			LBC1 (Primary Battery Data) is queried on address 0x18DADBF1 and response received on 0x18DAF1DB.

			LBC2 (Isolation and Secondary data) is queried on address 0x18DADCF1, and response received on 0x18DAF1DC.

Phase 1 41kWh Battery Pack

	2016 - 2019 Manufactured by LGChem, same dimensions as the 22kWh pack and a straightforward bolt-in swap to earlier cars.		2016 - 2019 Manufactured by LGChem, same dimensions as the 22kWh pack and a straightforward bolt-in swap to earlier cars.

			The vehicle includes a plastic housing situated behind the battery pack incorporating a blower fan, and air-conditioning evaporator.

			=== Cooling & Heating ===
			On the 41kWh pack it includes two PTC heaters, one supplied by a 40amp fuse, and a second supplied by a 70amp fuse, theoretically allowing over 1kW of heating. These are relay controlled by the EVC.

			The battery blower is controlled by the Air Conditioning Control Unit. It appears to be wired as a second interior blower (as in dual zone) heating system would be in other Renault vehicles, it has PWM control and a RPM feedback signal.

			The Air Conditioning appears to only be used when the vehicle is charging and the battery temperature exceeds a setpoint.

			The blower is activated in conjunction with the Air-Con or on its own. It is run when battery heating is in operation.

			=== Construction ===
			The battery pack consists of an aluminium alloy base to which the battery modules are mounted. There is a pressed steel lid that bolts on top of the base with a large amount of small bolts. A gasket is integrated into the base and can be reused. The many bolts appear to be scewing in to rivnuts which can be problematic if cross threaded or over-tightened, Renault have a procedure listed for replacing these.

	== Phase 2 52kWh Battery Pack ==		== Phase 2 52kWh Battery Pack ==

	2019 - 2024 (end of Zoe production) similar dimensions to the previous two batteries, but with an additional 4 mounting bolts, and bolts directly to the chassis as opposed to via metal brackets. Can be bolted into original Zoe chassis if you add a plate with two captive nuts inside the chassis rail. Totally different pin configuration on the low voltage connector, and totally different CAN messages so requires a CAN translator. High Voltage connector is the same as the earlier models, wired the same.		2019 - 2024 (end of Zoe production) similar dimensions to the previous two batteries, but with an additional 4 mounting bolts, and bolts directly to the chassis as opposed to via metal brackets.
