Thanks for the advice Greg, I was a little worried about the current delivering capability of lithium. I have the battery current on my controller limited to 450A max. The sinopoly cells I was looking at has 3C (300a) as the max continuous current with 5c (500a) permissible for 10 sec bursts. I'm not sure how long they'd actually last in my vehicle. If only we could all have 300v AC systems with tiny current requirements
My wife is dead against the idea of buying new batteries, even though I bought her a (secondhand) Toyota Prius last week. She just doesn't understand Batteries are eyewateringly expensive though. The price of one battery pack could get you a really good used car and that's how most people look at it.
Edit: Looking (mournfully) at the datasheet for my 160aH Sec Red Tops
Stopping at a cell voltage of 1.8V :
20hr rate (8a) 160aH
1hr rate (89a) 89aH
30min rate (141a) 70aH
So I guess from my pack at the moment I probably can't get much more than 70aH thanks to Peukerts effect. The red tops weigh 611KG the 100aH Sinopoly would weigh 156KG very big difference! Anyone want to buy one of my kidneys?
