| sixwheeledbeast | Hmm, my N900 seems to want to charge forever but never gets fuller than half way. | 12:03 |
|---|---|---|
| CatButts | I've been pondering mating my N900 with a cordless drill battery pack | 12:07 |
| CatButts | I've got a bunch of 18650 and related lying around | 12:08 |
| CatButts | maybe I can DIY a battery pack | 12:08 |
| CatButts | sure, N900 will be thrice as thick, but who care | 12:08 |
| sixwheeledbeast | I'll buy another polarcell if it is that battery. I have never had those symptoms before tho. | 12:22 |
| CatButts | why buy, when I could put to use all these batteries I reclaimed from laptop packs? | 12:34 |
| CatButts | although, this also means I probably need circuit | 12:34 |
| CatButts | I think this is what happens | 12:35 |
| CatButts | N900 charging circuit attempt to do CC/CV for the battery, OR, battery have internal circuit | 12:36 |
| CatButts | but if I replace with battery pack, which will attempt to load ballance and maybe CCCV | 12:36 |
| CatButts | maybe bad idea to put two CCCVs in series | 12:37 |
| CatButts | also, I have to lie with resistor on third battery pin, the appropriate capacity(which probably limits what capacities I can have) | 12:37 |
| CatButts | haha, the N900 is as long as 6x cells are wide | 12:39 |
| CatButts | or 4x if you don't cover camera and sd card | 12:40 |
| CatButts | alternative is to feed it via USB, then that simplifies problems with managing batteries | 12:41 |
| CatButts | but now I have USB occupied | 12:41 |
| CatButts | and need to dummy the internal battery | 12:42 |
| sicelo | And USB cab be fragile ... | 13:18 |
| sicelo | *can | 13:19 |
| CatButts | that too, unless you have one of those flat connectors, like those used for adding wireless charger antenna | 13:33 |
| bencoh | which reminds me I need a new polarcel | 13:41 |
| sixwheeledbeast | Well after spending all night on a NOKIA wallcharger it charged to half way. I have left it plugged into USB most of today and it's full charged... interesting. | 15:19 |
