（Question on DGR 220.127.116.11 Wheelchairs with Lithium Batteries. ）
DGR 18.104.22.168 states for Wheelchairs with removable lithium batteries, the batteries must not exceed 300Wh or if fitted with two batteries for operation, each battery must not exceed 160Wh. What is the permissible battery capacity if the battery cannot be removed? What about for the batteries for other wheelchairs dealt in 22.214.171.124 and 126.96.36.199? (31 Jul 14)
In all cases, with the Wheelchairs with non-removable lithium batteries (DGR 188.8.131.52), the Wheelchairs with batteries dealt in DGR 184.108.40.206 and with the Wheelchairs with batteries dealt in DGR 220.127.116.11, ICAO/IATA has not yet determined on the safe and acceptable limits of the batteries. ICAO/IATA is trying to establish a Wh limit that will provide sufficient power for the user.
