ChargeMe: A Coin Cell Battery Charger.

Support my project:
www.kickstarter.com/projects/...
I make a lot of coin cell powered projects and use the LIR2032 batteries quite regularly. The rated cycle of the LIR batteries are 500 cycles but in reality, it does not last that long. I did a bit of research and found out that the cheap Chinese charger was the culprit. Another thing is that you need to insert two batteries at the same time to charge. The voltage and charge of two batteries will be different and this will eventually ruin one of the batteries.

Is this kickstarter project still ruining or is it canceled ?

[@MohammedRezwanulIslam]

I have shipped to all backers. Now I sell on tindie but Australian post office has stopped shipping economy parcels to overseas. So my store is closed now.

[@IvyPoison]

@@MohammedRezwanulIslam sorry to hear that. I hope it becomes available again. Please PM me when it does as I would love to purchase few of this primarily for personal use, but also for further development and integrations (and also to support the project)

[@MohammedRezwanulIslam]

@@IvyPoison That'll be great. I will let you know.

How much does it cost

Around 50ct if you use a modded TP4056 (20ct/ea for the holder and TP4056, 1ct for the 15k-ish resistor).
