21700 AM04

21700 AM04
Same Energy, Enhanced Performance.
The AM04 Is NOW.
AM04 VS JP40:
AM04 offers cooler operating temperatures under high loads.
AM04 has higher discharge rates
with equivalent energy delivery.
AM04 extended operating range (down to 2V per cell).

21700 AM04 Highlights
An awesome cell for cost effective power and energy delivery.
Equivalent energy delivery as the Ampace JP40.
AM04 Differences:
- Higher Discharge Ratings
- Cooler Operation Under Load
- Improved Cell-to-Cell Similarity
- Longer Shelf Life
21700 AM04:
-
160A Discharge (for 2 seconds)
Enabled by game changing low IR.
This means energy can flow out of the cell faster, with better transfer efficiency.
-
100A Discharge (temp limited)
It can deliver 45A continuous without reaching 80°C.
At lower discharge rates, the heat losses are minimal.
-
1500 Cycles at 12a
After 2a charge and 12a discharge testing for 1500 cycles, there will be 80% capacity remaining.

21700 AM04 Internal Design
The AM04 is designed without traditional tabs and instead uses collector plates which are laser-welded to copper or aluminum current collectors, which are thin metal strips extending from the anode and cathode. These collectors are laser welded in an S-shaped pattern to the collector plates before being assembled into in the cell's metal casing, where a spiral laser weld secures the negative collector plate to the cell casing.
AM04 Grading:
