Product Description:
The 52V 14Ah (14S × 4P) lithium-ion battery pack is built with high-performance 21700 cells and delivers about 728Wh of energy for longer rides and strong hill climbing.
It's housed in a compact DP-6 slide-rail case with a key lock and LED charge indicator, and it's a great fit for mid-drive and hub-motor e-bike systems that need up to 45A continuous current.
The built-in 45A BMS provides full electronic protection, and the pack is rated for 800+ cycles at 80% or better capacity retention.

How to maintain the battery?
The battery should be stored in a clean, dry, ventilated environment at room temperature. When unused, keep it at 30–50% charge and recharge it every 3 months to prevent over-discharge.
Charging Instructions
The charger's indicator light will display red while the battery is charging. Once the battery is fully charged, the indicator will change to green.
How to prolong your lithium ion battery?
Recharge your batteries before they are completely dead.
After every 30 charges, allow your lithium based battery to completely discharge before recharging.
If the battery cannot hold a charge even after proper charging, it may be time for a replacement.
