    adjustable Cheap Chinese Active Balancers

    Mass Cap Testing ?

    same here just with LiitoKala Lii500 instead of Opus. In combination with some XTar VC8 for 0,x V charging, and some cheap charger for precharging so the LiitoKala can work faster

    Hello from Germany/Poland

    and that's even big. But 1.000W or 1.500W is extreme for an ebike. You know there is a limitation by law to 250W continous output and 25KMh in Germany?

    Looking for a capacity tester 1s10p lithium battery

    Hidance DL24P-Plus It's an adjustable electronic load with up to 20A. Round about 45USD on Aliexpress. They also sell a version without the huge CPU-cooler on it for about half the prize, just add an old cooler which is laying around.

    Connecting grid tied inverter

    As I know so far there are three different types of grid tied inverters. 1. just inverter, no solar charge controller -> AC is only for output, the input comes from batteries, like the GTIL2 (I think you can choose between batterie and solar but not both at the same time) 2. inverter with solar...

    18650 Garden-Powerwall with 50KWh in Germany

    I solder the fuse wires to the cells with a cheap solder-station from eBay. For me 370°C on the positive side and 390°C on the negative side seems to be perfect. At low temperatures about zero degrees at my garage where I am working you can add 5°C for soldering better to solder the fusewire...

    18650 Garden-Powerwall with 50KWh in Germany

    in the meantime the mounting system is done and installed time to build the packs. It's a recycling of the "bad" cells between 1.500mAh and 1.900mAh the good ones above 2.000mAh are sorted in 50mAh parts, this are only sorted in 100mAh ones. But I think that in the planned 100p packs they...

    JkBMS B2A24s-15P Active Balancer Question

    Almost. There are three requierements for the bms to start: a minimum of 40V between the first balancing wire (b1) und the last (b+). This is the power supply for the bms itself the big "B-" wire must be connected to the battery minus a short 5v impulse between B- (+5V) and P- (-5V) to start...

    18650 Garden-Powerwall with 50KWh in Germany

    Yesterday I tried to build a mounting system as HB uses. First idea: to find a manufacturer who can build this and uses the CAD files HB provides in his thread but then I decided to build it for my own out of an old 2mm metal plate first I cut a template which I can use for the plasma...

    how do you bend the Monting plates? Or do you buy it ready for use?

    HBPowerwall (Official)

    the download link of the CAD files for the mounting-system seems to be down, maybe because of the new forum software update? Does anybody can provide the "normal" 80p version CAD files? I would like to ask around in my region if someone can do this kind of work

    got a notice from ebay.18650 cells prohibited.

    I am using eBay since 2004 very often, it's my primary shopping adresse (don't like Amazon) and I noticed this change too. I guess it's the point, that eBay is nor more a platform for private people as it was in the beginnings. You won't find a mentionable number of "1€-auctions" or of private...

    150W High Current Tester

    just 2-wire meassuring, will not work. You have to look for 4-wire voltage meassuring. With this electronic loads you have just the choice between the one above (I ordered 3 times and didn't get one, so no option for me) or this one: https://de.aliexpress.com/item/1005001458325206.html...

    18650 Garden-Powerwall with 50KWh in Germany

    checking the IR cells above 70 mOhm were pushed a little bit out so after checking all the 150 cells I can sort out the bad ones and after IR test the "statistic" is going even more bad. So last week I phoned a few of my suppliers and luckily one of them had a early christmas present...
