GWL/Power Lithium Battery LiFePO4 (12V/20Ah)

The product catalog:
Technical specification - LiFePO4 high power battery 12V 20Ah

Information:
Concerning the 12V LP batteries: The monolithic batteries do not have any PCM (any electronics) inside. They consist of finely balanced cells with identical perfomace at the standard operating range of 11V to 15V. The battery must be managed as a single monolithic 12V block. 
NOTE:
The maximal peak discharge of 200 Amp can be only reached with proper terminal connectors. If the terminals are of low (or ordinary) quality, the maximal current will be lower. The standard cell terminal connectors inside the battery are designed for max 80 Amp. If you require higher currents, you need to open the top cover (lid) of the 12V battery and replace the terminal connectors with bigger terminal connectors (more copper, less resistance). Also the maximal peak discharge may be applied only for a few seconds (less than 5 seconds).
