OptiMate TM-274 Lithium 4s 10A Battery Charger

The TUNE mode provides a stable power supply when reprogramming vehicle systems, in car showroom displays, and when saving settings when battery cables need to be disconnected to accommodate power-driven accessory systems or when replacing batteries.

BMS reset and button activated: for batteries with resettable low voltage/with protection for deep discharge.

SAVE mode (recovery) of batteries with BMS restart: starts at 0.5 V with continuous monitoring and checking of defective or shorted cells; also the charge acceptance can be verified. Unnecessary (and unsafe) charging of a defective battery is prevented.

SafeT: automatic adjustment of the charging current to the ambient temperature is determined by the charger. Reduced charge with sub-zero temperatures and no load if the temperature is below -20 C (may damage the lithium batteries).

Ampmatic: the microprocessor adapts the current to the ideal load curve of LiFePO4 according to the size and condition of the battery in order to make the load as complete and fast as possible.
