And it will be better if you buy fire-resistant bags to put your battery to avoid fire risk. For the frequency to charge to the battery, firstly, if you frequently use the electric bike, you do not have to charge up to 100% for every time. Charging it within 30% to 80% is recommended for these ranges can extend the lifespan. If you need to ride it long distances, you charge it up to 80% level. While if you use it in a short distance, more than 30% charge level is appropriate.
