This is a small upgrade I’ve been wanting to do for quite some time The battery connector is one of the least dynamic, but at the same time most important components on the car. I hate how just plain soldered connectors force you to risk metal fatigue on the soldered joint and battery toesc wire every time you prepare the car for a run.
For £9.99 and shipping, these Core RC connectors totally solve that. They give you excellent grip to remove the bullet from the battery and tug on the connector directly not the joint or the wire. Plus, they reduce heat in the wires/battery, which I presume is a good thing. A little pricey, but the look great, actually help with pos/neg lead identification and make the electrics that bit more durable . Highly recommended.
5 Stars, pretty, functional, well made, even if they are a copy of the 1up connectors, at least you can buy them in the UK now.
