Very very happy with the Headway 38120 10AH cells ! I got 4 to make a 12v battery pack and they are every better than I expected :) I hooked them up to an inverter and they powered my TV with ease !!! The power of these cells is amazing. They came so fast in the post and so well packed, the quality of every item in the box stunned me, everything was just perfect. 100% top seller & I can't recommend them enough & if you want great service then this is the site you should buy from. Thanks again. Review submitted 02/02/2019.

I previously used 18650 cells in a battery pack for low voltage hi-fi devices. Lithium batteries are a very low noise power source and cost a fraction of the price of a decent audiophile power supply. 18650’s are very cheap but need frequent recharges. So I decided to try larger capacity cells to drive my new SOTM music streamer. This device requires 6–14.5 volts which is handy as two 38120’s output around 6.6 volts. I have been running the streamer on and off for a week and the capacity meter is still reading 100%. My next project will be a four cell pack to drive an amplifier requiring 12 – 14 volts. I will definitely be buying from Eclipsebikes again. Their prices are very good and the batteries extremely well packaged. Review submitted 03/24/2020.
