TQ Wire 2S Charge Cable w/4mm & 5mm Bullet Connector (2')

I STRONGLY prefer this cable over the Trinity options, for the main reason being the universal plug design, which is MUCH safer than the other designs on the market. The plugs on this cable start out as 4mm, and then taper larger to 5mm to accommodate both sizes on the battery end, which means that during use, there are no exposed unused plugs. On the trinity cable, the 4mm and 5mm plugs are opposite each other, meaning whichever end you don't use, will be standing straight up when you plug your battery in, and will be both exposed, and live with power. One mishandled wrench or tool that falls onto the battery during charging, or accidentally touching both terminals with a metal watch band could lead to a VERY bad situation. This cable from TQ is well designed, flexible, and well built. With proper use, it should last a lifetime.

I don’t think I would buy these again. What they don’t describe is how long the 4mm portion is. What I have run into is the batteries are to short to be charged in car. I put pucks in bottom of batters to be certain I don’t short out batteries.

What would be better is just buy a 4mm cable ends and buy the $4 adapters. Would be less hassle of a design.

This product is great! No messing with different connectors when using 4 or 5mm inboard batteries. Just plug right into your charger and/or balance board.

Very good quality. Allows me to charge both 4mm and 5mm batteries.

I upgraded to Orion shorty packs and they use 5mm female post connectors, I was setup for 4mm. This did the trick for a charging cable. it can do 4 and 5mm. very high quality and make the pit area look a lot cleaner.
