3S Li Ion Lithium Battery Charger Protection Board

li-ion is the way to go.

The Panasonic DMW-BLG10 Li-Ion Battery and Charger Travel Bundle came quickly. I like having a second battery charging while still using my camera.

The Watson NP-BX1 Lithium-Ion Battery Pack and Charger Kit is perfect as a second backup battery. The charger has an easy to see charge indicator light !

Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

Rechargeable lithium-ion battery used for Olympus camera works well everytime.

Given the limits on size and number of Li-Ion batteries you can travel with on a plane this is the charger I have been waiting for: in most use cases it allows you to charge batteries faster than you can discharge batteries - with a few catches. It can draw up to 8 amps so you need a decent circuit to plug into. Also it's not the most inexpensive charger in the Core lineup but I think it could pay for itself with this kind of performance. Recently had a day on Steadicam powering an Alexa 35 with a Teradek Bolt 6LT and Arri focus motor. We were able to rotate between just two 150wh batteries the whole day. It was great. One nit pick: the fuse holder on the back protrudes a bit and isn't the most sturdy. It just got catch on the foam in a case and broke a retaining clip. Easy fix and pretty simple to work around. As long as it holds up this is The One!

The Watson Lithium-Ion Battery is definitely a great choice for those who's original GoPro battery is just not cutting it! I bought this battery to replace the worn out battery that came with my GoPro Hero 3. The original battery was to the point I was lucky to get 2 hours at most, even without the screen attached. With this new battery, I was able to complete an entire overnight Timelapse, note that's without the screen, but even with the screen on it's still a lot better! I would 10/10 recommend this. Did I mention B&H Photo's amazing shipping time!

I bought the EN-EL 14A Lithium-Ion battery for use in BG-N12 Battery Grip for use during a once-in-a-lifetime photo expedition to Maui, Hawaii. The battery held its charge.

I purchased the 3400 mAh Rechargeable Lithium-Ion Battery for my LEDlenser ML6 Lantern so that I would have a spare. The lantern comes with a stock 3000 mAh OEM battery. Using a battery analyzer made for testing of Lithium Ion 18650 batteries, I placed both batteries side by side. I ran four tests that Charged/Discharged and Charged again. I wanted to both exercise the new batteries, as well as compare their performance 3000 mAh vs 3400 mAh. Surprisingly the 3000 mAh battery out performed the 3400 mAh battery by a great deal. This was disappointing to have purchased a top notch battery so I would have extra capacity for my ML6 Lantern. Perhaps the company should question their supplier. The 3400 mAh battery was left in the dust. 3000 mAh LEDlenser Battery 3400 mAh LEDlenser Battery Test #1 3263 mAh 3137 mAh Test #2 3269 mAh 3176 mAh Test #3 3357 mAh 3178 mAh Test #4 3316 mAh 3179 mAh

Watson BP-828 Lithium-Ion Battery is good quality battery, work very good...
