Hello, you do some really good work brotha. I would like to send my Noco to you but I am in England. I have the same GBX155 4250A, I have checked the diode which is ok and it's showing 3.18v across the positive and negative on the battery terminals (when i hold power and light button all leds flash on then off), the capacitors visually look good and don't look blown, But it won't change, is there a minimum voltage the battery must be for it to charge with USB C? Much appreciate and God bless from across the pond 🇬🇧.
@@SOSfixElectronics Hey my brotha, i de-soldered the battery terminals from the board and used a 12v (2-4a) battery charger to bring the voltage up to about 12.8 volts then put on charge with a usb for 2 days. And now it works great. Thank you very much for putting out informative content.
I have a GBX155 mine is charged however it won’t output power or boost anything. The light works however looks like not all of it is on. Just wondered where I should start or how to go about fixing.
So in this video nothing been fixed, as only needed to charge battery. On gb 150 charging current goung up to 1.6A from usb is it not too high? Shouldn't it be just below 1.5A?
@@SOSfixElectronics i got on one of my gb150 power button push turning one, then press again coming up 100% green light, press again may click boost relay with voltage indicator and all this from onr power buttom and randomly. Any idea what can couse that?
Hi, I have used a Dc power supply to charge a flat battery to 12v However when i swap over to usb c the red charging light comes on and only 1 red bar 25%. Any ideas
@@NAY2GAS Tried that would not work. However i have fixed it. I just charged it with DC a little longer and slightly bumped up the Amp. All works as it should thanks to this video 👍
Tengo un problema he puesto a cargar el arrancador noco3000ah,en una grúa que es de 24v y el arrancador es de 12v y ahora no arranca los vehículos pero supuestamente está cargado completo y enciende la linterna que le abra pasado
Displey on gb150 showing voltage vhen you connect clamps to the battery. If battery is fully dead, it is not showing any thing. If battery has like 6-9 v it is showing battery voltage. When you syart engine it should show around 14v. This is volage of battery when alternator charging it. If you see on running motor about 12.5v mean alternator need attention
Hello. Is there a way that you can comment with the address where we would need to send out the GBX155 in order to get it fixed by you? How much do you charge to get it fixed?
@@dougybach The GBX155 does have a 4 cell battery pack, open circuit voltage is over 16v when charged. The lower end models GBxx have only three cells.
@@NAY2GAS I did. The charging indicated fast charge for a few seconds then went off and red light came on. I fixed it in the end by following the guide and charging a little longer. All works fine now
Great work - thank you for sharing, your insights are helpful
Good work and pointers, cheers.
Glad to help
Could you share where you obtained the battery replacement? I'm from the UK and I would like to learn and have a go
Great stuff

yes battery most be 9v or more, for gbx charge the battery with external power supply first

How do I send mine to your place in order to be fixed? What address?
I have one and charging port is blown, are the small boards used for charging available anywhere?
Yeah all over Amazon lol just lipo charge/management board … actually don’t even need it if have good rc charger and sun commen sense 👍
Thanks for video. What you using to charge gb155? It takes 12v but usb is only 5v
usb-c laptop charger 19v

Hi, I have found on my GBX55 an SMD component D19 close to the USB C charging port blown. Would you know what the component is, please? Thank you.
regular diode +20v
Still doing repairs on noco battery? My gb150 does not jumpstart cars and digital dosplay does not show when connected to a car.

Ok so should I buy GB150 or GBX155?
Do you know the cell count for GBX55? Is it 4s or 3s? Thanks
4 cells 4v each
They are not a 4cell lipo

Would anybody charge me to fix mine? I have a 24 V.
PLUG IT IN YOUR CAR IT WILL CHARGE AGAIN
Then, after 15 minutes it will charge on your regular charger
plugged into my cig lighter it still didnt hold a charge
Didnt work for me either
@@stevenharris2190I heard you have to have the car running and plugged into the NOCO for 15 minutes. Did you try like that?
@@NAY2GAS I did. The charging indicated fast charge for a few seconds then went off and red light came on. I fixed it in the end by following the guide and charging a little longer. All works fine now
