● Safe, non-toxic, no rare metals, no explosions or fires.

● Lasts 10x longer (4000-6000 cycles).

● 1/4 the weight of lead-acid batteries.

● Functions from -20 to +75°C.

● Charge anytime without capacity loss.

● Perfect for RVs, ships, home storage, and telecom.

● Supports 1C-105A discharge.

Our technical team conducts meticulous inspections on each cell, checking for physical defects, leaks, voltage,

and internal resistance.


Moreover, a random selection of cells undergoes testing in sets of four to verify their true capacity. Impressively,

all cells surpass the 306Ah capacity threshold.


The Lifepo4 EVE 3.2V 306Ah batteries are authentic, brand-new cells with clear QR codes for easy identification.

M6 studs are welded onto each cell to facilitate assembly. Additionally, each battery shipment includes one copper

busbar and two nuts.


Comprehensive tests have been performed on these 3.2V 306Ah Lithium Iron Phosphate battery cells, including

overcharge, overdischarge, over-temperature, short circuit, drop, crush, and needle puncture. Remarkably, even

under extreme conditions, these cells show no tendency to catch fire, explode, or leak.
