Spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy
(energy spikes) in an electrical circuit. Voltage spikes usually happen when the AC/DC adaptor is plugged in, or charge current
is cut off quickly. Multi voltage chargers are made using transformers that may be capable of producing spikes that exceed the
maximum ratings of the Discover AES. You must confirm with the charger supplier that the chargers being supplied:
• meet Discover's recommended charge curve, and
• are not capable of exceeding Discover's maximum terminal voltages.

6.3 Charge Curve

Charge sequence
1. Use Qualification phase for auto-on feature (optional).
2. Charge at constant current to 3.4 Vdc per cell module (Bulk).
3. Maintain constant voltage 3.4 Vdc per cell module (Absorption).
4. Terminate when charge current drops below 2A.

6.4 Discharging
• Turn on battery
• Turn on load
6.5 Storage
Systems should be stored out of direct sunlight under the following temperature conditions:
NOT ALL CHARGERS ARE CAPABLE OF CHARGING
LITHIUM BATTERIES!
During system design CONFIRM that your chosen charger
is not capable of transient spikes that exceed the published
MAXIMUM TERMINAL RATINGS of the battery
Do not charge battery higher than 3.4 Vdc per cell module.
Recommended charge current is 0.5C.
