I have two electric scooters that run on two 12 volt 15 AH (I assume that’s 15 amps) batteries for a total of 24 volts and 15 amps. These batteries are sealed lead acid. Each scooter has a 500 watt motor and a 24 Volt fully potted Smart Power Microprocessor with relay protection. The scooters can go a maximum of 12 miles (depending on the weight of the rider). I weigh about 200 pounds (twice as much as my son). The scooters can hold a maximum of 240 pounds. My problem is that when I go riding with my son, I can only go half the distance as he can. We have to switch scooters after a few miles so that the one I was originally riding can make it back to the starting point.
Consequently, I’ve asked three electronic technicians that I know to give me suggestions on increasing the distance of the scooters. Two of them told me that I could use two 12 volt batteries with more amps. I was instructed to connect the two batteries in series and then connect the series in parallel with the original batteries. The other technician suggested that I buy batteries like the original ones and use a toggle switch to select the additional batteries when I need the extra power.
Subsequently, my question is "which suggestion is better?"
I like the suggestion of the first two technicians. However, I’m not sure what kind of 12 volt batteries with higher amps to buy. One of them suggested Lithium Ion batteries. Unfortunately, the batteries would cost more than the scooters! Therefore, I’ve been searching for less expensive batteries. I know that car batteries are 12 volts with high amps. I saw one with 12 volts and 450 amps for only $59.
Can I use 12 volt high amp car batteries with the scooters? If I can, do I need two batteries or can I use one? The reason why I ask is because I only have room for one battery on each scooter, but I could possibly mount two. Can I connect these batteries in parallel to the original 12 volt 15 amp batteries? Can I recharge this setup with the 24 volt 1.5 amp recharger that came with the scooters? Should I disconnect the original batteries since I can’t go far with them and use only the additional batteries?
I would really appreciate any answers and suggestions that might help me. Please keep in mind that I have very limited knowledge in Electronics.
