Well Made

I used this product for my extra battery install for my subwoofers and it went beyond my expectations

The best

Heavy duty and the right length for my usage. Allowed me to place battery on wheel well to start skid-steer when on board one died. couldnt replace on board one with arms down. Couldnt raise arms without it running.

I use these for my battery bank solar system. If you need to wire multiple batteries together, its very important to use the same size/length wiring for your battery bank for charging/discharging. You dont want some batteries to starve while others are being overcharged. Batteries are expensive, so wire them up properly. Such a small detail but it can pay big dividends. And of course, use the correct feedpoints in your battery strings for the same reason (where you wire them to your inverter or charge controller.) Google has plenty of picture examples, so dont guess at it. And of course there are solar forums that cover this. I have four 12-volt batteries for my 24v inverter, so I needed two series strings wired in parallel. I almost wired them wrong and could have shortened my battery life using different sized cables.

These things are heavy duty. Used them to connect my batteries in parallel on my sailboat and needed good solid cables, these fit the bill perfectly.

Caution check that both ends are crimped on properly, the negatives ends fell off with a slight tug. Only held by the heat shrink. Used the positive and when adjusting it after a week of use also came apart. Thankfully I wasnt driving, and I had already gotten a lug crimper for another project. Otherwise they seem to be of good quality and have enough flex to accommodate awkward positions.

Works perfect for my 3000w inverter.
