We import in bulk, so we offer a low wholesale price. No bargaining, please. Factory-direct quality you can trust.

The 1S charging board works for Lithium batteries 3.7-4.2V (1 cell, but can be used for 2 or 3 cells as well).

Compact board using the TP4056 IC, which generates pulses to speed up charging and protects the battery from overcharge and deep discharge.

Input voltage (charging): 4.5 - 6V (compatible with phone chargers or 1S battery chargers).

When charging with solar panels, connect the positive and negative wires to the marked + and – terminals on either side of the Type-C connector.

Fully charged battery voltage: 4.2V - 4.25V.
