Waterproof Grade: IP65 How do i know if the mid drive conversion kits will fit my bike ? The Mid Drive Kits are designed to fit bikes with a 68mm (2.68 in.) or wide bottom bracket shell and 35mm inside diameter. This encompasses the vast majority of bikes excluding some newer high end bikes with an Integrated Bottom Bracket, and Fat tire Bikes with a 100mm wide bottom bracket shell Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by. Does not use or leave the battery near a heat source as fire or heater Use the battery charger specifically for that purpose when recharging. Do not reverse the position and negative terminals. Do not connect the battery electrodes to an electrical outlet. Do not discard the battery in fire or a heater. Do not short-circuit the battery by directly connecting the positive and negative terminals with metal objects. Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc. Do not strike, trample or throw the battery. Do not directly solder the battery and pierce the battery with a nail or other sharp objects 1. Cells -A grade cellsto make sure batteries inhigh and full capacity 2. Protection -Dual IC chips, that can anti-short circuit, anti-over charger, anti-over current, anti-overload 3. Compose Type : Injection Technology tomake battery more stable. 4. Certifications : CE,UL,FCC, RoHS, ISO9001 5. Long life cycle, No memory, environment friendly. Our BMS consists of Master BMS Circuitry (we named “BMU”), Slave BMS Circuitry (we integrate itinto our battery module) and contactor.Besides the basic functions such as over charge/ discharge,over current, short circuit, overtemperature and balancing, Our BMS owns the following features, 1. Master-Slave architecture makesthe system flexible; 2. Two level warning makes maintenance easier; 3. CAN2.0 and industrial level electronic components make system reliable; 4. Contactor makes high rate charge & discharge feasible; 5. Periodic insulation measurement makes personnel safety possible; 6. Host can control the system easily; 1. High energy density 2. High working voltage for single battery cells 3. Pollution-free, environment friendly 4. Long cycle life; It extends its cycle life up to 800 cycles 5. Capacity, resistance, Voltage, platform time consistency is good 6. Simplifying battery management system (BMS) and a battery charger 7. With short-circuit production function, safe and reliable 8. Factory price & High quality 9. Fast charging 10. Light weight, small size 11. Large overcharge tolerance and safe performance 12. Self balance 1.Light electricvehicles: such as electric bicycle, golf car, small-scale electric flat car, forklift, cleanness car, electric wheelchairs 2. Large-scale electric vehicles: such as bus, electric car, tourist car and commix car 3. Electric tool: electric drill, electric saw, lawn mower 4. Remote control cars, boat, aircraft, toys, 5.
