Incredible details on both the video and the links. Way beyond the average youtube video. I salute you and your great knowledge and attention to detail. I am having a problem with my Schumacher SL 1315. It suddenly stopped working when I was using it to boost my battery in my 1955 Ford Crown. ( converted to 12 volt, its not 6 volt) The Lithium cell is swollen so much I can not snap the case back on. back in my past career I worked in Lithium Ion as an EE. I got back into it as an to build a S4 Lithium 230 AH set up for my motorhome. Its a learning and relearning and your video is pretty cool. thanks

Just realized you said trickle charger and not a booster pack you were asking about. I am not sure about those, I do not have a schumacher version of a trickle charger to say for sure. Do they just stop working all together? One of the most common issues I have had with any charger is a bad connection. To save money, companies use cheap clips/clamps and the connection is not even soldered alot of the time. Where the wire connects to the clip it is sometimes just crimped and subject to issues. The inside board with components can also corrode with these as alot of these are left in garages and shops. Hard to say other than these issues, it could be a circuit board issue.

Walmart near me had the sl1517 reg. 97 bucks on sale for 54 bucks so I snapped one up. Havent opened box yet. Now after seeing reviews its going back.

I recently bought a Schumacher SL1596. It’s a bigger looking one than the one in the video. It is 2500 amps apparently. Paid $330 for it, hoping it is a decent quality and will not let me down in times of need. I hope I haven’t wasted my money on it because I would have paid more for a better one if I knew this one was not great. It’s difficult to know what to buy these days with so much inferior stuff around. I’m supposed to charge it every month even if not used. I might never need to actually use it but I was thinking it’s good to know I have it onboard just in case.

Nice keep doing this

Amazing. Beyond my scope though

Sir, first I would like to congratulate you as well as thank you for your video, excellent work. I have been using Lipo Jump starters for a few years now and I would say that they have worked well when I needed them to, but the main problem is that most starters never last for more than a year or with luck, year and a half at most. I usually buy 2 starters, one for each car in my house, and I can honestly say that this experience has been a constant. After careful consideration I have come to the conclusion that the biggest issue has to do with fully charging the Lipos and then putting leaving them inside your car for a few months or until you need to use them. It is a fact that Lipos don't hold up well when you put them on storage fully charged, that is why they recommend storing a lipo at 80 to 85% of the capacity, actually most lipo chargers have a Lipo storage charge option that does this automatically. I currently have my last 2 Jump starters, both have dead Lipos of course, but instead of throwing them away and thanks to your video, I'm going to try replacing the Lipo battery packs to see if I can save them and also, instead of giving them a full charge, I'm going to give them a storage charge to see if I can get them to last longer. At 85% of their capacity they should be able to jump start a vehicle easily. Again, thanks for the vid, superb.

Appreciate the video! Quick question.. anyone know what happens if your load test an Li-Po using a traditional lead -acid auto battery resistance load tester?

@ThriftyToolShed

2 жыл бұрын

To be honest it would almost certainly damage the cells. Li-Po are being used to help boost a weak battery but under heavy loads these cells will fail! Lead acid does much better with very heavy loads as well as pulling voltage to low level. Li-Po are unfortunately finiky about over current and over and under voltage. So I use them to boost a week vehicle, but I would not expect them to hold up with much abuse. They are great for emergency use and are very light weight and convenient though. I would not put them under undue stress, that's just my opinion.

That's very interesting that the SL1316 has the LifePo cells. This is a more expensive way to go so it's suprising. The 4S makes sense for LifePo cells for sure.

Now, When I plug in the charger to charge, the LED quickly flashes blue without any numbers and immediately shuts off. Power button does nothing.

It is possible that they put on a 4S pack instead of a 3S pack I guess? First of all most packs you can look and tell how many cells are in the pack if not clear wrapped so you can count the cells in pack, you may have to carefully cut open the heat shrink around them to look. The other way to tell is if you carefully cut back covering over the connections, you can tell where the cell connections go. It might even be that the extra wire you have is simply done differently. In other words it's possible if it's a 3S pack still, that there could be a extra small wire added to the BMS instead of using the heavy gauge black and red for the monitoring. I would simply see where they connected them to cells. They must have changed board revision at some point.

I've been trying to come up with a small lesson on circuits for my students to create a led greeting card.... & I find it difficult to understand the technical parts well enough to break it down for them. So, I'm just impressed with the depth of information that goes into such a small device & I'm in awe at your knowledge & level of understanding you have in order to troubleshoot & repair it. May I ask how you know so much about this, is this information acquired when obtaining a college degree, an electrician course, or just years of experience? Where would I find someone with your level of expertise to come speak to my students & create some type of simple circuit?

Electronics is really more of a hobby. I have always loved learning how things work, how they look inside and learning how we might repair without schematics these days on most tools and electronics sold have none. I guess I am still learning and trying to share with the community as we learn. So I actually do not have a degree. I would think any EE (Electronics Engineer) with a degree could also help with your desire to show here. If you can not find anyone available I could possibly atleast share a video that could be as helpful as I could possibly make it, however it may not be in time for this Christmas at this point.

The smaller schumacher jump packs etc. are only around 4000mah or so. I wanted to use this much larger pack. They make some even larger, but they do get expensive. The only draw back to this set-up is you have to make sure you have polarity correct, which is a big deal anyway Even with jumper cables of course that's a big deal!
