    I had ordered one of these a few months back and incorporated it into a charger for a 12.6v/ 20 Ah SLA battery to be used as a back up source to charge my phones, power back up lighting, &c. During a power outage it kept me aware of the charge level of my battery so we could conserve power during the storm. It worked so well I decided to order 2 more; 1 to incorporate into a back up supply I built over a year ago and another to go into my next project. Btw, the display consumes 4.75 ma @

    Fast shipping and delivery in perfect shape ! I tested the product with both SLA (2x12V) and LiOn (7S) battery packs and works perfect as described. When it is used with SLA batteries it takes a few seconds (after first connection) to reach the right capacity value ... Very Satisfied ! Recommended !

    This device is going to be part of my Solar back up power source. It will be used along with a DVM. The advantage to using this device is that you get to see how much reserve capacity is left. It would be nice if the back light would time out but the load on the battery is about 20 ma which is trivial since it will be used with a 20 Ah SLA 12v battery. What I may do is use it with a push button switch to spot check the remaining battery charge. I'll probably use a mosfet device as a one shot

    The device is a battery voltage indicator. Allows you to evaluate the current state, but do not think that the display shows the level of charging. I used to indicate battery voltage in UPS.

    Easy to set up, good measurement, but angle of view is not so good, especially in low light condition.
