RC Pro plus ESC/Motor solderless connectors

[awfireman]

I have ANOTHER question....do ESC to motor connection need to be waterproof or close to it? I bought these solderless connectors from RC Pro PLus but the housing that fits into have slotted open spots for cooling and so there is no metal on metal contact. Should I waterproof these or are they ok installed as is? I know water and electricity dont go well so I was worried about them getting wet through the opening on the housing. Thanks again for any advice.

The connectors need to be electrically insulated more than they need to be water proof. I would recommend a conventional 6mm gold plated bullet connector and then a layer of heat shrink over the connector afterwards. Bad connections cause resistance, which creates heat. Those solderless connectors scare me.

I wanted to try them as I know some friends that use them on the basher RC Trucks. I also used RC PRO 7mm solderless connectors on the batterys...I couldnt pull them apart after inserting both grub screws. I got everything hooked up and ran the boat this morning. EVERYTHING was much cooler on 6s and tried out 2 - 3s Genace 8000mah packs with a super-long run time. Zero issues running full throttle and got a 8.30 run-time. I did take you advice and heat shrink the housing on the solderless esc connectors. Thanks

Glad the test went well. For the record, anecdotal electrical data from other forms of RC doesn't always translate well to boats as we pull significantly more amps, continuously, than they do.

In larger power systems, (400+V, 800+ Amps ) I use connectors that have both a mechanical connection of a set screw, and get out the torch and sink it full of solder. Mechanical strength and electrical conduction.
