Good connector within A/V bay for charge leads

I've used direct connections (e.g. ejection starter wired to altimeter terminal) for charges for electronic deployment, but for a new 4" a/v bay, I'd like to use some type of plug/jack connection for times where the bay needs to be fully disassembled.

Right now, I've wired up the bay with molex 0.062" 2-pin connectors which are good to 5A but are only rated for 25-30 mating cycles. For size, I'm interested in the JST RCY connectors: https://www.jst-mfg.com/product/pdf/eng/eRCY.pdf but the data sheet doesn't specify the number of mating cycles one can expect.

Does anybody have a reference for JST RCY mating cycle rating? I'm also curious about the connectors I've seen at doghouse rocketry.

What's in your a/v bay for this type of application?

I'm using Anderson power poles: https://www.powerwerx.com/anderson-powerpoles/powerpole-sets/

I like the Doghouse terminals. They ship with all the parts needed to install, right down to the small hex key. If you order one of the altimeter wiring kits, the terminals are included in the package.

Also take a look at the charge wells and combined charge well/terminals.

Excellent customer service and extremely quick shipping.

+1 for Doghouse. Everything they sell is first-rate, and their customer service is awesome.

I do like their charge wells and this build is sporting them. I've got some needs for rail button standoffs for an Estes Ventris, I'll get some connector whips too.

Although I'd have to admit, the mating cycle count of 10000 for the power poles is impressive!

One of the best connectors ever made. All rated to 600 volts. Also available from https://www.mcmaster.com/#catalog/120/788/=uslgek

Mini Tamiya Connector from Hobbyking or eBay

I'm using the JST with no issues. eBay was the cheapest for them

I generally prefer no connectors, but if you absolutely need them R/C plugs such as Deans Ultra Plug work well. (They're built for high-vibration and high-current.)

Do those use a standard crimp, or do they need a special mandrel? I have an aircraft grade ratcheting crimper.

https://www.andersonpower.com/products/singlepole-connectors.html is the parent page. The connectors are not that small but they are good. A good application is for connecting launch clip leads to the controller wires.

I just use a standard wire stripper crimper.

I solder them.
