DC electric generating from tegs need diodes anti backflow

[Liam Whoever]

Hello, I have some thermoelectric generation modules which are manufactured to use Seebeck, rather than Peltier, for that. Each of the modules should generate from 1v to perhaps 18v, at up to about 1.8a. I would like to connect all of the positive cables, and all of the negative cables, together at a connector, with an anti-backflow diode on each positive cable between the teg and this connector. Then from this connector on the other side, a positive and a negative lead going to some load, with a diode for anti-backflow on the positive. This positive and negative lead will be rated for more amps as it should carry the combined current from the tegs. All the diodes should be the same model. What is an example of the model diodes which I should get to suit my setup please? I hope to charge a battery from multiple tegs, via a voltage module. Thankyou.
