RC Lipo Battery Voltage Checker

The FMS RC Lipo Battery Voltage Checker is a compact voltmeter designed for radio-control aircraft pilots who need to verify cell balance before and after each flight. It connects directly to the battery balance lead and displays individual cell voltages so you can confirm the pack is safe to use.

Upgrade from basic LED indicators

Replacing simple LED status lights with a numeric readout lets you spot a drifting cell long before it causes a mid-air cutoff. The jump is worth it when you fly packs of three cells or more and want to track voltage differences down to a few millivolts rather than guessing from colour codes.

Plug-and-play balance-lead connection

Installation is a single step: insert the checker into the JST-XH balance connector on the LiPo pack and read the display. The only common issue is reversed polarity on non-standard wiring harnesses, which shows zero or erratic numbers and is fixed by re-seating the plug correctly.

Questions about this item

What are the dimensions of the FMSBVT01 voltage checker?

The unit measures 2.5 by 2 by 2 inches, so it fits in a small tool pouch or flight box compartment.

How do you connect the checker to a LiPo pack?

Plug the battery’s balance lead directly into the matching port on the checker; the display powers on automatically from the pack.

Does the FMSBVT01 need calibration or battery replacement over time?

It draws operating power from the LiPo being tested, so there is no internal battery to replace and no calibration routine required.
