Hi BFL13,
This is what I've gleaned so far:
They can be discharged to stone bone dead 620 times without dying. After those 620 cycles, 80% of OEM capacity remains. They are about 1/2 the price of LI. They can be used and charged at -45 c to +65 c. (-49 f to 149 f)
At 50% discharge cycles are 2800 (80% of OEM left)
At 80% discharge cycles are 1500 (80% OEM left)
They can be draw on at a rate of 9C for 5 seconds.
They do not need to be recharged to 100%, but once a month a full charge is recommended.
From the seller:
“This battery has 1200 Watt Hours of storage.
You can access 100%, but it is recommended that you do not regularly discharge over 80% because it will shorten the lifespan of the battery.
At 80%, the usable capacity is 960 Watt Hours of storage. Max peak discharge is, (for the 100 amp-hour) is 900A (5s) at 25 degrees C.
Constant Amp discharge rate is 320A (about 5 minutes until the battery is fully discharged). For charging the rate is .25C (4 hour) charge rate (25A for 1 100Ah 12V battery).”
The only negative is weight. The "best buy" is currently the 100 amp-hour battery."
