A123 SYSTEMS AMP20M1HD-A CELL
The A123 Systems AMP20M1HD-A is a high-rate LiFePO4 pouch cell with a nominal voltage of 3.3V, 20Ah nominal capacity and 19.5Ah minimum capacity. The supplied specifications list 200A continuous discharge and a separate 600A discharge pulse lasting 10 seconds.
For custom battery pack evaluation, match both sustained and transient loads to the applicable electrical and thermal conditions. The flat pouch format requires suitable mechanical support, tab connections and cooling. Pulse ratings must be assessed with the intended SOC window, recovery time and duty cycle rather than treated as continuous operating limits.
A123 SYSTEMS AMP20M1HD-A CELL
| Brand / Model | A123 Systems / AMP20M1HD-A |
| Cell Type | High-rate LiFePO4 pouch cell |
| Nominal Voltage | 3.3V |
| Nominal Capacity | 20Ah / 20000mAh |
| Minimum Capacity | 19.5Ah |
| Listed Nominal Energy | Approx. 65Wh, as supplied. For comparison, 3.3V × 20Ah gives 66Wh calculated nominal energy. Neither value establishes usable energy under a specific load. |
| Charge Cut-Off Voltage | 3.6V |
| Discharge Cut-Off Voltage | 2.0V |
| Standard Charge Current | 20A (1C) |
| Maximum Charge Current | 100A (5C); confirm the applicable charging and thermal conditions. |
| 10-Second Pulse Charge Current | 200A (10C) for 10 seconds. Confirm starting SOC, temperature, voltage limit and recovery interval. |
| Maximum Continuous Discharge Current | 200A (10C) Confirm thermal conditions and the applicable manufacturer test protocol. |
| 10-Second Pulse Discharge Current | 600A (30C) for 10 seconds. Not a continuous rating; repetition rate and recovery conditions require confirmation. |
| Dimensions | 7.25 × 160 × 227mm |
| Cell Weight | Approx. 495–496g |
| DC Resistance — DCR | 1.5–3mΩ; pulse method, SOC and temperature require confirmation. |
| AC Resistance — ACR | 0.78mΩ at 1kHz; SOC and temperature require confirmation. Not interchangeable with DCR. |
| Listed Operating Temperature | −30–60°C. Separate charging and discharging limits are not identified in the supplied data; do not treat this as permission to charge below 0°C. |
| Storage Temperature | −40–65°C; storage duration and SOC conditions require confirmation. |
| Reported Cycle Life | 3000 cycles to 80% capacity, as supplied. Charge/discharge rates, voltage window, temperature and retention reference are not provided; this is not a guaranteed result for the listed maximum currents. |
Confirm the applicable manufacturer specification before pack qualification. Maximum current figures must remain tied to their voltage, SOC, temperature and duty-cycle conditions; they are not established across the full listed operating range.
A123 SYSTEMS AMP20M1HD-A CELL
The listed 10C continuous discharge rating provides a high-power evaluation point for a 20Ah cell. Validate cooling, connections and protective limits under the actual pack load.
The supplied pulse ratings are 600A discharge and 200A charge for 10 seconds. Confirm SOC, temperature, voltage limits and recovery intervals before evaluating repeated power events.
The 20Ah nominal and 19.5Ah minimum capacity figures provide separate planning references. The listed flat dimensions support preliminary module layout, subject to drawing and tolerance confirmation.

Evaluate the AMP20M1HD-A against both energy requirements and the actual current profile. The following are potential engineering directions, subject to specification confirmation and system qualification.
To discuss your configuration and required documentation, contact MisenBattery about your AMP20M1HD-A project.
No. The supplied data lists 600A discharge for 10 seconds and 200A maximum continuous discharge. Confirm the applicable temperature, SOC and voltage conditions for both ratings.
They describe different measurement methods. The listed ACR is 0.78mΩ at 1kHz, while DCR is listed as 1.5–3mΩ. Do not substitute ACR for DCR in load calculations; confirm the DC test method and conditions.
That is not established by the supplied information. The reported 3000 cycles to 80% capacity lacks a charge/discharge protocol and temperature conditions, so it must not be presented as a result at maximum current.
