What is the recommended discharge rate lead AGM battery.

[gogo]

That's exactly what happened to me, the hill was both steep and long, the motor was only 1000w. 15 all uphill miles was too much for lead for me.

So, you want me to change my story? Change what actually happened to me? My personal experience with lead was short and sucky.

Sorry, I got lazy with the quote button. Here's the part I homed in on:

…I tried that on a real hill, and the heavier I got with lead the less distance I made it up it. …

This is the kind of example that is assigned to be solved in physics classes. Once I took that class, I see things in a different way. Please forgive my affliction.

If I correctly understand the anecdote you refer to, the problem wasn't the source of the 'extra' electricity, it was that your motor already had as much electricity as it could use without becoming a heater, and any extra electricity added only heat to your motor. In this case, any kind of battery that weighed anything would reduce your range, and so would any extra weight of any kind. Going down the hill with LA would be a different matter. :wink:

If the system in your anecdote hadn't already been at its load carrying limit, even lead acid would have increased your range. Having said that, I readily agree with your point that heavy lead acid is a poor choice for hill duty specifically, and in general.
