DIY Lithium Batteries: How to Build Your Own Battery Packs

The book...... https://www.amazon.com/dp/B06XRKD15B/ref=cm_sw_r_cp_ep_dp_4d31ybNMDNDGF

For a short time the ebook version for kindle/pc/mac/phone/ipad is very very cheap!

Thanks for posting this! This is my book, and I hope that anyone who wants to check it out will enjoy it. So far I've heard great responses from the initial readers, and you can see it's already got very nice feedback on Amazon. I set the price really low (99 cents for the ebook) for a few days so that ES members can get it cheap during the launch, but soon I'll have to put it at a more reasonable price.

Thanks for your support and I hope you enjoy it!
