D5 evo smart

I bought the d5evo smart on the 10th of february i only installed it a week back . The evo smart takes 2 bateries where the power supply charge both . Now i have a new product that over charge the one battery so everything heats up . .. now i have to sent back the supply with the pc bord and it will take 3 weeks or i could drive to jhb bcz it has a counter warranty .... i went to buy a jew power supply and ask them to test it before i take it back and the brand new one in the shop test te same that it will overcharge the battery so my meaning is its a defect product and i am sure that centurion are a ware of the defect product they sell because it is a common problem so please before u take it out of the shop make sure they test the power supply or u will end up waiting for your brand new product to be repaired or going to end up driving the parts to jhb so they can fix their defect product while u wait
