Charging LFP Batteries with Lead-Acid Battery Chargers

CHARGING SOURCE: LEAD-ACID BATTERY CHARGER

Customers may choose to replace lead-acid batteries with lithium models. Most lead-acid battery chargers may be used to charge Rolls LFP batteries if the charger is properly configured to operate within recommended charge current and voltage limits.

Refer to the acceptable charge voltage range for the particular Rolls LFP Drop-in or LFP ESS model.

The pre-programmed voltage settings for AGM or OPzV GEL models may be in line with LFP charge voltage settings and can sometimes be used if direct voltage control is not possible for your charger. However, flooded lead-acid batteries often require higher charge voltage settings. If left configured for charging flooded batteries, the higher charge voltage can trigger the BMS to restrict charging to protect the battery, effectively resulting in a 1-stage charge. If this occurs repeatedly, or the charger cannot be configured at a lower charge voltage, it may be necessary to replace the charger.

Refer to the acceptable charge voltage range for the particular Rolls LFP Drop-in or LFP ESS model.
