2S String Anti-overcharge Over-discharge 7.4V Lithium Battery Protection Board
A part of the review has been auto-translated.
Banggood sent me a different item (see the photo) that looks to be an USB power supply. after informing them I had a full reimbursement of the unit I purchased. Thank you Banggood, very well done. I ordered again the anti overcharge circuits hoping to receive the right circuits. Banggood mi ha inviato un oggetto diverso (vedi la foto) che sembra essere un alimentatore USB. dopo averli informati ho avuto un rimborso completo dell'unità che ho acquistato. Grazie Banggood, molto ben fatto. Ho ordinato di nuovo i circuiti anti-sovraccarico sperando di ricevere i circuiti giusti.
Ferfecto is exactly what they advertise.
Everything is well. Time too long to deliver.
Always pleasantly surprised with the quality and options available in these things. Mine work as described. Will likely get more.
