3Pcs CN3795 MPPT Solar Charger Control for 18650 Lithium Battery 4.2V Charge IoT Arduino LoRa Node Solar Panel Regulator Module

MPPT:

Maximizes energy harvest from your solar panel. It automatically tracks the maximum power point to charge your battery faster and more efficiently than standard PWM chargers, especially in varying light conditions.

All-in-One Safety Protection:

This module comes with built-in overcharge (4.25V) and over-discharge (2.50V) protection. You do not need to buy or wire a separate lithium battery protection board. Just connect the battery directly to the output.

Zero Battery Drain (Anti-Reverse Current):

Equipped with a built-in anti-reverse current diode. When there is no sunlight (nighttime), the module prevents current from flowing back from the battery to the solar panel.

Ultra-low Standby Power: Only ~10uA standby consumption ensures your battery stays charged for longer.

Precise Charging:

Delivers a precise constant voltage of 4.2V (±1%), ensuring your lithium batteries are charged safely to their full capacity without overcharging.
