18650 Rechargeable Li Ion Battery Charger

[3.7 V] 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!

[15.6 lb] li-ion is the way to go.

[1.5 lb] 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.

[240 Wh] 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!

[0.155 lb] Rechargeable lithium-ion battery used for Olympus camera works well everytime.

[0.25 lb] I have several of these that I use as holders for small Li-Ion battery packs on Astronomy equipment. They are well made and hold the equipment securely.

[Lithium-Ion] This battery is an updated version of the 5400mAh. All of the previous versions of Li-ion lasted (my are over 10 years old,) but you never knew how much power was left. This version has LED to let you know. Nice.

[0.165 lb] Solid, reliable replacement Li-ion battery for my Panasonic cameras that require the DMW-BLC12 battery. Brilliant, Watson!

[~2 seconds] I have the larger version of this battery tester but also wanted to be able to test NIMH and Li-Ion 9v batteries. I am very happy with both testers and feel like these are the best on the market. Highly recommended!
