Not sure what you mean. It’s always been great that he comments in the forum and will give us information that hasn’t yet worked it’s way into Framework’s github. And impressive that he’s still able to find time to do it, despite being the CEO and I imagine having a lot of other things fighting for attention. I think many on the forum do notice.
If you mean that batteries have to potenial to be hazardous. Well, a lot of things are hazardous if you’re careless. People have the right to use, fix, and repurpose the things we own. Information about the products we’ve paid for should not be locked away. Or worse, artificial electronic restrictions put in place to prevent repair or reuse. Like Apple’s ‘parts pairing’ lockdown scheme.
At some point you have to warn people, and then treat them as something of an adult. Not everybody is, sure. And sometimes you gotta do something and cause issues. But if you’re so worried that ANYTHING bad is ever going to happen…nothing can happen.
I figured out that the dell latitude 3310 battery connector cable (part number VJMM0) has the same ACES connector as the oem battery but is on a much longer cable and is only arround $10
@Ivars_Pepsons My life unfortunately gets completely overtaken by work for large chunks of the year, but to answer your question, the one cable I made used a similar connector to the OEM connector on the mobo side and a connector I desoldered from an old Thinkpad motherboard for the battery side. Very janky but it works. I’ll probably order some of those Dell cables, though–thank you @djangorb–along with some appropriate parts for the battery end from aliexpress.
I did build the cable and it works perfectly. I got the dell cable from ebay and for the battery connector I bought a Lenovo LS-B093P battery connector board, also from ebay. I then just cut off the plastic pin and soldered the wires from the dell cable to under side of the Lenovo PCB, no de-soldering required
Looks like several laptops use connectors that may be compatible. A few even come on cables. HP ProBook 450 g2, g3, Acer aspire. But it looks like the Acer Aspire is the only one out of those that don’t leave one pin unconnected. ebay search
After 100-ish cycles, the charging voltage downgraded from 17.8V to 17.6V, leading to a sharp 6% drop of battery health. The same problem occurs on 55Wh(downgraded from 17.6V to 17.4V) and 85Wh batteries as well(note the “Desired Voltage” and current voltage at 100%).
By modifying the BMS to set the charging voltage back to 17.8V(17.6V for 55Wh). We can solve the problem once and for all and slow down the battery degradation on all models no matter which mainboard you are using.
Just out of curiosity, why do people wish to connect the FW16 85w battery to the FW13.
It is a smart battery, so one should be able to connect any smart battery out there and not only the 85W one.
I have a modified EC code so that it reports the battery temp. The battery actually gets pretty hot when charging / discharging so be careful it does not get too high and damages it. The EC has some code that prevents charging if it gets too hot, but the laptop fan is not triggered by the battery temp, only the cpu,gpu temp.
