The key difference with the V3 is that it used a bare bones copper PCB to mount the through hole components to. No longer will you need to solder bare wires to the bottom of the relay. Instead, fit the relay to the board and solder the pads directly to connect everything up. The wires are replaced by the copper traces in the laminate.
We retain the stock mechanism switch in order to protect the cycling system from over run and general bugs. The stock loom can be wired to a JST line and then plugged directly into the board using the V3 kit. We provide two header pins for the stock mechanism switch and the blaster's on/off switch to be plugged in.
The complete kits includes all the wiring lengths you need, all the JST plugs to solder to the stock loom, heat shrink tubing, fuses and fuse holder, all the through hole components (relay, FET, resistor, header blocks), the PCB, a battery connector of choice and of course our standard 6kg Stampede upgrade spring.
The entire V3 kit is available for £18 (correct at the time of writing) via our website. Dispatch time is subject to our lead times policy.
