Default A Simple Question About LiFePO4 Batteries

Try the Australian made Fusion brand, no cheap chinese junk. Fusion use prismatic cells, not round cheap laptop cells.
They also have very good internal battery management. They are the ONLY LiFe battery approved for gliders in Australia.
I have quality laptop batteries that are 10 years old, 1500 and 90% charge still.
Its all about the quality, just as a cheap SLA wont last, neither will a cheap LiFe.
