VEVOR 12V 20A Lithium Battery Charger, 14.6V, AC-DC LiFePO4 Smart Charger, with Anderson Connector, LED Indicator, 0V Activation, for Lithium LiFePO4 Deep Cycle Rechargeable Batteries of Boat, RV
This is a LiFePO4 20A charger, not for lead-acid. 20A is way too big for 10Ah—it will overheat and damage your battery. Please use a 1–2A lead-acid charger.
Can the maximum voltage be adjusted down to limit max charge of the battery to 90%? I am interested in long battery cell life, I would prefer not to charge to 100% SOC.
