FAQ
Q: What is the actual continuous discharge rating of the Sony VTC5A?
A: According to Sony's official datasheet, the maximum continuous discharge current (CDR) is 25A. The pulse discharge can reach up to 35A (short pulses, typically 5-10 seconds). Please distinguish between continuous and pulse ratings.
Q: What is the difference between VTC5A, VTC5, and VTC6?
A: VTC5A: 2600mAh / 25A CDR; VTC5: 2600mAh / 20A CDR; VTC6: 3000mAh / 15A CDR. The VTC5A offers an excellent balance between capacity and continuous discharge, making it one of the best 25A cells available.
Q: Who is the bulk 100-pack suitable for?
A: The bulk 100-pack is ideal for battery pack assembly factories, power tool repair shops, e-bike conversion shops, and large-scale DIY projects. Bulk pricing offers better value and ensures batch consistency.
Q: Does this battery have a protection circuit?
A: No. This is a bare, unprotected cell. When assembling battery packs, you will need to add a BMS (Battery Management System) for over-charge and over-discharge protection.
Q: How can I confirm this is an authentic VTC5A?
A: Genuine VTC5A cells have a Sony QR code on the top, and the internal resistance is typically between 12-16 milliohms. Fakes often have higher IR or poor build quality. This product is labeled "Genuine" and has been professionally tested.
