944Thunder Sky batteries
- Feb 5 2:44 PMSearching for Lithium batteries, I came across the
manufacturer's site for these 3.9 volt batteries. The specs for the
100 AH model (LP8581A) show that 44 of these could replace
my Force's 50 AH batteries with space to spare. This would
double my range. The pack weight would drop from 819 pounds
to 291 pounds. This would increase the possible payload from
the current 650 to over 1150 pounds.
On the downside there is cost: 44 of these batteries cost $6380
plus shipping. Battery life may only be slightly better then the
lead-acid pack: at 500+ cycles, far less than NiMH.
Are there other problems with these batteries? 2x range for 3+x
cost is bad, what about current drain during hard acceleration?
