I’ve tried to find more specs from the manufacturer but unfortunately, I’ve had no luck.
I think the best resolution for this would be to grab the specs from the 12,000mah and the 5000mah lipos and interpolate the two, to get a rough estimate of some values. Try these settings and carefully watch your lipo the first time it is charging for overheating, just to be extra safe. The lipo is monitored for raised temperature already so it should cut off in the case of overheating.
We will contact the manufacturer again to try and get some solid specs but unfortunately there is no guarantee of when or if they will reply.
I see you added " product alert: Note - this is a generic LiPo battery that is compatible with PiJuice by using a custom profile in the PiJuice configuration software. The standard PiJuice battery profiles may not work as intended with this battery."
Thanks for posting on the forum! Sorry about the delay in getting back to you, it’s been quite busy here at Core Electronics today.
Yes, you can use it with the PiJuice, all of the generic battery brands that are supplied here use the same kind of NTC (thermistor) as the PiJuice cells themselves to my knowledge, and typically when I set them up I put together a custom profile based on how much load my Pi will draw when idle and the batteries specs.
We offer generic cells as well as the original PiJuice batteries here as it provides customers more choice over the capacities that they want to use, as well as getting to use less expensive cells as an option.
We’ve had a few discussions about these batteries before:
Personally, I’d suggest following the 1000mAh profile, and then creating a custom profile below by changing the following settings:
Capactity: 10000mAh (or matching your cell)
Charge Current: ~1000mA (this is due to the type of wiring connected to the battery rather than the battery itself, with a 10000mAh cell with some thicker wiring you can usually get away with charging at higher current, usually around 0.5-0.6C if you want to ensure you have a decent battery lifespan)
Everything else can remain the same, as the type of NTC being used and both the cutoff voltage and max temps should all be quite similar between cells so those values will work nicely. If you have any other questions please let us know. And feel free to shoot through an email if you’d like to organize any returns/refunds, this is a forum designed for discussion about projects and product use/applications for order administration we use our support address. Enjoy the rest of your day!
Yes, basically everything remains the same with these two cells with very slight differences in profile.
Yes, I did, all of the values except for Capacity and Charge Current can remain the same with the variants of cells that we supply. So the Termination Current, Regulation Voltage, Cutoff Voltage, Cold Temperatice, Cool Temperature, Warm Temperature, Hot Temperature, NTC B Constant, NTC Resistance (ohm), OCV10 mv, OCV50 mv, OCV90 mv, R10 mOhm R50 mOhm will all match or can generally be left the same as the 1000mAh profile which you originally linked. For basically all our 1S LiPo such as these ones they have the same type of thermistor and the cutoff voltage for the 3.7V LiPo should still be around 3V (3000mV although personally, I like to cut a little earlier at around the 3200-3250mV range to extend the battery lifecycle as you don’t want to run these cells on low voltage for an extended period of time):
I just logged in and ensured that settings were based off the 1,000 battery profile. I lowered the charge current a bit (as the battery wire’s seem small and the battery may last longer if the current tis lower?).
