• This Powerful battery pack consist of 20 pcs F Size 13 Ah NiMH Cell in a plastic container
• Protection:
  • 1 pc 65^o Thermostat in charging terminal to protect battery from overcharged
  • 1 pc temperature sensor (BEC Female plug) installed
    • Must connect temperature sensor (BEC Female plug) between battery charger (BEC male connector) and battery pack before charging to protect battery from overcharging or explode. We are not responsible for any damage caused by mis use.
• All Cells are matched before assembling to ensure > 300 cycles service life in 3 C discharging rate
• Impedance of this battery pack is less than 250 mohm.
• The battery pack is designed for hi-power electric bikes. But can be used for any 24V portable DC device
• Perfect for heavy duty walking robots
• Charger:
• For best battery performance, please choose the Powerizer 24V (1.5A) Smart Charger with a temperature sensor to charge the battery. Charging time is about 10 hrs.
• For Faster charger, please choose either CHUN-400 or to Charge time is about 4 hrs.
• Must connect temperature sensor (BEC Female plug) between battery charger (BEC male connector) and battery pack before charging to protect battery from overcharging or explode.
• We are not responsible for any damage caused by misuse or charging with other chargers
• You may make a 48V ,13Ah NiMH battery pack by serial connection of two 24V packs. You must charge two 24V packs separately to get better power balance via a 24V smart charger.

NOTES !!!

• Use only the specified charger provided by Batteryspace, and charge the battery pack with the rapid charge method above, do not over-charge it.
  We strongly suggest using the Powerizer 24V (1.5A) smart charger
• Please do not over discharge below 12V, this may causes a deterioration in the characteristics of the pack.
• Please don't drain the battery over 40 Amp current, which may damage battery permanently.
• Do not airtight storage the battery pack, due to over-charge, short-circuit or over-discharge the pack can leads to the internal voltage increment when safety vent move release the gas to assure security.
• To avoid short-circuit, the battery pack should be equipped with a short-circuit protection equipment in use.
• When the battery pack is put away for storage for more than 6 months, it should be charged and discharged once every 6 months, then storage the pack in a 30% ~~ 50% charged state.
• NOTICE: Any changes made to our battery and charger will VOID warranty.
