Slight clarification. The OP asked about a panel config rated for 21.7a - e.g. 2p. But the charge controller unit has a 18a max input. I''m not saying the panels would produce more than 21.7a but that they could produce up to 21.7a if

But the "Trustfire" in my DIY bluetooth speakerbox were a flop and my China batterie 18650 test - 508.800mAh in 62 cells showed that it''s the same with other "brands". So I decided to go with used cells from major brands. I''ve done some researches on the internet where to get used 18650 batteries.

a spreadsheet for 18650 mAh prediction? | Second Life Storage

The life cycle is not a linear line. It''s more like a curve. Without knowing where at on the curve in life cycles, you can''t predict how many are left based on the mAh the cell charges to. There are many cells that have had an easy life, gone through 100''s of cycles, and still perform 80% of their rated capacity.

The cells are repurposed 18650''s from laptops LG''s, Sanyos, Samsungs, Panasonics and Sonys. Yes - in theory 4.2v * 4 = 16.8 but at 4.1v max charge (16.4v @ 4s) you''ll have longer life + good power and the voltage will pull down a bit when load is applied. Reactions: Wolf. B.

How to Properly Use 18650 Battery Pack Builder?

I have a few hundred Headway LFP cells that I tested for capacity and IR. I want to make some 4S battery banks for car audio. I would like to make some different ah configurations probably from 16ah (2P) all the way up to 96ah (12P), but for now let''s assume I''d like to just make some 48ah...

18650 vs other cells?

Regular 18650''s won''t discharge as much as Vape batteries, and that''s actually a good thing. When you have 100 cells in parallel, you can easily hit 100A with ''old crap'' @1A each. With Vape batteries, that could be 2000A which is overkill and I''m guessing that Vape batteries don''t last as long as 18650''s but I could be wrong.

Congratulations on the battery acquisitions! I''ve gone the 18650 route + solder myself and really enjoyed it. My home, 4yr-old, off-grid (with grid-assist) system is individual components - e.g. Midnite Classic 250 charge controllers + AIMS Inverters + APC UPSs + junction boxes + ABB Sace shunt-trip + Midnite Solar breakers + lots of wire.

I''ve actually had good success bringing 0v cells back to life. I first started by parallel''ing a good with a bad for 20 seconds, then on the D4. End game is to feed 100% of house solar to the grid and use second system for household usage with the added benefit of having power during outages. I''ll have to look at grid backup and battery

Mixing 18650 capacities

So I have over 2000 used 18650 cells. I have capacity tested them all and now have a range of between 1200-2000mAh. The thing you need to take into consideration is what was the cells capacity at the start of its life, and what is it now. If it''s more than about 25% drop, then you probably don''t want to use it. Original 3000mAh Now 1700mAh

Samsung ICR 18650 26D Panasonic CGR18650E The Samsung cells I have had very good success rate, most are testing to be over 2500mah, so practically new. The panasonic cells come in second. Their cells have tested every single time to be above 2000mah per cell, with none going below that. The sanyo cells come in third.

18650 parallel cell matching | Second Life Storage & Solar

This is the method I used for my second ebike battery. and all the Samsung ICR 18650 26F cells were all in one parallel group. all cells were above 2000mah, although that was all I had guaranteed. Some cells were 2200mah, 2300mah, a few 2500mah. My theory goes that each parallel pack will only charge to what it will take in, and then they
