Lithium Battery Charge Indicator Schematic

Great to be able to charge three batteries at once! Charge status indicator for each battery.

I like the charge indicator

I use these with my Amaran lights. They also have a convenient indicator on the back of the battery letting you know how much charge they have.

I love the USB-C charging port directly on the battery. The charge indicator is also great.

Great battery holds a great charge! and best of all has a capacity indicator :D

Sometimes I even forget the I have to charge this battery. It's an Info-Lithium Battery with 6600mAh at 7.2V and it have a very long life!

This battery is great b/c it has a built in battery charge level indicator. This is great for in-field monitoring of battery level. I am recommending this one to everyone.

Compact but powerful with Lithium battery that last 500+ full power per charge

This lithium battery is very reliable.

Arrived with 55% charge, took 22 hours to charge fully on Pearstone dual charger, but ran my Marshall 7 camera-mounted video monitor for over 4 hours, which was 3 hours longer than earlier non-Panny batteries I bought. The Marshall is a power hog with no battery indicator, so power capacity is an important decision criteria for my use.So, it's very helpful to have the battery strength indicator on the battery itself, although it's often hard to press to engage it. It delays its readout for a moment, then reads up to four LED's to indicate power remaining. I wouldn't trust it past the two lower lights, however, because my monitor shut down after the batteries showed about 25% remaining power when tested on the Pearstone charger/tester (the two lower lights out of four were illuminated).Worked long enough to satisfy me, however, so no complaints. These are Watson brand, about which I know nothing. Neither did I know about Pearstone, which I think I purchased previously. I'm guessing these are generic items branded for B & H. Don't have enough experience yet with using these batts to know how many charges they will accept in their life cycle - too busy with other stuff to keep track anyway.Batts snap into charger plates and snap into standard Sony batt adapter plates. All very nice and snug. Engenders confidence and reliance.I know subsequent charging time was about an hour or so. Lost track of exact time. So, yeah, I would recommend these batts to a friend, even others who are not yet my friends. It should be just fine as a reliable power source. I was very impressed and pleased with its performance, no regrets.
