We use one that does not appear on the list. Came directly from DeltaQ, as we use a pack that finishes charge at around 63 volt. But the last 3 volts are at a much reduced charge rate, otherwise the charger would be over rated. But it works ok for us. It also has the issue that the charger will give a fault code(but still works) if it the pack is connected to he charger at over 60v. Voltage has to drop below 59v and then it resets. We also re profile the cutback table in the Sevcon to reflect a safe use of the pack, cutting back in a series of stages, and cutting back at the top end (deals with overcharge from regen when charged) .
