Headway 38120 Lifepo4 Power

[sikeston34m]

Anyone else try the larger scale Lifepo4 power?

I used this to power a 180 watt spider lamp earlier during a power outage, running an AC inverter, of course.

8 38120 10,000mah cells configured 4S2P

She puts out 20,000mah and so far, I'm impressed.

Each cell is 38mm X 120mm and are 10C cells. So each cell can give up 100amps continously.

Size reference? See the Quarter in the picture?
