hmm.. I don't know what monitor or driver you have but mine doesn't do that.

Piano, I agree. 5200 is great.

Northstar also makes a partial state of charge lead based battery. The specs mention -40.

pianotuna - if a person had room to series 3 of the Firefly 4v batteries you would have 675ah useable at 50% discharge (1350ah x 50%) for 3900 cycles for C$3100 ... and cold weather capability?

When you series connect you add voltage not capacity. Three of the 4V batteries, series connected would result in 450AH at 12V.

Yes - correct - thanks

I can live with 5200 cycles at 50% discharge.

Interesting chart. One heck of a drop off in cycles between 30% to 40% and 60% discharge for Firefly.

GordonThree,

Ah. I was interpreting "light discharge" as low current--not as depth of discharge.

Light discharge to me, from my marine jar days was 20%. 50% would be just fine.

Trying to visit the Sacred Sun battery website, I get this.

How do you get the "light discharge" information?

The graph seems to indicate the biggest cycle life gains for applications under 50% DOD.
