It puts out 20 amps at 14.4V and, importantly, it can wake a battery whose BMS has latched off after a deep discharge — something most generic 12V chargers cannot do because they refuse to start into a zero-volt pack.\u003c\/p\u003e\n\u003ch2\u003eWhy this charger\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e20A output at 14.4V plus or minus 0.2V, which is a correct LiFePO4 absorption target rather than a lead-acid voltage applied to a lithium pack.\u003c\/li\u003e\n\u003cli\u003eThree-stage cycle: pre-charge, constant current, then constant voltage.\u003c\/li\u003e\n\u003cli\u003eRecovers BMS-protected batteries that have shut themselves down, which is the usual reason a lithium pack looks dead.\u003c\/li\u003e\n\u003cli\u003eUniversal 100-240VAC input at 47-63Hz, so it works on shore power, a generator or overseas mains.\u003c\/li\u003e\n\u003cli\u003eM10 terminals plus a 50A Anderson connector, so you can hard-wire it or plug it in.\u003c\/li\u003e\n\u003cli\u003eLED indicators for standby, charging, full and fault — you can tell the state at a glance without an app.\u003c\/li\u003e\n\u003cli\u003eAluminium case with an active cooling fan. Rich Solar describes the fan as quiet; it is still a fan, so this is not a silent charger.\u003c\/li\u003e\n\u003cli\u003eProtected against over-temperature, reverse polarity, short circuit and over-voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow it compares to the 10A version\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe 10A model in this range costs less and charges at half the rate. On a 100Ah battery that is roughly the difference between a five-hour and a ten-hour recharge.\u003c\/li\u003e\n\u003cli\u003ePick the 20A if you turn the battery around daily or the bank is 200Ah or larger. The 10A is enough for occasional top-ups and winter maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation and use\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating range is -4 F to 104 F. Do not charge a LiFePO4 battery below freezing unless the battery has an internal heater — this charger does not check pack temperature for you.\u003c\/li\u003e\n\u003cli\u003eGive the case airflow; the aluminium body is part of the heatsink.\u003c\/li\u003e\n\u003cli\u003eAt 9.06 x 3.58 x 2.07 inches and 3.75 lb it is portable enough to move between vehicles rather than mounting permanently.\u003c\/li\u003e\n\u003cli\u003eMaximum AC draw is 4A, so it is undemanding on a campground pedestal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWarranty\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCovered by Rich Solar's standard limited warranty.
