The document that was posted showing the shipping restrictions. THIS DOES NOT APPLY TO THOSE THAT ARE CERTIFIED AND TRAINED HAZMAT SHIPPERS. -Signed, Someone who works at a second life storage/battery recycler who has received some of the training in order to become HazMat Certified (but it...

Please don't post if you are not educated enough to provide accurate information and your post is defaming the character of a seller. This document on page 10 outlines some of the details. If you are a trained HazMat shipper then it is not illegal. You have no way of knowing if this seller is...

So I bought a 12S8P 26650 pack to chop up into thirds for 12V packs. I made the dumb mistake of taking one of the thirds and removing each cell from the nickel plate its spot welded on to. Huge mistake Obviously one of the main problems is if you're not careful you can rip the nickel off and...

And the Lipos must be stored at nominal voltage to prevent serious degradation.

Lipo C ratings are an entire clusterfuck in their own right. The Wayne Giles ESR meter is the best tool on the market for determining the ACTUAL C rating of Lipos. Cylindrical 18650/21700/etc made by the big name manufacturers have real datasheets. Many of them slightly overstate discharge...

I see it’s a 50Ah battery…so a 1.75A discharge would take over a day….but with 200 cells I think it’s worth buying the $25 load tester and if you don’t own a variable power supply I can point you to some cheap low amperage options. You could even cheap out and get a simple buck converter and...

2.0V isn’t danger territory. This pack still has a good chance of being revived with minor degradation. So long as no group sat below 1.5V for a long time they will usually come back to life you just must charge slowly with a variable power supply. For each cell in parallel I recommend charging...

Find a small pack of M1A’s on eBay or check BatteryHookup. I know Battery Clearing House has or had degraded M1A packs fairly cheap considering it was dozens of cells in a pack Or make a post on a few forums asking if anyone would donate or sell some M1A’s. Specifically degraded ones. Best to...

I bought one of these before he put up the listing for the NEW packs and just had the lightly used packs available. With a light load (8A?) I got 99% Ah and Wh....when I got a larger load to test with I think I did 15A and the numbers were nearly the same. The Wh was 97.5% but the Ah number was...

Sorry to hear some almost smoothbrains literally sabotaged your business for a short period of time. PayPal can be quite PITA when you’re a seller and buyers do such terrible things. I’m honestly surprised ES isn’t banning them since they used ES to defame your business with zero relevant...
