Alphacool 2 in 1 Accessory 13S 48V 40A BMS

SKU CH-PCCF-FA7GS

A 13-series 48 V battery management board rated for 40 A continuous current with over-charge, over-discharge, over-current, temperature and short-circuit protection

  • Injection-moulded sealing resists dust, shock and water
  • Multi-function protection covers over-charge, over-discharge, over-current, temperature and short-circuit
  • ISO, FCC, RoHS, PSE and CE approved for safety compliance
  • Compact design with low temperature rise and consistent charge or discharge current
  • Simple plug-and-play installation connects battery pack to BMS effortlessly

13S 48V BMS for lithium packs

This battery-management board protects 13-series lithium-ion packs at 48 volts and 40 amps. It delivers over-charge, over-discharge, over-current, temperature and short-circuit safeguards in a sealed, waterproof housing. The unit meets ISO, FCC, RoHS, PSE and CE approvals and uses plug-in balance wires for quick connection.

Replaces basic protection boards

The board upgrades from simpler 15-amp or unsealed units to a 40-amp continuous rating with injection-moulded sealing. The jump is worth it when a pack needs dustproof, shockproof and waterproof operation plus consistent charge and discharge currents. It covers configurations from 4S up to 16S, so the same form factor scales with future cell-count changes.

Suits DIY pack builders needing robust sealing

Builders who require communication protocols, active balancing or parallel-module support should look elsewhere because this standard BMS lacks those functions. Users planning currents above 40 amps or cell counts outside the 4S-to-16S range must select a different protection board.

Highlights

  • Injection-moulded sealing resists dust, shock and water
  • Multi-function protection covers over-charge, over-discharge, over-current, temperature and short-circuit
  • ISO, FCC, RoHS, PSE and CE approved for safety compliance
  • Compact design with low temperature rise and consistent charge or discharge current
  • Simple plug-and-play installation connects battery pack to BMS effortlessly

Questions about this item

What physical space does the 13S 48V 40A BMS need for mounting?

The injection-moulded sealed board is smaller than earlier versions, so it fits in tight battery compartments; allow room for the balance-wire harness and the temperature sensor lead.

Which installation step is most often missed when wiring the 13S 40A BMS?

Connect the balance wires in exact cell order before plugging the main power leads; reversing the sequence triggers the protection lockout.

What maintenance does the 13S 48V BMS require over time?

Periodically check the balance-wire connectors and temperature sensor for corrosion or loose crimps; the sealed board itself has no user-serviceable parts.
