Did you pay any taxes, tariff, duty or brokerage fees on top of the $1132
I was told yesterday during our long chat (3 hours+) that shipping would commence on Feb.05 and that shipments are being queued up according to order date. Now just my assumption but I think that orders have been piling up over their holiday period and as such there will likely be a backlog. I think it's safe to say that anything ordered in the past two weeks will be backlogged for a little while.Look Gang, no bullshit. I have now tested 4 of 8 of these cells for capacity and all are scoring between 98-104 % capacity. I can only say I am so impressed that I am ordering 8 more cells. Will be quite a delay with the corona virus crisis but will get eventually.
OK here are some of my pictures and videos.
Can you please share exactly how you charged / discharged them?OK Results on first Cell Capacity Test: 105% capacity, 294 AH for the first cell tested. I am going to test another cell starting tonight.
How do you decide when it's fully charged?Fully charged to 3.65 volts
I apologize for asking, I do not want to question your knowledge, I want to learn from your experience.I have been into lithium for some time, Built large banks starting 5 years ago for sailboat...
How do you decide when it's fully charged?
As soon as the voltage first hits 3.65 volts?
Or when the current drops to 0 Amps?

Yes when the amps drop to 0.1 amps at 3.65 V then they would be considered fully chargesHow do you decide when it's fully charged?

I get 187.50 USD/kWh if using 12 volts in the math$175.78 / kWh
New cells.
To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:Yes when the amps drop to 0.1 amps at 3.65 V then they would be considered fully charges
Just asking are you making a specific point about this discussion thread...?To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:
- Keep the battery temperature under 45 Centigrade (under 30C if possible) – This is by far the most important!!
- Keep charge and discharge currents under 0.5C (0.2C preferred)
- Keep battery temperature above 0 Centigrade when discharging if possible – This, and everything below, is nowhere near as important as the first two
- Do not cycle below 10% – 15% SOC unless you really need to
- Do not float the battery at 100% SOC if possible
- Do not charge to 100% SOC if you do not need it
Don't charge to 3.65.Just asking are you making a specific point about this discussion thread...?
