## Description

## Lemania Energy LEM-BLEM 15.0A: smart charger 15A (12/24V)

The Lemania Energy LEM-BLEM 15.0A (model LEM 1224150) is for workshops and professionals who deal with both 12V and 24V vehicles, from a motorbike or quad to a boat, van or truck. It detects the voltage automatically and charges lead-acid and lithium.
At 12V it takes 50 to 450 Ah in both lead-acid and lithium; at 24V, 25 to 230 Ah. If you want more current, the LEM-BLEM 25.0A gives 25 A at 12V and 12.5 A at 24V, although for 12V lithium it stops at 230 Ah.
It also has a boost programme, a mode selector and lights that flag lithium, charge state and faults.

### Features
