It can pull 800 amps continuous (9,600W) and 1200 amps burst (14,400W)! Features unused Lithium Energy Japan prismatic LiFePO4 cells, beefy high discharge ALUMINUM busbars, and heavy-duty bare wire 2/0 aluminum terminal blocks. Perfect for high discharge 12v applications such as lead-acid replacement battery, RV stationary storage, golf cart replacement battery, car audio, and other high performance uses. The lithium iron phosphate (LiFePO4) chemistry is much safer than standard lithium-ion, NMC or LiCoO2 cells. Plz note that the aluminum trapezoidal D-plates (for use with the 2/0 blocks) only come included in the PRO version. Compression plates on the PLUS and PRO may look slightly different than pictured. BattGo balancer is not included, sold separately > HERE.  5-pin balancer cable is included. Available in 3 variants (choose from dropdown menu): BASIC (SLIM): Cells + Busbar (Assembled) PLUS (SLIM): Cells + Busbar + Compression (Assembled) PRO (SLIM): Cells + Busbar + Compression + 2/0 Aluminum Blocks (Assembled), includes aluminum D-plates Battery Pack Specs Busbars:  PCB and Aluminum Cells:  LEV60F Prismatic by Lithium Energy Japan Voltage (nominal):  12v Configuration:  4s2p Typical capacity:  148Ah Current (max burst):  1200A Current (continuous):  800A Power (max):  14,400W burst / 9,600W continuous Weight:  42 lbs Dimensions:  27" L x 5" W x 6" H Cell Specs Brand:  Lithium Energy Japan Form:  Prismatic Type:  LEV60F Voltage (nominal):  3.2v Voltage range:  2v-3.5v Typical capacity:  74Ah Power (max current):  1,780W (600A) at 25° C, SOC 50%, 10sec Resistance:  0.7milliOhms at at 25° C, SOC 50%, 10sec Max charge/discharge current:  180A continuous (at 25° C) Weight:  2.17kg Dimensions:  55mm L x 171mm W x 115mm H Terminal torque: 9Nm +/- 3 / 6.64ft-lb *** IMPORTANT SHIPPING NOTE: Our automatic shipping calculator sometimes underquotes heavy orders. If your order is underquoted for shipping costs we'll send you an edit email to collect the balance due. Only orders that are fully paid for can be shipped out. Need more than 2 sets? Email support@jag35.com to get an accurate shipping price before purchasing. Charging We recommend fully charging this pack as soon as you receive it. Charger not included. NOTE: For any lithium iron phosphate batteries, state of charge cannot be determined by voltage alone, you need to count Amp Hours or Watt Hours. Typical behavior is for the "Resting Voltage" to be 13.2VDC a few hours after your charging session.   For customers who wish to add 2/0 terminal blocks after receiving their battery you can buy them > HERE If adding the 2/0 blocks yourself, you'll need a pair of aluminum D-plates, sold separately > HERE.   USE AS AN EXPANSION BATTERY: This battery pack can serve as an expansion battery for many popular power stations. It may be possible to connect multiple batteries in series to increase the charging speed (Volts), or connect multiple in parallel to increase capacity (AmpHours) and current (Amps), see your device specs for max limits. Plz double-check your power station's PV/Solar input specifications to make sure this battery will be compatible. Use with: EcoFlow Delta Max 2000 (Solar Charging Input 800W Max, 11-100V, 13A).

NEW YORK residents:On 3/2/2023 New York passed a law banning the sale of lithium-ion batteries for mobility devices that are not certified to UL 2271, and the assembly and reconditioning with cells removed from used batteries for commercial sale within the state of New York (more details here). New York residents, you are solely responsible for researching, understanding and complying with all pertinent regulatory rules, laws, statutes, and NY safety standards. Safety is important to us, we don't want people to get hurt or property to get damaged, especially when working with DIY and/or second-life lithium-ion batteries. All batteries everywhere are inherently dangerous, so we urge all who work with DIY and/or second-life lithium-ion batteries to take safety seriously so as to avoid causing any harm to self, others or property.
