Hi to owners of the Oxygen scooter ( or any other electric scooter ) The main problem with the sealed lead acid batteries is that they do not like deep discharge and have a terrible range especially if you live in a hilly area. The only battery to go for is the Li-Ion Lithium batteries.
I converted mine from Lead acid and fitted a Lithium charger and BMS System and now enjoy a 90Km range on the Lithium Batteries
The chap that has these kits ( not inc battery as you need to get locally) has two more and the cost is 150.00 US or 100 Euro plus postage which is a great price when you consider the Charger alone now is 800 US.
They have come out of the Oxygen Cargo scooter 36 volt as the scooters were converted to 48 volt 120 km and they are in full working order.
So dont give up CONVERT to Lithium and throw our the lead acid
