AT(i): Tenergy Li-Ion 18650 14.8V 4400mAh PCB Protected Rechargeable Battery Pack with Bare Leads

Features and Benefits

• High quality 14.8 V 4400mAh Li-Ion rechargeable battery pack with bare leads
• Made of Eight 2200mAh cylindrical 18650 cells with PCB and poly switch for full protection
• Light weight, compact sizeand higher energy density than any rechargeable battery
• Perfect for HID and Halogen bike headlight (10 - 13W) and can run 4-5 hours. (Power Limit is 110W.Oterhwise, internal PCB will shut-down the battery pack to protectbattery from over-drain)
• Perfect replacement battery forany 13.2V NiMH battery pack and 14.8V Li-Ion battery packs.
  For example: TrailTech Helmet HID Light Kit; Starfire Dual or SingleBeam; Niterider:Headtrip,Storm, Blowtorch
• No memory effect and rechargeable up to 500 times
• Longer storage life than NiMH battery
• Built-in IC chip will prevent battery pack fromover charge and over discharge and prolongs battery life
• Perfect 14.8V battery pack for bike lighting, RC toy, robots,laptop and DVD external battery.
• Use the Universal Smart Li-ion Battery Charger (set voltage at 14.8V) for charging the battery.

  Warnings:

  • CAUTION: when working with Li-ion cells, they are very sensitive to charging characteristics and may explode if mis-handled.
  • User should have enough knowledge on Li-Ion rechargeable batteries in charging, discharging and assembly before use.
  • We are not responsible for any damage caused by misuse or mishandling of these Li-Ion batteries
  • Strongly suggestthat youuse our smart Li-Ion battery charger to recharge the battery pack
  • Never use conventional DC adapter to charge the battery module) We are NOT responsible for any damage that is caused by the misuse of the Li-Ion Battery
  • Please don't make parallel connection with more thantwo modules to avoid uneven charge.
