(Suitable Wattage of Motor: from 250 Watt to 2500 Watt suggested.) 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 it into our battery module) and contactor. Besides the basic functions such as over charge/ discharge,over current, short circuit, over temperature and balancing, Our BMS owns the following features, 1. Master-Slave architecture makes the 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. OEM orders are available 2. Superior quality and cost-performance ratio 3. Tags, plugs and connectors are available 4. We could design and produce the battery pack with aluminum alloy shell and assembly procession for customized configurations is available (we could design and develop Li-ion battery according to your product work performance & structure appearance) 5. Bulk pack is available Lithium ionbatteries are common in consumer electronics. They are one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defense, automotive, and aerospace applications due to their high energy density. Li-ion batteries are lighter than other equivalent secondary batteries—often much lighter. The energy is stored in these batteries through the movement of lithium ions. A key advantage of using Li-ion chemistry is the high open circuit voltage that can be obtained in comparison to aqueous batteries (such as lead acid, nickel metal hydride and nickel cadmium). Long battery life: 1000 plus recharges Ultra light and small size Super high discharge rate means more power. Super long range It never explodes! Peace of mind for you! No Memory Effects Maintenance Free: only need to charge it once every month if you are not using it 51.8V/52V 50AH 2500w 1000W Lithium Battery with PVC Case,50ABMS and 58.8V 2ACharger: Parts included: 1.51.8V 50AH 1500W Lithium Battery with PVCcase 2. 50ABuilt-in BMS board 3.
