thank you Shawn for all you videos. I've learned more from you in 90 minutes than I have in the last month from others.

Hi Shawn. Can you tell me why you said the Panasonic cells are vulnerable?

Hi Shawn..Thanks for the file...i think theres some formula errors for the Panasonic 3400mah column...the number dun really adds up..thanks forbyour great efforts and i really love watching your videos ..kudos...

Hi Farah, You're right, thank you for pointing that out to me. The spreadsheet has been repaired. If you have any questions about the numbers let me know. Shawn

Where to go to download this app,the link?This looks very useful.

Sure- you can use it for any battery pack, not just with BatteryBlocs. www.batteryblocs.com/the-batteryblocs-calculator/ This will download the spreadsheet to your computer.

Hi Groovy, Sometimes people tinker with it- would you try again and let me know? docs.google.com/spreadsheets/d/1TcDn1ZzePIOEj0Uxsid21hANpiHbP4Ob-MYdyEO-riA/edit#gid=1840194486 Shawn

Will this work with an off grid solar application.... I need a total of about 5000wh. Can you charge with PV panels
@shawname2
@shawname2 6 лет назад
Sure- it will work with any application. My home is off grid and stores power with a homemade lithium ion battery. You will need a charge controller- It will convert the PV voltage to the voltage your battery requires. That way, you don't have to match the battery voltage to the voltage the PV panels put out.

Shawn McCarty what about matching the inverter voltage, I have a 24v system
@shawname2
@shawname2 6 лет назад
The solar panels power the charge controller. The charge controller feeds the batteries. The batteries power the inverter.
@estrellamountain1

ok, but I'm asking about the battery voltage...some of these old off-grid inverters don't accept voltages much higher than the nominal voltage rating of the inverter. For example, in my casita's system, I have a 12v inverter it has trouble with anything over 13.2 v... but because 18650s have a voltage of 3.7v and not 3.2v I think I'd have a problem with overvolts seen by the inverter. Can your blocks be used with li-FEPO cells I think they are 3.?2v
@shawname2
@shawname2 6 лет назад
Hmm, with just 13.2 volts, could you use a 3S configuration of Lithium Ion and charge to 4.2 volts per cell? That would get you to 12.6 volts. For long life charge to 4 volts per cell, 12 volts.... I can make the BatteryBlocs to fit any cylindrical cell.
