Must Have Item
Unlike older models, this one contain three really independent charger controllers, each with its own separate power supply channel. Each controller is TP4056-like. It offer high precision, soft recovery of overdischarged cells, low self discharge current, show not connected battery, and other, which today smart charger ICs have. No more need to buy a bunch of power supplies and 1-channel TP4056 PCBs to built the charger suitable for industrial, science, and research quality, not only for toys. Just buy this unit. Final voltage my charger offers is 4.21 volts per section. The unit well designed and have good solder quality.
Notes. 1. My charger comes without power cable, but it is can be easily found separately.
2. This is not a discharging balancer (and does not should to be). It will not fix battery overcharged by other non-precision chargers. Using this unit only, battery life will be maximized.
3. Charge current can be reduced to prolong battery life (by experienced person only!).
Thanks.

Very Good for Science.
Edges are very straight, flat and perpendicular. Cutting without bend. Items are very linear. Will buy again.

Works exactly as i expect.
Very well made unit. Works just out of box. Seller provide all needed screenshots how to tune it, but my unit starts to work immediately. GLONASS satellites shown. Set baud rate to 115200 and save setting also work fine (this is required when number of satellites is high). My test setup: I test it using 'u-center' 19.06 under Linux/Wine, via standard Ethernet-Serial converter (Use u-center's Connection - Network conn menu). This setup also work via Telnet and other standard ways. Note: I do not know how Windows(c)(r) works, and did not test it. Thanks.
