Best Lithium Battery For Solar System

[1x Rechargeable] Best speedlight ever made!!! Namely due to the rechargeable Lithium battery that holds a charge through hundreds of uses.

[Auto] Very happy with the system. Highly recommend solar panels though as it uses battery Fast!

[0.465 lb] Purchased this battery replacement system for use during solar eclipse. It allows tracing the progress toward totality without the worry of low battery power. I will eventually use it for indoor stacked image macro exposures as well.

[6.4 lb] I bought this to initially charge before installation, and then to maintain, 200kwh lithium solar batteries. The unit gets pretty warm and takes a bit to charge them fully, but it finally brings the batteries to the factory recommended charge point. It accommodates lithium batteries with Battery Management Systems (BMS), and it's important that a charger be compatible those systems.

[Yes] I have been using this camera since April to monitor our remote property. I am using Energizer lithium batteries plus solar panel and it has been working flawlessly ever since. Highly recommended for off grid monitoring

[0 to +90°] This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

[4.985 lb] Long lasting Lithium battery makes it cost effective.

[11.1 VDC] I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.

[0.1 lb] 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
