BATTERY PACKS FOR ELECTRIC BICYCLES

Lithium Iron Phosphate batteries are the latest and safest battery technology. The batteries listed here are manufactured to the highest quality standards. One third of the weight of lead acid batteries with many times the life span. The batteries we stock can often be a direct substitute for the SLA batteries of the same size. Sure they are expensive but the total cost of ownership is less when all of the benefits are calculated.

These battery packs are made from standard 18650 (C sized cylindrical) cells connected in series and parallel into robust packs. Each pack has an electronic system to prevent overcharge and overdischarge which is crucial for LiFePO4 lifespan. However it is still important that applications do not exceed the recommended limits for long life.

• Safe technology, will not catch fire or explode with overcharge
• 5-10 times the cycle life of lead acid
• double the usable capacity of similar Amp hour SLA batteries.
• flat discharge curve means maximum power till flat.
• up to 3C continuous, 5C pulse discharge. (C = rated Ah capacity)
• can be left partially discharged for extended periods without harm, unlike SLA.
• chargeable using most CC/CV chargers (check with us for compatibility)
• 12.8V nominal, 8V maximum discharge, 14.2V maximum charge voltage
• can be connected in series for higher voltages up to 38.4V
• High quality battery with 12 months warranty in approved applications

The quality of these batteries is obvious from their construction, no gobs of silicone, gaffer tape or shrink wrap like some other imports. Sturdy plastic cases and quality electronic protection and cell construction ensure a long life, peace of mind and value for money. Please compare. We also stock specialized chargers in a range of output voltages to suit these batteries.
