Looked close personally at the Venom charger. Instructions that go with it are hideous. They don't tell you that you also have to provide your own balancing cables. 2 boards are included but not like the charging board I have. Just two short boards with an assortment of sockets attached to each. Charger I looked at was new so the cables are either not included or they were missing. Simpler to just get a charger specific for the Yuneec batteries as I don't have an assortment of devices with different types and sizes of cells. Looking more for a charger specific to the Yuneec batteries like the GiFi one but wanting a balancing one at least if not also one that discharges for storage.
