ISDT PC-4860S 1-8S XT60 Parallel Charging Board – 40A 4-Port

The ISDT PC-4860S is a compact four-port XT60 parallel charging board designed for experienced RC and FPV users who want to connect multiple compatible LiPo batteries to one suitable balance charger. It supports battery configurations from 1S to 8S at the board level, with a maximum input current of 40A, up to 30A per output port and a maximum balance current of 2A.

The PC-4860S combines four power outputs, corresponding balance connections, 32 protective fuses and a CNC-machined aluminum housing in a compact approximately 88 × 58 × 20mm format. An XT60 charging cable and 6S balance cable are included.

ISDT PC-4860S Specifications

What Does the ISDT PC-4860S Do?

The PC-4860S is a LiPo parallel charging board. It does not generate charging power or control the charge cycle by itself. Instead, it connects several compatible battery packs in parallel so that a suitable balance charger can treat the group as one larger-capacity battery of the same cell count.

For example, four compatible 4S 1500mAh LiPo batteries connected in parallel remain a 4S system, while their combined capacity becomes 6000mAh from the charger's perspective. The charger must still be configured correctly for the battery chemistry, cell count, total capacity and appropriate charge current.

This is fundamentally different from connecting batteries in series. Parallel charging keeps the cell count and nominal voltage unchanged while combining capacity.

Four XT60 Outputs for Multi-Battery Charging

The PC-4860S provides four charging outputs, allowing up to four suitable batteries to be connected to the board at the same time. Its main power system uses XT60 connectors, a common connector format across FPV drones, RC airplanes, RC cars and other hobby applications.

The board is rated for a maximum input current of 40A and a maximum output current of 30A per port. These are board limits rather than automatic charging targets. The actual safe charging current must always remain within the limits of the charger, batteries, cables, connectors and every other component in the charging system.

32 Fuses for Additional Circuit Protection

ISDT builds the PC-4860S around a system of 32 fuses to add protection across the parallel charging connections. The board also uses an aluminum housing rather than a basic exposed circuit-board design.

The fuse system is an important protective feature, but it should not be treated as a substitute for correct battery handling. A parallel board cannot make damaged, mismatched or incorrectly connected batteries safe to charge.

Compact CNC Aluminum Housing

At approximately 88 × 58 × 20mm, the ISDT PC-4860S keeps four power outputs and the associated balance connections in a relatively compact enclosure. The aluminum construction also provides a more durable external structure than an uncovered parallel PCB while helping the assembly manage heat during use.

The housing is produced through a multi-stage manufacturing process that includes CNC machining, polishing, sand blasting, anodizing, assembly, inspection and packing.

1S–8S Board Support and the Included 6S Balance Cable

The PC-4860S board itself supports balance connections from 1S through 8S. However, the supplied balance cable is specified as a 6S cable.

If you intend to use the board with a 7S or 8S battery setup, do not assume the included cable automatically provides the required charger-side connection. Confirm the balance-port configuration of your charger and use the correct, properly wired balance lead for the intended cell count.

This distinction is especially important when comparing the PC-4860S with a charger that may physically support 8S batteries but uses a different balance connector arrangement.

What Batteries Can Be Parallel Charged?

Parallel charging should only be used when the batteries being connected are appropriate to charge together. As a general rule, the packs should use the same battery chemistry and the same cell count, and their voltages should be closely matched before they are connected in parallel.

For example, four healthy 4S LiPo packs may be candidates for a parallel charging session when they have comparable voltage and condition. A 4S battery should not be connected in parallel with a 6S battery, and batteries with substantially different states of charge should not simply be connected together to let the board equalize them.

Battery capacity does not have to become a new cell count when packs are connected in parallel. Instead, capacity is additive. When determining charge current, calculate the intended rate from the combined capacity while also respecting the lowest applicable limit in the complete charging system.

Compatible Charger Requirements

The ISDT PC-4860S is not limited to one specific ISDT charger model. It can be considered for use with a suitable balance charger when the charger's power output, balance connection, supported cell count and charging capability match the board and battery setup.

The supplied main charging cable uses XT60. If a charger uses a different output connector or balance-port arrangement, any additional cable or adapter must be correctly wired, appropriately rated and suitable for the intended charge current.

To compare compatible charging equipment, explore the ISDT chargers and charging tools available from CNHL. You can also browse the wider LiPo battery chargers collection for additional charging options.

• Confirm polarity before connecting XT60 power leads.
• Verify that the charger supports the intended battery chemistry and cell count.
• Set charge current based on the combined battery capacity and the safe limits of the batteries and complete charging system.

• Confirm that the balance lead and charger balance port match the intended battery cell count.
• Charge LiPo batteries in an appropriate fire-conscious charging area and never leave the charging process unattended.

FAQ

Is the ISDT PC-4860S a battery charger?

No. The PC-4860S is a parallel charging board. It must be connected to a suitable balance charger, which controls the actual charging process.

How many batteries can the PC-4860S connect at once?

The board provides four output channels, allowing up to four suitable batteries to be connected for a properly configured parallel charging session.

Does the PC-4860S support 8S LiPo batteries?

The board is specified for 1S–8S balance support. However, the included balance cable is a 6S cable, so a 7S or 8S setup may require a different correctly wired balance connection depending on the charger being used.

Can I parallel charge batteries with different capacities?

Capacity alone does not change the battery cell count in a parallel connection, but all connected batteries still need to be appropriate to charge together. For the simplest and most predictable setup, matched batteries of the same model, chemistry, cell count and similar condition are preferable.

Can I connect a 4S and 6S battery together?

No. Batteries with different cell counts must not be connected together in parallel.

Can the PC-4860S be used with non-ISDT chargers?

Potentially, yes. The key requirements are compatible power and balance connections, supported battery chemistry and cell count, and appropriate electrical ratings. Do not assume compatibility based on brand alone.

What is the maximum charging current of the PC-4860S?

The board is rated for a maximum input current of 40A and a maximum output current of 30A per port. These are hardware limits, not recommended charge-current settings for every battery. The actual charge current must also remain within the ratings of the batteries, charger, wiring and connectors.

Does the PC-4860S include the required cables?

It includes one XT60 charging cable and one 6S balance cable, both approximately 150mm long. Additional or different balance wiring may be required for some charger configurations or 7S/8S use.

LiPo Parallel Charging Notice

Parallel charging requires correct battery matching and charging knowledge. Only connect batteries that are suitable for parallel charging, and always verify chemistry, cell count, polarity, voltage condition, connector condition and charger settings before beginning a charge cycle.

Never exceed the limits of the battery, charger, PC-4860S, cables or connectors. Do not charge damaged or swollen LiPo batteries, and never leave LiPo batteries unattended while charging.
