Packing	37 V 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-drianed Battery pack is placed in Plastic Enclosure: 220 x120x75 (mm) 10 AWG wire inside to carrying 40A current Two heavy duty cylindral connectors are installed in outside box (Red positive ) to carry 40 amp current
Voltage	37 v (working) 42 V ( peak)
Capacity	8000 mAh ( 296 wh) (174 wh/kg)
Cycle life	>300
Prewired	One PCM with balance function is installed in the battery pack to balance charging and protect battery module from Over discharge beyond 42V Over discharge below 28V Over drained beyond 40 A 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. Charge/Discharge terminal: Copper Barrel Lug terminal attached via Binding Post Barrel Lug terminal size: 0.6"(14mm) L x 0.3" (8mm) W x 0.04" (1mm) H Binding Post size: 0.8"(19mm) Dia x 1.2"(30 mm) L Red Binding Post = Postive Black Binding Post = Negative Must use proper AWG wire guage to match up the max discharge current (40A), Please click here for American Wire Gauge table and AWG Electrical Current Load Limits table. You may consider to DIY with our wire below. 10AWG Red wire and 10AWG Black wire. 12AWG Red wire and 12AWG Black wire. Charge terminal: 5" long Standard Tamiya Male plug

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 1.3A 37V Smart Li-Ion battery charger to recharge this battery pack. The estimated charging time is about 9.2 hours. Warning: Please wait for 30 minutes after charged and allow PCM balancing cells to achieve the best performance Optional for Fire Retardant Bag: 295mmx230mmx75mm. Please click here to buy separately. 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
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 comparision chart to see the advantage of Poly Li-Ion vs NiMH / SLA
Warning	Please note this battery is for R&D use only and NOT for individual customers. 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.
