I'm really getting interested in the new lithium batteries that are coming out, especially for use in solar-charged feeder and camera set-ups. My only concern is the charging as from what I understand, lithiums are more sensitive to charge voltages, especially when cold. To charge in the cold (the ideal feeder/camera situation), there has to be some battery management system or warmer that managed the temp of the battery for successful charging.
Since the batteries are coming along, surely the charging systems are too- but I haven't seen any for what we would use them for. Any intel on that?
The charge/overcharge/over-discharge electronics (BMS)
is built-in to the batteries like the one I linked above in the 2nd post!
They are not 'raw cell' batteries (much like a SLA is) - way better and managed per cell!
That kind is truly plug-n-play for SLA replacement but even better, even in high-current applications like computer UPS units, even for multiple batteries.
The LiFePO4 cells that are inside the battery unit are designed for use between -20°C to +70°C (charge or discharge).
This video shows a sample of what's inside these kinds of batteries:
