## Description

## Lemania Energy LEM-BLEM 25.0A: smart charger 25A (12/24V)

With factory reference LEM 1224250, the Lemania Energy LEM-BLEM 25.0A is for workshops that need more current: 25 A on 12V batteries and 12.5 A on 24V ones, lead-acid or lithium. Its data sheet covers everything from motorbikes and quads to boats, cars, vans and trucks.
On 12V lead-acid it reaches 450 Ah, but for 12V lithium the data sheet limits it to 230 Ah; at 24V it covers 25 to 230 Ah. If less current is fine, the LEM-BLEM 15.0A (15 A / 7.5 A) shares the same format and picks the voltage by itself.
It draws power from a 220-240V (50/60 Hz) supply.

### Features

- •   Charges at 25 A on 12V and 12.5 A on 24V.
- •   12V lead-acid from 50 to 450 Ah.
- •   12V lithium from 50 to 230 Ah.
- •   24V lead-acid and lithium from 25 to 230 Ah.
- •   Boost programme and mode selection.
- •   Indicator LEDs: lithium, charge, warning, power.
- •   IPX4 protection rating.
- •   185 cm leads with clamps or eyelets.
