The Itty Bitty Boom CALB17K is a LiFePO4 lithium bank for high-output car audio. IBB specifies matched grade-A CALB cells, a HELTEC balance board, insulated cell construction and 4S2P bus bars.
IBB rates the platform for systems up to approximately 17,000 watts on heavy bass and specifies a 12.8-14.6V charging range. High-output alternator compatibility depends on the vehicle and complete electrical setup.
