Hi all!

I'm looking for a charger circuit with variable over charge cutoff voltage, alternatively one set to 3.8v cutoff. Anyone aware of such a thing? I'll be charging very small cells with this, say 500mAh or so, to be used as UPS for up to an hour or sowith small WiFi-routers.

Something similar to a standard TP4056 charger circuit with battery over dischargeprotectionand all that would be great, but what not really.

The TP4056 circuits have charge protection circuitry and can supply a maximum of 1A current.
