About this product
A control board for 12V storage batteries that starts and stops charging automatically using a relay. Two potentiometers, RP1 and RP2, set the voltage at which charging starts and the voltage at which it stops. The compact board measures 50 x 32 x 18 mm.

Frequently asked questions
How do I set the start and stop charging voltages?
RP1 sets the voltage at which charging starts. Turning it clockwise raises that voltage and counter-clockwise lowers it. RP2 sets the voltage at which charging stops. Make adjustments while measuring the battery voltage with a multimeter.
Can I use it with lithium batteries?
The listing specifies it for 12V storage batteries with relay thresholds of 12.4V and 14.8V. It is not listed for lithium batteries, so use it only with the battery type it is specified for.
