Well, when I look at "Elite Power Solutions" 100AH "Package" here
http://elitepowersolutions.com/produ...roducts_id=164 you get the batteries plus a matching charger for a price of $3,225.
Now, if you go to the 200AH
http://elitepowersolutions.com/produ...roducts_id=236 your up into some big bucks pricing.....like $6,895...
..for that one.
But.....if I read their chart right
http://elitepowersolutions.com/docs/...vs%20Speed.pdf and I set my controller to only give me say....a top speed of ten-mph, I should get well over 100 miles (according to them....200 miles) of travel out of one charge. And that's with the 100AH pack. Now, if that's the real case, then the money spent is probably worth it.
But again, I dunno how temp's such as 15 degrees has upon this. But even if that cut's the drive milage to 100, that's more than I'm going to go in one day. Other factors such as how much "stuck in the mud" energy will be consumed, and "how far is this mountain to the top" factor is also a consideration. In addition.....is the 200 mile rating....is that bring the battery down to the "brick" level where it's now worthless? Or is that where it is at the "must be charged now or it will be a brick" level?
