||||||||||
 |
It is lighter - the SLA cells weight 5Kg compared with 3.2Kg for NiMh |
|
It goes further: only 65% of the capacity of SLA can be used (before the output drops to 20 Volts). 90% of the capacity of NiMh can be used - increasing the available power to 200%! |
|
It charges faster: controlled fast-charging cuts typical refresh time to 3 hours |
