Features
(1). Large capacity. 18650 lithium battery capacity is generally between 900mAh - 2600mAh. 18650 lithium battery pack has a large capacity at 12AH
(2). Long life. Cycle life can reach more than 1000-2500times
(3). High safety performance. No explosion, no combustion, no poison, no pollution.
(4). High voltage. Nominal voltage is 48v.
(5). No memory effect. Before charging Do not have to discharge the remaining electricity, easy to use.
(6). Small internal resistance. Greatly reduces the battery self power consumption.
Product applications
Electrical Vehicle,Go Kart.Electrical tool etc.
ODM OEM 12v 24v 36v 48v 60v 72v 30Ah 50Ah 100Ah 240Ah 18650 lithium ion battery pack electric car battery pack li-ion
Product storage
Battery storage environment should be clean, dry, ventilated room, should avoid contact with corrosive substances, should be far
away from fire and heat source.
Pakcaging and Delivery
Mode of transport
The battery is a special product. All batteries need to be tested multiple times before delivery, so the production time is 3 to 7 working days for sample, 25working days for bulk order
Please note: The battery cannot be sent to any island address. If you come from an island address, please contact us before ordering.
