Well that’s a good question. It seems like that would be a simple solution, right? Here is why we don't suggest connecting 2 independent battery packs together for any 3 wheel scooter.
There will be differences in capacity and voltage between different eco friendly electric scooter batteries. Putting batteries in series for electric scooters for adults results in an unbalanced state between the 2 (or more) batteries at all times. One of the battery packs will be consistently over charged and one consistently over discharged. This creates instability in the electrical continuity during all charging and discharging cycles and reduces all of the electric scooter batteries’ capacities to hold energy. This technique sounds good in theory, but it significantly reduces battery cycle life. It is important for 3 wheel scooters to remain a simplified hardware-based system for easy maintenance. Connecting 2 or more high technology battery packs together requires a significant amount of internal computer hardware and software. The software to manage the battery series would complicate the system and require continuous software updating to operate the batteries properly as they age in operation. Installing larger individual battery packs beyond the existing size and weight would exceed IATA, FAA, TSA and IACO capacity regulations for commercial air travel. Answer: A single battery pack for any 3 wheel scooter is the best choice. The single BMS powered battery pack in your Triad electric scooter for adults manages the power for resistance under load and weight capacity, manages voltage discharging and self balances the cells during operations. The Triad battery is designed to be lightweight and swappable, so a second 6 lb. battery can be carried in the front basket and swapped into the battery compartment quickly for additional distance. We recommend carrying the spare battery in this storage bag to keep it cool in direct sunlight. Learn more about Triad Electric Vehicles automotive grade electric scooter batteries.
