$3 for smart lithium battery chargers - on backorder for testing

Community General Discussion

If I can get 30 people interested in buying and testing for a small fee a smart Lithium charger I will order them, please let me know.
This charger has all the necessary protections built into it for safe charging of a single 18650 battery.

If you successfully complete the testing period of six months and inform me of any issues you face with the module, you will immediately be awarded a free second revision when it comes out!

No refunds and no warranty yet, until this product has successfully passed a substantial amount of testing and is available to the general public. You are solely responsible for any damages caused by this device.

Shipping within Australia is only AUD 0.75, overseas prices vary. The module itself costs AUD 3.00.

NOTE: I'm not sure what the appropriate section of the forum is for a request for testers, please inform me if I have posted on the wrong section.

If the product turns out well, I will be looking for investors in order to put a large order through, any investors will get all their money back once the modules have sold, and a 3% royalty on all modules sold.

If anyone needs more details on my business for security reasons, please PM me.

Kickstarter is more appropriate than this forum to sell something to test.

Do you mean the overdischarge protection voltage?

7

Yes.

The low voltage at which the battery is cut off.

8

2.4 volts.

It also includes overcharge protection cutoff, overdischarge protection cutoff, overcurrent detection cutoff, and short circuit detection cutoff.

9

Better to be 3.0V or more for long term reliability of Lithium batteries.

If you can find a relaible soucrce that says discharging a Lithium battery to 2.4V is 'safe' post it here.

This chip is designed for protecting Lithium batteries, and it lists 2.4v.

However, the overdischarge release voltage is 3.0V.
