H1 Battery

Perfect fit!

This battery fits perfectly in the case... speaking of the case..The fitment is great and I love the small form factor.

LILYGO T-Echo replacement battery

The battery in my LILYGO T-Echo went bad. LILYGO only sells an upgrade that is half the cost of the T-Echo. There are plenty of vendors on Amazon that sell a battery with the same physical size and amp/hour rating. There is no way to know the quality of the batteries or if they are fakes. This problem is rampant in the LiPo battery market. It helps to find a company that screens the batteries, and insures the quality. I purchased the H1 battery and can confirm that it fits in the LILYGO T-Echo even though it is physically larger than the OEM battery. The connector on the H1 Battery is the correct size and polarity. The H1 Battery is also reasonably priced. I regularly talk to the people from Muzi Works at local Meshtastic and ham radio meetups, and I know they stand behind their products.

Fast shipping nice products

Super fast shipping. So far so good. I've bought a few items from Muzi and love the product. (Please make an H1 case for the V4). 😁
