Jump to: navigation, search

To upgrade from 2000X to 2000XR involves using A123 batteries that carry a more durable charge at less than half the weight. Adding balancer for each battery pack. Adding a charger and a new battery cable. The original 2000XR provided a S5P3 pack (5 in serial, 3 in parallel). Using the OMG batteries it is possible to create a S5P3 or large pack from multiple S5P1 pack

Battery Cable

The upgrade battery cable utilizes a male Deans plug, a 5.5 x 2.5mm barrel jack (female charger plug), and two Insulated Female Terminals. This cable replaces the 2000X cable.
