You will be probably better off using Bluetooth rather then WiFi. Onyx tablets are notorious for consuming lots of power while on WiFi which cancels the advantage of an E-Ink screen. Either Onyx is using cheap hardware or don't care to optimize the code.
With 12.3-inch Pixel Slate you can achieve 12 hours of giging when using Bluetooth only with screen at 50% and in sleep mode while on breaks. If more power is needed it has a quick charge.
Using 4 Slates in 1x Master and 3 Slaves and with Airturn BT-105 which is based on Bluetooth 2.1. Turning pages for all 4 tablets with one and only page turner - exact/same bar numbers on the page are must.
Hardcore Master/Slave mode. Holy grail for leaders. Less powered gadgets to care for.
Can't thank Mike enough.
