TP5000 4.2V and 3.6V 1A Lithium Battery Charging Board Charger Module
Suitable for LiFePO4 cells, also suitable for Li-Ion / LiPo / LiFePO4 6V solar charging (because it allows higher input voltages).
Review: http://lygte-info.dk review/Review TP5000 charger module
It would be good if there were a board such as this that would also cut-off the battery when under discharge it falls to 3.3V or 3.0V, the internal cutouts on a lot of Lithium batteries let the battery go down to 2.4V.
Also be aware that according to the review this board will charge a Lithium battery that is completly flat (0V), not sure that is safe.
I agree, but I have not yet come across a module like that (and for low price).
Something like this popular charging module but then suitable for LiFePO4 would be nice.
No bargain but serious LiFePo4 charging for outdoor nodes: https://www.tindie.com/products/xorbit/lifepo4weredsolar1/
Nice product, but for $17 + $14 shipping = $31 is not a bargain indeed.
For those looking to use LMR400 or it’s variants.
