Free QuoteA 3.7V battery is a type of rechargeable lithium-ion battery that operates at a nominal voltage of 3.7 volts. The 3.7V rating stems from lithium-ion chemistries. Lithium supplies around 3V during discharge, so pairing it with appropriate cathodes results in a 3.7V operating potential – the maximum safe level supporting stable performance.
Example: The Gravity 500 Van Charging Station/External Solar Battery has a 135,000 mAh battery, which is equivalent to 500Wh. To compare with a 12V-74Ah car battery, you can calculate the capacity: 12V x 74Ah = 888Wh. How long does it take to charge my portable solar battery?
3.7v sounds like a LiPo battery. LiPo batteries have a nasty habit of bursting into flames when mistreated. That means you need a proper LiPo charge regulator. You will have to choose the solar panel to match the regulator. Yes, it is a LiPo battery.
1x Lipo Battery 3.7v @ 1000mAh. 1x Solar panel (DMM = 6v @ 580mAh). Lets start and say the battery is at 3.0v of charge. The solar panel is not on direct sunlight and it is producing 4.5v @ ~ 430mAh-ish, "open" voltage. 80% Percent of that is were the solar panel has it's MPP = 3.6v @ ~ 344mAh-ish.
Solar panels are rated by voltage and current (V and mA or A). Battery capacity is rated by milliampere-hours (mAh). 3.7v sounds like a LiPo battery.
