The protection board is Ryder's PCM-F46.8V 25/50A-NTC-ND design - a full-port (separate charge and discharge) board that prevents reverse-current damage. Absolute maximum charge voltage is 54.6V with continuous charge current limited to 5.0A; continuous discharge is rated at 25.0A. Single-cell protection setpoints include 4.25V over-charge, 2.70V over-discharge, 7.0A charge over-current, 42A and 80A discharge over-current stages, and 160A short-circuit protection. Three-stage temperature protection cuts off charge at 50°C, discharge at 70°C and MOSFET at 85°C. PCB dimensions are 66 × 52 × 17 mm.
FAQ
Q: What is the price of a 48V 20.8Ah lithium battery pack?
A: Factory-direct FOB Shenzhen pricing for this SKU typically ranges from USD 180–240 per piece at MOQ 50, depending on connector, wire length and label customization - request a written quote for exact pricing.
Q: What is the minimum order quantity (MOQ) for custom 48V battery packs?
A: In-platform customization (wire, connector, label) starts at 50 pieces; full custom enclosure or BMS firmware starts at 200 pieces. Sample orders are accepted from 1 piece with a refundable sample fee.
Q: What is the lead time for OEM 48V 20Ah lithium battery orders?
A: Engineering samples ship in 7 business days after deposit; bulk production runs take 25–30 days after drawing approval. Sea freight adds 18–28 days to most destinations; air freight is 5–7 days.
Q: Can Ryder customize the battery for my brand (private label)?
A: Yes. We support full private-label OEM/ODM - your SKU, your label artwork, your barcode, your packaging. A sample fee applies and is fully refundable against your first production PO.
Q: Is this 48V 20.8Ah battery pack safe for air or sea freight?
A: Yes. The pack is UN38.3 certified (UN 38.3, 8th edition) for both air and sea transport. We provide the UN38.3 test summary, MSDS and dangerous-goods declaration with every shipment.
Q: How long does a 48V 20Ah lithium battery last on a single charge?
A: Cycle life is rated at ≥500 full 0.2C charge / discharge cycles to 80% of nominal capacity at 25°C. A typical e-bike consumer using one cycle per day should see 3+ years of usable service before capacity drops below 80%.
Q: Does the pack include a Battery Management System (BMS)?
A: Yes. A self-developed PCM-F46.8V 25/50A-NTC-ND BMS is integrated in every pack, providing over-charge, over-discharge, short-circuit, over-current and three-stage temperature protection.
