Hi,

@lewisxhe perhaps?

Can anybody explain the difference between the A7670 and TSIM7600?

I’m interested in battery and solar for a remote location in Canada. Schematics indicate that both have CN3065 for battery charging, both have on-board battery, battery protection

T-SIM 7600 S-8205A for overcharge discharge protection DW01FA for battery management CN3065 for charging ESP32 WROVER JW5222 buck converter ME6217 LDO TCS9208 step-up IO35 for battery voltage

A7670

RS0108YQ20 voltage level converter XC6206P voltage regulator ESP32WROVER DW06D for battery protection CN3065 for charging RT9080 LDO ( or AP2112K )

A7670 seems much cheaper.
