Charging port & Smart Charger

[ARobb73]

I've just installed a CF8 with CeX, RICE and Recharge port to the 7.4v battery.
When I try to charge it, the LED on the charger goes green and the LED in my switch flashes on the saber. This is after switching the negative wires on the recharge port
because when I originally wired it the charger would turn red, blink red then go green - I thought maybe i'd switched them around after reading a few posts here.

I'm not seeing anything in the manual, any suggestions would be great.

Thanks!

pictures of your wiring would probably be helpful in the diagnosis process if you can get them!

I'll have to take it apart for that, and since I'm going to retool the chassis anyway I'll probably end up rewiring it. I was hoping that the symptoms would give something away in my miss wiring things.
Thanks Cire

Plugging in to the recharge port should kill all power. If your switch LED lights then I would suggest crossed negatives on th recharge port.

Thanks Greenie.
I ended up gutting the saber to take a closer look at what is going on with the port. I isolated the port from the board (only connecting the battery bits & not the board) and tried to charge the battery. I got a solid red light for a second and then it switched to solid green. Something is bad in the mix, I'm just not sure what (maybe?). Being my first recharge port attempt I was a little nervous about it, but at this point it's kind of disheartening to have nothing I try work. So rather than get stuck on this, I'm thinking it might just be easier to retool the entire thing to single cell and make it removable as I've got a TON of the individual 18650 batteries for my other saber.
I'm still curious why it's acting the way it is, even though I'm thinking about moving away from it.

If you can, take a picture of the recharge port wiring. We'll need to see how it connects to the battery and the other electronics.

As requested. Pulled everything apart, removed all wires to the board - it's only wired to charge the battery. Still the same symptoms, plug the charger into the wall, it turns red for a second and then turns green. Plug charger into recharge port and it stays green. Unplug charger from wall and then back into wall, red for a second and then back to green.

That certainly appears to be wired correctly. It's possible the recharge port is defective. If you have another way to hook up the battery to the charger, you could rule out a defective battery.

Thanks - Good to know I'm not completely nuts.

I know the PCB protection works - The saber ran until the battery hit minimum charge and it shut down. I've got some friends that have a charger that can switch out battery type and connections and tests the battery first - I'll have them give it a charge and see what shakes out. Funny though, I'd never even given it a thought about the battery being bad.

From most likely to least likely defective:

1. Wiring
2. Recharge port
3. Battery
4. Charger (or just charger settings, if it has multiple modes)

Seeing as how the saber ran fine, I'll assume the wiring polarity is correct. Recharge ports are inexpensive to replace, and it's not terribly hard to rig up a charging method to test the battery/charger combo. Direct wiring with a JST disconnect works fine.
