Rechargeable battery packs

I built a Lithium Battery Pack to store Solar Energy for my Yurt using 18650 cells. Join me as I go through the various steps and explain some of the basics of building custom Lithium-ion Battery Packs.

Converting two - 4S20P battery packs into one 7S20P pack for the new 24V lithium ion power wall. The 4S battery packs have been in daily use for up to 2.5 years now in the old 16V system. Time to convert them over for the 24V system. Very little change is required, only longer pieces of threaded rod and a longer piece of wire for the power connector. For each 7S pack converted, I end up with one additional 20P module. These will be tested for capacity and then a plan worked out for re-using them in new 7S packs. I'll need to make some 7S balance cables, so stay tuned for that in the next video... Subscribe for more content like this.

In this video, we're going to talk about the pros and cons of both buying and building a lithium battery pack. We'll cover the important factors to consider before making a decision, and help you choose the best option for your needs. Lithium battery packs are a great way to boost your personal energy storage, and this video will help you choose the best one for your needs! We'll discuss the pros and cons of both buying and building a lithium battery pack, and help you make the best decision for your needs. I will show you what method I used for my Truck and Trailer and discuss my reasons for my decision. Depending on your skill level with batteries, you may choose to Buy or Build. Sometimes you might just want peace of mind and are willing to spend a little extra money!

Processing a batch of 8-cell Arris cable modem batteries to build additional battery packs for the power wall. Working with lithium ion batteries is inherently dangerous. Be sure you are experienced at doing this kind of work and take adequate safety precautions before attempting this yourself. The techiniques illustrated in this video are for entertainment purposes only. There are likely several ways to open these packs. I found this technique worked best for me. It was fast and involved no cutting with sharp blades. I experienced no cell damage in opening hundreds of these packs using this technique, YMMV. These batteries seem to have two different LG cells in them, the older LGCAS31865 and the newer LGDAS31865, both rated at 2200mAH, 1075mAH nominal charge rate. I picked up 80 battery packs, netting 320 pair of cells for testing. I think I had 2 - 4 pair of cells that tested out below 2000mAH, those I'll need to separate and see if any of the individual cells are still good. The average capacity was 3623mAH and the median was 3613mAH. This comes in higher than my existing new and used battery module capacities, so I'll probably use the upper end of this group to build some higher capacity modules and then some of the lower ones to build some 35AH modules to match the 4 - 35AH modules I have left over from the old 4S system.
