Can you do same upgrade for the newest Sherpa 100 AC and PD versions? I have the newest versions as well as the ones from a few years ago, same design except for the tilted display screen on the newest (2024) versions.
Hey buddy, love your videos there brilliant! Subscribed to you. Your videos are very helpful as iv always wanted to know how these look inside.as iv wondered if your able to upgrade the batteries!! Thank you for sharing 👍👍👍👍👍☆THUMBS UP☆👍👍👍👍👍
I have watched your video many times, so attempted to change the batteries on my Goal Zero 100. I give up. I have redone it so many times and still have that darn error. I believe that I put it together correctly but no go. My soldering efforts leave a little to be desired. My question is do you want to try to repair it for the boy scouts? It may be beyond repair at this point. If yes, where do I send it?
My Friend, I have a sherpa 100PD 4th generation (not ac version). Do you know/can you help me open it without destroying the case? It has bad cell (i'm pretty sure) and need to open and replace it. there are screws in the back and slide off rubber pieces on the side but no obvious way to remove it from the aluminum case after that. No visible screws or snaps on the front face. Your help is appreciated. Of course, no assistance from goal zero given on disassembly. Thanks. Terry
Have you seen a case where you connect the new batteries, test them get the battery display to read a % charged, in my case 80%, and then go back to battery error? I checked all my weld and solder points, checked continuity across the batteries and voltage across the stack and all seem positive. Any suggestions?
Hi, I have the same Sherpa 100 and today it started flashing both the 12v and Laptop circles after I plugged in a piece of equipment via the 12v car adapter cable. Shows the battery fault icon and the current state of charge 80%. I'm able to turn on the little led light but the USB ports are not working. Any advice as to what it may be? Is there another fuse inside between the 12v and battery that may have blown?
Hi AerialWorks, i have a sherpa 100 and there are times i cant turn it off. The battery indicator appears but no blue back light. Ive already sent it to our local goalzero distributor and repaircenter but they werent able to fix it. Any help will be greatly appreciated. This videos gave me another hope to reuse my sherpa. Keep up the great work
It sounds like either a switch problem or something haywire with your circuitry. Sorry, but GZ doesn't offer any repair parts so it looks like you are out of luck.
No idea. I tried to locate one for two years and Goal Zero was never able to produce one. One of their salesmen suggested that after the initial production run demand was low so they never made any more. Irrelevent now because the old Sherpa line in this video is now obsolete & been replaced w/better, higher capacity units at a lower cost. Good luck!
Don't use a knife or anything sharp to pry those batteries out. I can tell you from experience that they puncture easily and shoot a fountain of sparks just like fireworks. Also, storage charge for lithium ion batteries is not 20%. That will severely shorten battery life. The manufacturers say 40% but these batteries are designed to stay at 90 - 100% for best performance.
They would not know. But if your battery did burn, blow up, etc.. and they found out it was modified through the investigation, you would be charged with a crime. If the plane crashed and/or people were killed you will be in prison for a long long time for pre-meditated homicide. So basically, don't do anything you are not supposed to... even if no one is watching :)
> and they found out it was modified through the investigation, you would be charged with a crime. And you think the removal of the sticker would somehow absolve you of that crime? That's not how it works.
There are no 4200 mAH batteries. They are fake. I test batteries all the time. I just bought and tested a battery labeled 5,000 mAH and it tested at 1100 mAH. Best way to tell is the weight, if you do not have a charger that tests mAH. Get a real 18650, it will be MUCH heavier than a fake one. Very noticable.
Panasonic's do look like that, it's just that unfortunately you can't tell by pictures because it's merely a heat shrink wrapper anyone can copy and use on junk cells. Best way to tell if they're genuine is just using a smart charger and seeing how much they take from full discharge. Knockoffs won't even bother being anywhere close to 3000mah, because it's too expensive to manufacture that much capacity.
Would the NITECORE NL1835 - 18650 3500mAh 8A 3.6V work in this Sherpa? I'd like to upgrade and want maximum capacity. Perhaps going for the extra 100mAh isn't worth the price difference.
They didn't use those cells because it was "older technology", they did it so it would make the pack compliant with TSA regulations and guidelines. Can you make a bigger pack with cells that have more capacity? Absolutely, but now you can't travel with it.
You sir are a legend! You just saved me $400 and improved my Sherpa.
THANK YOU
Super, thank you for this video about Sherpa 100 and 50. I have one 50 and one 100, and others Goal Zero products.
Glad your back sir. Much fun to watch your channels.
Haha. I was watching this and thinking, “I know this voice! It’s Bill!” Haha. Love both of your channels.
what is the other channel???
Great work! With compliments!
I would have disconnected the 25 amp fuse before further disassembly
Great video! Thanks for the info!
Can you do this with the new Sherpa 100 ac portable power bank ?
Sir, thanks for the vid. Considering the age of this is there a newer battery that you would suggest using now in 2020?
it look like slow charging only. No individual cell status monitor wires.
Can you do same upgrade for the newest Sherpa 100 AC and PD versions? I have the newest versions as well as the ones from a few years ago, same design except for the tilted display screen on the newest (2024) versions.

