 ## Motor upgrade

   * [This motor](https://www.aliexpress.com/item/4000250072388.html?spm=a2g0o.order_list.0.0.21ef1802ozHCez) has been verified to handle 250 phase amps and about 100 battery amps though it gets hot fast.  
   * If you push it hard you'll need some heat sinks like [this]([http://someoneFindALinkPlzkthx](https://www.pwmall.com/p-210643-50_126-delavan_heat_sink_fits_all_4_diameter_delavan_motors_7870_7970_7871_7971_fb_series?fbclid=IwAR1qtVtE8GrEi5lMz8ljRAmksvRH3bCqQk6Q1Tn-cePhvMYAo2bQ8pyqhgA)): ![this](images/heatsink.jpeg)

 ## Connectors
 
 * [XT90s](https://www.amazon.com/Amass-Connector-Anti-Spark-Battery-Charger/dp/B074PTHZ3M/ref=sr_1_2?crid=374B062FKB4N2&keywords=xt90s&qid=1645583218&sprefix=xt90%2Caps%2C344&sr=8-2) connectors for the battery is recommended to avoid sparking when plugging the battery into the controller.
-  * Stick with the amass branded connectors. 
-  * They are rated for 100a.  If you have a 300a battery you can just use 3 connectors for example.

   * They can use up to [10 gauge silicone wire](https://www.amazon.com/10-Gauge-Silicone-Wire-Feet/dp/B007DMW3IU).  Any larger than that is a waste and hard to solder.
 * [Bullet connectors](https://www.amazon.com/Generic-5-5mm-Gold-Bullet-Connector/dp/B01MRXLVRD/ref=sr_1_4?keywords=5.5mm+bullet+connector&qid=1645583504&sprefix=5.5mm+bull%2Caps%2C221&sr=8-4) for the motor phase wires.
   * See the image below for amp ratings.  I use 5.5mm bullets for everything because they do about 100 amps.  If I need more amps I just do 1 connector per phase per 100 amps.  I basically just match them up with the same number of XT90s connectors I use.  ![amp ratings](./images/bullets.jpeg)
   * Depending on the controller you get you'll want to replace the phase wires to use bullet connectors so that you don't have to use one of these shit boxes: ![shit boxes](./images/shitBox.jpeg)
   * The shit boxes are nothing but problems because the plastic melts easily when the nuts come loose.  I have seen this many times and it usually does'nt end well and can take your controller down with it.
-  * If your controller has built in phase wire mounts(like the one below) you should be fine to just go with whats built in. ![ok controller mount](./images/kelly.png)
