Ordering the Batteries
It is time to order my batteries. I’ve selected the CALB CA 180. This is a new product that recently became available. It will give the same range as the previous battery (100 miles per charge), but it can deliver more current (1800 amps in a 10 second burst and 540 amps continuously), and it lasts 3000 charge cycles.
Within the Lithium category, lithium iron phosphate is at the lower end of the range for current rating and energy density, but the trade-off is worthwhile – better thermal stability under high load reduces the risk of a fire, and longer lifetime. The only real downside is the price.