I appreciate your offer, but this model is long obsolete and there are now better options out there that don’t cost an arm and leg.
Can you show us your spotwelder...? Are you using one for 18650's or just a generic one...? Thanks...

Please send your info to send you 2 GZ 50 & 100 to get them fixed. Thanks a lot,
How much would you charge to do this ? If i ship in my sherpa 100.

@@CraigLucca check your fuse. If not that, then the circuitry’s gone squirrely.

in case you didn't mention it, going over 100Wh means you can't take it on a plane.
Just dont chage the label, so you still can.

How about tha Sherpa 100 pd , can you show us
Where do you source Li-NMC cells?
hey i didn't know you have this channel. those look like bill's hands.
*peals sticker off* ~Boards Qantas~ [Crashes]
Hi, where can I get a chaining cable for Sherpa 100/50? Please advise

So you are saying to remove your sticker before taking it on the plane? :-) I mean would they know without taking it apart?
They would not know. But if your battery did burn, blow up, etc.. and they found out it was modified through the investigation, you would be charged with a crime. If the plane crashed and/or people were killed you will be in prison for a long long time for pre-meditated homicide. So basically, don't do anything you are not supposed to... even if no one is watching :)
> and they found out it was modified through the investigation, you would be charged with a crime.
And you think the removal of the sticker would somehow absolve you of that crime? That's not how it works.
Is it possible to upgrade it to lifepo4 and replace protection on it ?
do you offer a service to repair and upgrade these units for the public? if so how much would it cost?
No, sorry.
There are also 4200mah 18650 batteries. But I only see them with a point. Would those also work? Is there room for the battery with pin?
No, there is no room. Also, the 4200s are probably fake.
There are no 4200 mAH batteries. They are fake. I test batteries all the time. I just bought and tested a battery labeled 5,000 mAH and it tested at 1100 mAH. Best way to tell is the weight, if you do not have a charger that tests mAH. Get a real 18650, it will be MUCH heavier than a fake one. Very noticable.
Anything above 3500mah is a fake. This will not change until the glass/solid state batteries are available to the public.
How much to change batts?
Are you able to do this for my sherpa 100 and sherpa 50? I am ready to pay for the battery at csot and pay you for your time.
Do you know how to fix the infamous fuse failure light? Even after replacing the fuse with a known good fuse?
Usually it means one or more of the batteries has an internal short caused by overdraining it. Sorry for the bad news.
Very helpful!
Hi, I did the same battery upgrade for my sherpa 100 but at 60% the battery fails. Any advice? Thanks
It sounds like youmay have overheated one or more of the batteries while soldering.
@@bosnianbill I did check the voltage of each battery before setting them up. Also I charged each battery using the 18650 battery charger.
I still take that on that plane. peel that sticker off.
What source are you using to ensure genuine brand 18650's? I've had terrible luck with eBay, mixed results with Amazon.
Yep, they look like fakes!
Panasonic's do look like that, it's just that unfortunately you can't tell by pictures because it's merely a heat shrink wrapper anyone can copy and use on junk cells. Best way to tell if they're genuine is just using a smart charger and seeing how much they take from full discharge.

Yes it will work if you have the $$
Bad idea. I think the sherpa has a 25A fuse. Thats to much for 4 cells inparalele.
Hi Bill, what spot welder do you use, I've seen someone on youtube using a 12volt battery for doing this? Always wanted to have ago
ha ha "cant" amiright
They didn't use those cells because it was "older technology", they did it so it would make the pack compliant with TSA regulations and guidelines. Can you make a bigger pack with cells that have more capacity? Absolutely, but now you can't travel with it.
On easyjet its 150wh
would you make me a pack zerpa 50and how much
I’m a girl and not very handy. Can I pay you to build a battery pack for me?
what is "awesome" about MODIFIED SINEWAVE on AC ? It should be PURE SINEWAVE! think about it!
For what device? Most smale electronics use switchmode psu any way, most of them even work on dc power.
