Hi, I added another 12Watt 12Amp battery to my 36 Volt 350 Watt 3 Wheel EW-18. It went up in speed from 14mph to 20mph. The only problems I have so far is that I had to extend the battery cover using the top 3.5 inches of a hard shell from the inside of a cooler to fit another battery in the compartment. I also have to disconnect one of the batteries to charge 3 then connect it back and disconnect another one to make sure all four get charged.
Would getting a 48 Volt Charger fix this issue?
Will my 350 Watt motor handle all four batteries and the 20mph speed for the long haul?
Should I consider getting a 48 volt controller to match to charger if I do upgrade?
Then, last of all, should I go ahead and get a 500 Watt front wheel hub motor to be safe?
Also my brake on the front wheel is getting stressed slowing down from 20mph. is there a rear brake option for the scooter below? I do not mind putting a little money into it. The frame is solid. Thanks, Andy
Sorry, I mean a 12 Volt 12 Amp Battery.
Thank you for your thorough response. I will be sure to only use the speed now and then. If the hub motor burns out then I will upgrade it to a 500 Watt but until then it seems to handle the extra battery power. I will price a charger on ebay unless you have one for sale. Thanks, Andy
