It has been heavily used and I got it right after the release usually 2 full charges a day but at least one.
I remember him saying that they would lose their programming now that you mention it.
Mine was one of the ones that pulled out of the case and iirc the battery is connected by two wires soldered onto the board and then soldered onto that battery.
It would be easy to replace if you have ever soldered. too bad it would need to be recalibrated.
Would it be a bad idea to solder in the new and then remove the old batt so It never completely disconnects from power? Or would that cause a surge to burn the board?
Lots of stuff there, perhaps I can offer some insights?
First off, that's a lot of cycles (recharges). 300 is a common estimate given reasonable treatment. It could well be getting worn out?
Yes, they do lose programing if you power completely down, but you have to be able to build them and there's no programing port......so they boot up just fine and you need to do a discharge way down/fully recharge cycle (one time, any time) so the flashing part of the charging light works right. That bit, the flashing light while charging, is the only calibration in question, temperature calibration is in hardware it seems (2.2 Volts for low temperature, 2.0 for high), so no problem there really.
Yes, I've done it. Earlier today in fact. BTW they do charge OK from USB connectors with less power, it just takes a lot longer using a .5 Amp one than the 3 Amp unit VB send us.
You're memory is a little off. There are 3 wires, not two, and they end in a handy connector. If you had the replacement battery and weren't too shy with tools you could do it, but it's pretty frail in there it's easy to break a heater or sensor lead free from the PCB and you then be up the proverbial creek without excellent soldering skills to fall back on.
Also soldering such live batteries in is very far from "easy to replace if you have ever soldered" it is, in fact very dangerous to do. There's a LOT of energy on tap in that battery, a little slip and the sun could come up in front of you....or you could fry something nearby if the wire, solder or iron went the wrong way. A job experts sweat over and avoid (like by using connectors.....) if at all possible.
Yes, you absolutely remove one battery before soldering the other in in such cases, you don't want strong fighting weak there as you watch.
I'm sure in the fullness of time demand for batteries will net a solution. The maker or some savior of the faithful like Pipes will rise to meet it.
Here's a shot of the back of the board and the battery. You can see the cable and connectors with the 3 wires (white, black and red).
When the time comes, I bet we find a solution.
