Product code: 51953
Advanced 20A smart charger with DIP switch for a variety of 24V battery types, including AGM, GEL, SLA and LiFePO4. Three charging stages and active cooling ensure optimal operating conditions and extend battery life. Advanced safety features guarantee safe use. Two fuses included.
Precise Charging with 7 configurations to adapt to different battery types
The Monolith charger is designed to work seamlessly with a wide range of different types of batteries, including AGM, GEL, calcium, SLA and LiFePO4, providing them with a stable and safe energy source and a guarantee that the battery will remain in good condition throughout its lifetime.

Integrated in the intelligent 3-stage charging process for optimum performance of your battery
The Monolith smart charger will charge your battery using intelligent 3-stage charging which involves adjusting the charging voltage and current to the current state of charge of the battery, it consists of 3 stages :
The BULK stage is the identification of the battery and its needs, charging up to 80% of the battery capacity, with a maximum current kept constant and a high voltage,
The BOOST The BOOST stage is the so-called absorption charging, it keeps the charging voltage constant between 28.4VDC and 30VDC, reducing the charging current,
The FLOAT stage is the last charging cycle, a so-called sustained charge in which the battery has already reached 95% of its capacity and gradually reaches 100%, there is a reduction in the charging voltage to a constant value between 26.6VDC and 27.6VDC, the charging current automatically drops to 0A once the battery is charged.
The current charging stage of the battery is indicated by an LED on the charger.
Perfect maintenance of your battery at every stage of charging
Intelligent 3-stage charging has many advantages, above all it can:
- Ensure that the battery is fully and evenly charged, improving performance and battery life,
- Prevent overheating, overcharging or damaging the battery, which improves battery safety and reliability,
- Save energy and costs, as it recuces the loss of energy and time required to charge the battery.
7 different SW combinations, Automatic switch-off, Durable aluminium housing, Active cooling, Fuse included
- Equipped with DIP-switch - this is the charger's component for changing the battery charging settings - it allows 7 different SW combinations to be set, we can adjust the charging mode according to the battery type you have, e.g. charging SLA / gel / AGM / flooded / calcium and LiFePO4 lead-acid batteries, as well as the constant voltage power supply mode,
- 3-stage charging mode - provides much faster, efficient and full charging without the problem of voltage drops,
- Durable aluminium housing - perfectly conductive and corrosion-resistant,
- Built-in active cooling - automatically switches on when charging and protects the charger especially when charging heavily discharged batteries,
- LED indication of charger operation,
- Built-in fuse,
- Features short-circuit, reverse polarity, overcharging and overheating protection,
- Automatic shutdown at the end of the charging process - switches off charging mode and remains in sleep mode when the battery is charged,
- Necessary wiring included and two fuses.

Use of advanced security features
When designing the chargers, we placed safety above all else, which is why the product is equipped with comprehensive safety features, including protection against reverse polarity, overvoltage or overheating. For safety reasons, the input and output of the charger have been completely isolated.
UVP protection - protects against under-voltage at the output,Do you care about the high quality of the product you are buying? Our solutions meet your expectations. Each of the AC-DC chargers we offer is covered by the 24 month guarantee valid from the date of purchase.
