I started using this product to connect my 12V LiFePo4 battery string to a homemade solar generator. It works very well and this product is good for 12 volt terminals. The Angles 90 grips are very good for connecting thick electrical wires (you need to bend the wires if you use regular straight grips) when connecting other batteries in parallel. The only problem is that it's a bit difficult to open the plastic handle cover. I recommend this product for your side projects.
