I took a look at the ecosmart controller and it says it has a maximum current of 30a. If I have 3 12v 12ah batteries, what kind of problem would that serve?
Also, would I be able to add that controller to a e300?
Hmm okay, makes sense! One other thing. What would be causing my ecosmart to slow down around 34v charge? I have a voltmeter and it goes to about 41 fully charged, but when I am riding it really slows down when it hits 34? I weigh 190lb. Also the wheel moves fast if I lift the scooter. Is something broken? My wiring off?
I have 3 12v 12ah batteries, stock controller, and a 36 Volt 500 Watt motor.
Thinking about moving over all that to a e300 and buying some parts from you guys to tune it to fit the new motor and batteries
When the battery pack reaches 34 Volts and the motor starts to lose power it is telling you that the battery pack needs to be recharged soon.
It is normal when the wheel is in the air for it to spin faster than when it is on the ground. That is the nature of brushed electric motors that they spin faster with no load than when they have a load on them. It does not indicate that anything is broken or there is a miswiring.
That makes so much sense!
So if I am planning on adding that motor to a e300, with 2 12v 12ah batteries. What motor sprocket should I buy to help go up hills best? I am probably going to keep the stock chain and wheel sprocket. Also, what kind of run time am I looking with this? Would it be worth upgrading to 36v? My commute is 1.2 miles each way, 1 big hill, but can walk that if need be.
Starting to think my ecosmart is dying to quickly. 36v, 12ah each. Runs for like 5min... Would this be due to the batteries being dead? The voltmeter reads 44v when charged though.
How do I test if the batteries are still good? So I can decide to buy new ones for the e300 or not.
I'm assuming two of the batteries are bad. If I buy 2 batteries from you guys, will my third battery (bought it 3 weeks ago, charged like 5 times) need to be replaced too? Or is it still good?
