These tests below only note my personal ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Test Results
This is a decent performing cell that should be available at a lower price. This could make it a good choice for applications where a more expensive high performance cell isn’t needed.
The Samsung 30Q and Murata VTC6 can give you about 12% more run time but they cost about 25% more than the Sinowatt 30SP.
While the datasheet’s 15A continuous discharge rating seems reasonable the 30A ”max instantaneous discharge” rating results in more voltage sag and you must not let the cell get hot (over 75°C). I recommend staying under 15A to reduce voltage sag and increase cell life.
The two cells I tested delivered 3003mAh and 3015mAh. This is good consistency for a China-manufactured cell.
Two cells were purchased for testing by me from Liion Wholesale (Liion Wholesale Batteries | Li-ion battery/cell distributor).

I want to work for the community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery and device tests | Patreon.
