Packing	37V 8Ah pack is made by 10 pcs high Power Polymer Li-Ion cell of 3.7V 8000mAh batteries with 40Amp drain capability The state art of PCM is installed the pack to protect battery from over-charged, over-discharged and over-drained Wrapped by heavy-duty heat shrink tube Included 1 pc A Fire Retardant Bag: 295mmx230mmx75mm --- Reduce the chance of damage if caught fire This Fire Retardant Bag (Li-Ion Safer Bag) is intended to reduce the chance of damage in the event of catching fire. Must locate & seal the battery pack in the bag while charging / leaving without any attention
Voltage	37V (working) 42 V ( peak)
Capacity	8000 mAh ( 296 wh) (174 wh/kg)
Cycle life	>300
Pre-wired	One PCM with balance function is installed in the battery pack to balance charging and protect battery module from Over discharged beyond 42V Over discharged below 28V Over drained beyond 40A Must wait min of 30 minutes after battery is fully charged to allow the pcm to perform balance function on all the cells within the pack. Charging terminal: 6" 20 AWG with standard male Tamiya connector Discharging terminal: Discharging terminal:7" 12 AWG wire with standard E-bike connector which fits with BL-600 e-bike kit Red (Large female Pin) = Positive Black (Small female Pin) = Negative
Max. Discharging Rate	40 Amp Limited by PCM
Discharge Curve	The pack has 8Ah capacity measured by Computerized Battery Analyzer with 500W amplifier. (testing voltage: 30V, testing current: 12Amp) Please click here to see the discharge curve of 8 Ah pack at 12A
Dimensions (LxWxH)	6.3" (160mm) x 3" (76mm) x 4" (102mm)
Weight (approx.)	1914 gram ( 4.22 Lb) --- 70 % less weight than NiMH battery pack of 36V 10Ah
Smart Tips	Please use either 37V Li-Ion smart charger below. Smart Charger (1.9A, CE listed, UL approved) for 37V Li-ion/Polymer Rechargeable Battery Pack.The estimate charge time is about 6.3hrs You shall choose our 3.0A 37V Smart Li-Ion battery charger to recharge this battery pack. The estimated charging time is about 4.0 hours. Warning: Please wait for 30 minutes after charged and allow PCM balancing cells to achieve the best performance If you connect two of these modules in parallel, you may build a 37 V 16 Ah Battery pack with a 80 Amp discharge rate with suitable wiring Strongly suggest you put the battery pack into a water / fire resistant box for safety use Optional Quality Multi Departments Bag 5.5x4.5x7.5" for easy carry. Please buy separately here. You may monitor the pack via charging terminal by seperately ordering the 36V battery power monitor with bar mount kit and the connector adaptor.
Applications	Replace 36V NiMH battery pack with much lighter weight for e-bike RC robot and RC aircraft which need high current drain Please see the comparison chart to see the advantage of Poly Li-Ion vs NiMH / SLA
Warning	Please note we are not responsible for any damages or losses caused by misusing Please never discharge the battery pack beyond its Max. rating Please always connect the battery to charger/device with correct polarity.
