Lynx Class-T Power In (M10)
Victron Lynx Class-T Power In wiring diagram
M10 Lynx module with two Class-T-fused battery branches, each accepting 225–400 A fuses sold separately. Maximum 800 A through the two fused branches; 1000 A through-busbar rating. Fuse DC interrupt capacity must suit the actual bank. M8 modules do not bolt directly to its M10 joints.

Which Lynx module is this?
The Lynx Class-T Power In (M10) has two fused positive battery branches and a common negative busbar. It is passive distribution hardware: no BMS, contactor, current measurement or remote fuse monitoring is built in. The installation manual, printed pages 2–15, covers this exact module.
Its M10 interconnections do not bolt directly to M8 Lynx modules. The 2024 manual predates the M10 Lynx Shunt; its statement that every Lynx Shunt is M8 is obsolete. Match actual joint sizes when selecting an assembly.
Where do the battery and system cables land?
BATT 1+ and BATT 2+ connect the two battery/string positives through their individual Class-T fuses. BATT 1− and BATT 2− join the common negative rail. BUS+ and BUS− continue to adjacent Lynx modules or the system connection.
These are bidirectional battery paths: charging reverses the normal discharge-current direction. The sketch's input/output arrangement does not make this a unidirectional device. Keep all charger and load connections on the system side of any downstream BMS/shunt. The extra ground connection is not permission to bypass the measuring shunt with a second battery-negative path.
How do 800 A and 1000 A differ?
Printed page 7 lists compatible Class-T fuse sizes 225, 250, 300, 350 and 400 A, purchased separately. With two 400 A fused branches, one module supplies at most 800 A through those branches. The through-busbar itself is rated 1000 A; additional modules do not increase that busbar limit.
Choose each fuse for its battery/string, conductor and equipment limits. Check the actual fuse's DC voltage, interrupt capacity and dimensions against the manual's drawing. Class-T describes a fuse family; it does not by itself verify every lithium bank's fault-current protection. An attached BMS contactor does not replace the fuses.
Which assembly details does the drawing omit?
The manual specifies M10 cable lugs, its illustrated washer order and 33 N·m for the M10 connections. Keep washers above the current-carrying lug contact surface. Leave insulating sleeves/barriers on exposed assembly ends and mount using the housing's fixing holes.
Where parallel batteries are used, follow the battery manufacturer's parallel-bank design; Victron's example uses equal cable lengths. Commission with polarity, fuse seating, connection tightness and cover placement checked. The catalog omits exact fuse part numbers, mechanical lug stacks, BMS control leads and the installation's grounding decision.
