while testing batteries on my Liitokala 500.... two Sanyo's gave me that "Pop" sound and stop registering, I tooked out and was discharging .
Is common that this portectiong arise or could be the charger?
Thanks in advance!
I have been reading that each parallel should have cells within 50 to 100mAh
But in Repackr.com when I usi it, give me in each parallel block on top 2600 and the bottom of the "p" 1800mah ones....
Can you please clarify what im missing :(
Hi All, I wired the two clamp to my 1K GTIL Auto sense, first was reading -neg, then I swapthem directions and know is reading +pos....But..... I disconencted everything at home and just plug a Fan to a wattmeter.... the Fan read was 58watts but GTIL was reading 32-33 This is my preliminar test...
Hi All Experts,
Finally I got my Sun GTIL grid tie inverter with limiter.
Im testing it with out any isolar panel and battery feeding it and.....
I did the serial dual clamp connection and seems to be reading it nicely.
But.... when I have everything disconnected.... I got a reading of 5W...
Im in the process of select a decent BMS and reading through the details some of them recomend to connect the BMS to cell charged to 3.7 instead of full charge...
which is your experience in this matter.

I'm working on a tailor made app to configura battery packs,
It will by a standalone exe then migrated to theweb.:
Im planning to add include IR - initial volt from harvesting - lost voltage from rest - some other variables
Feel free to send me anything you would like to add /...
Im goal is reach to 14s90p on my first battery... I have read that is recommended locate BMS in the middle of the stack or battery to have a distributed load/charge...
This doesnt sound 100% valid on my powerwall baby knowledge.... what is your opinion about this topic ?
I have a question related to BMS amps capacity.
Im building a 14s18p powerwall , lets say that I can draw 5am per P = 90amps (idealy)
But I know that the max charge capacity from the Charge Controller is 30 amps
And the Load will not exceed 20 becuase I will use a 1k GTILv2
I just come accross this 6 cells, JDDL INR, looks a custom chinnesse batt, came on a OEM battery replacement of a laptop.
I havent charged nor test it yet>
I would like to know if anyone have experience with this and it performance on PowerWalls.
I'm still harvesting and studying about secondlife storage....
I'm curious to know how do you determine the each battery cell capacity after grouped and package
so if I have a setup of 2 x 13s8p ... in theory each p shoud have a similar capacity multiplied by humber of rows.... but is...
Me again, trying to absorve as much as I can....
Im charging a battery at 1Amh (Theorically) maybe is getting a bit less than that, and Im getting Temp readings with my temp gun of 47C degrees =116.6F degrees
What is the acceptable max degrees per cell... allowed .. cell is a Samsung...
I just ordered a two CT clamps rated 100A / 50mah ...
... to connect them in series to cover both hots..... and suppously this will allow us to read properly the whole house consumption.....
But I was checking this guy dual ct clamp "Calibrated" and "Adjustable":
no afialiated link...
I got a lot of Arris modem batteries which comes with ICR18650-26F
I have read few lines about these batts....
Those theseare doable for powerwall goal ?
Thanks in advance for the replies
In you vast experience,Does EBL 18650 3000mAh are good for powerwall purposes.... I have seen nom test giving 2500 avg. of 3000mAh advertise...
I would like to know if worth it for powerwall
Any info provided is highly appreciated.
Anyone came accorss with this battery :
DSD ICR18650F - 3.7v 2200mAh 8.1Wh BF10
Can find it on the cell database
stored for a while and came with 2.58v charge from rest... I'm still waiting for my Liilikola
Thanks for any info about these
