XT90 Spark Resistant Connector (Set)


Current stock: 0
  • Includes 1 male and 1 female
  • Spark Resistant feature solves the annoying spark problem when connecting the battery
  • Can easily handle 50amps of continuous with no problem (rated at 90A continuous)
  • Will mate to original XT90 

Spark resistant means you plug them in and they don't do that annoying spark. Less scary and it will not trigger your BMS to shut down, and the connector will last much longer.

This is the sweetest ebike connector made.  (read our guide to ebike connectors)

A necessity for people who tend to use their battery plug as an on/off switch (read our story on on/off switches on ebikes)

So far So Good

Using as a power switch interrupting the 10awg power wire on an 89" AJ Slick with 12s (50.4v fully charged), with a160amp ESC. No spark on plugin. I made a flange out of fiberglass to mount the female part of the connector to the plane, and joined the poles in the male part of the connector as described at 0:53 this video: https://www.youtube.com/watch?v=x8PTvJJClLU
