use. In summary, the 20247 Battery Disconnect Switch may appeal to those looking for a high-capacity solution at a budget price, but potential buyers should be aware of its installation challenges and variable durability. **
