Hi guys! Im new here and I came because I’m a big problem.
I bought this board two weeks ago, and it goes fast (15mph) for about five minutes and then speed starts decreasing (3mph and lower). This board is equiped with 2 x 7AH 12v Lead-acid Battery. I thought that the problem was there, so I changed both of them and the problem persists. I thought of buying 2 x 9AH 12v, but then I thought that maybe it was a problem from the Lead-acid technology itself.
I just read this: Additionally, discharge chemistry of a LiFePO4 battery allows the motor to run at top speed constantly until the battery is exhausted, compared to the initial high current from an SLA battery which quickly tapers off as it discharges.
Is it true? Or should I try with 2 x 9AH 12v Lead-Acid?
Thank all of you!
