Exact-fit replacement for Wireless Go II

This Estry lithium cell matches the original Rode NTA552331 and 0442-0053-01 specifications. It delivers 3.8 V and 300 mAh capacity in a single pack. Overcharge, over-discharge, over-voltage and short-circuit protection are built in. The cell measures 27.7 x 23.0 x 6.2 mm and weighs 33.0 g.

Interface limited to Rode Wireless Go II transmitter

The battery only fits the Wireless Go II transmitter; it will not power other Rode models or third-party gear. No charging circuit is included — the transmitter handles charging. Certifications cover ISO 9001, RoHS, CE, UN 38.3 and MSDS. Polarity and connector layout follow the factory design exactly.

300 mAh gives typical Wireless Go II runtime

At 1.18 Wh the cell supports normal recording sessions for the Wireless Go II. Heavy continuous transmission will drain it faster; users planning all-day shoots should carry a spare. The 380 mAh figure noted in supplier data reflects a different test condition. Replacement restores original run time when the factory cell degrades.

Questions about this item

Should I choose the 300 mAh or the 380 mAh version for my Wireless Go II?

The supplier lists both 300 mAh and 380 mAh on the same page; the 380 mAh cell stores more energy (1.18 Wh) and will run the transmitter longer per charge.

What does the 1.18 Wh rating mean for actual recording time on a Wireless Go II?

At 3.8 V the 380 mAh cell delivers 1.18 Wh, which typically powers a Wireless Go II transmitter for several hours of continuous recording depending on gain and RF settings.

Does the battery use a standard connector or a proprietary Rode interface?

It replaces the original NTA552331 / 0442-0053-01 pack, so it uses the exact proprietary connector and form factor (27.7 × 23.0 × 6.2 mm) required by the Wireless Go II.
