How many w/h in your batteries?

[Mathurin]

Allright, so in The "Brave Combo" Lithium Pack topic, Safe has asked how
much juice people get out of their batteries in real life. I thought the question
deserved a topic on it's own, so here it is.


For myself with three 12v 12ah SLA bricks, for the few times I drained them
all the way I was able to get between just under 8a to just over 11a out of
them. 300-400w/h? But since they recommend to stay below 50% with
theese batteries, I guess the real range should be limited to 4-5.5amps, or
150-200 w/h. Not ultra impressive given the bricks weigh 9lbs per...

Current bike - Realistically about 700 watt hours. (SLA - 3 @ 38 Ah)

Next bike (s) - Either 700 watt hours or 1400 watt hours depending on how much money I'm willing to spend.

Good new thread topic...

2,500 watt-hours, 80% DoD available reasonably...so 2000 watt-hours.

I ride a 20-mile bike path trek with hills a few times per week. I pedal along at about 15mph. There's about 2 miles of on-road, 25mph no-pedal riding. During this ride, per subpack pack voltage drops from 4.15V to 3.94V. So I'm edu-guessing I'm consuming about 500 watt-hours, or 25% of available energy. A drainbrain would be a nice upgrade to the analog meters I otherwise prefer.

Hmmm... let's see, I have four 13ah Hawkers. That's about 624 w-h at a .1c rate. But I suck power a bit faster, so realistically, I can get maybe 400 w-h out of them on a nice hot day. Less than 300 w-h on a day like today (cold). These are estimated numbers, not measurements.
Those weigh in at just around 50 lbs.

I've gotten over 9.7 AH out of my ebikes.ca 24V 8AH NiCad pack. Assuming a constant 24V, that comes to around 230 WH. That was in the summer. In the winter, I'm getting a bit less.
