It's useful to replace NiMH or another battery powered devices supply. Need some DIY skill and right Lithium cell. Example i'v replaced my Flysky 4×AA cell holder a 4500mAh LiPO cell and this modul. By this mod i'v got a standard USB-rechargeable RC Tx unit. It's work more than a half day long and recharging is less than 2 hours. Very nice and good thing.

very useful for electronics project. You can also boost your battery from 3v up to 27v. very cheap and fast delivery. it working good.

Nice tile to convert battery power to lithium battery. The output voltage can be set over a wide range. The input voltage (chargers) could be higher, at least up to 12V. Normally, a phone charger is used to charge a system that unloads a battery up to 2V, so you have to be careful and quickly charge the battery that is unloaded to that voltage, or you have to reload the system to disconnect the battery a little earlier. In GM328 I used the original battery control of this system and added a proper cut-off to the program.

Fajna płytka do przerobienia zasilania urządzenia z baterii na akumulator litowy. Napięcie wyjściowe można ustawić w szerokim zakresie. Napięcie wejściowe (ładowarki) mogłoby być wyższe, choćby do 12V. Standardowo do ładowania używa się ładowarki telefonu Układ rozładowuje baterię do 2V, więc trzeba uważać i szybko naładować baterię rozładowaną do takiego napięcia, albo przerobić układ aby odłączał baterię trochę wcześniej. W GM328 użyłem oryginalnej kontroli baterii tego układu i dodałem do programu odpowiedni cut-off.

Good board, worked exactly as claimed and made my project easy to power up.
