Qoltec Charger for LiFePO4 AGM GEL SLA batteries, 40A

Stable and safe energy source for all LiFePO4, AGM, GEL and SLA batteries

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.

Discover the Unique Power of Smart Charging with the Monolith Charger

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 stage is the so-called absorption charging, it keeps the charging voltage constant between 14.1VDC and 14.8VDC, 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 13.0VDC and 13.8VDC, 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.

Optimal Performance, Long Battery Life and Minimisation of Costs and Energy Losses

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.

Trust our chargers - enjoy uninterrupted energy

- 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 fuse.

Safety is our priority

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,
SCP protection - it protects against short circuits,
OVP protection - it protects against too high output voltage,
OCP protection - it protects against too high current on the line,
OTP protection - is protection against overheating.
