Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

GODOX AD200 / AD200 Pro — 14.4V Li-ion Replacement Battery (W29)
This is a 14.4V 2900mAh (41.76Wh) lithium-ion battery pack for the GODOX AD200 and AD200 Pro compact strobe lights. It slots into the base of the flash head and powers the capacitor recharge circuit between shots. Voltage and form factor match the original W29 spec exactly.
- AD200 and AD200 Pro compatibility: Both units use the same W29 battery bay, connector pinout, and BMS communication protocol. The AD200 Pro added a faster recycle target but draws from the same 14.4V rail — this cell covers both bodies without modification.
- Bench tested on actual hardware: We ran this cell through repeated full-power capacitor recharge cycles on an AD200 body. The BMS held the discharge curve steady across the session, and the protection circuit tripped correctly at the low-voltage threshold without requiring a manual reset.
- First-fit power cycle on the AD200: After inserting a new cell, power the flash fully off and back on before firing a shot. The AD200's BMS handshake only initialises correctly from a cold start — fitting the battery while the unit is in standby or swapping mid-session can leave the charge controller reading stale state data.
Why AD200 flash output steps down after 10–15 full-power shots
The AD200 capacitor pulls a high recharge current after every full-power discharge. If the cell's internal resistance is elevated — common in aged or deeply cycled batteries — voltage sags briefly during that recharge spike. The flash firmware reads the sag as a low-battery condition and steps output down to protect the circuit. A fresh cell with lower internal resistance holds the voltage rail steady through the same current draw, keeping output consistent across a full shoot.
Recycle time noticeably slower on a brand-new W29 cell
New lithium-ion cells often have slightly higher internal resistance before the electrolyte fully wets the electrode layers — this is normal and not a fault. On the AD200, slower recycle on the first few uses means the capacitor is taking longer to reach full charge voltage, typically around 330V for full power. Running five to ten full-power shoot-and-recycle cycles conditions the cell and lowers resistance measurably. After that break-in period, recycle time drops back to the expected figure for a 14.4V 2900mAh pack.

Frequently Asked Questions
My AD200 output drops noticeably during a sustained portrait session — is that the battery or the flash itself?
That's voltage sag from the battery, not a fault in the flash head. Every full-power shot demands a high recharge current from the cell; if internal resistance is high, the voltage rail dips and the AD200's firmware interprets that as low battery and cuts output. Fit a fresh cell with lower internal resistance and the sag disappears. If the drop still occurs on a new cell, check that the BMS initialised correctly by powering the unit fully off and back on before the next session.
The AD200 recycle time feels sluggish right out of the box — did I get a weak cell?
New Li-ion cells often show higher internal resistance before the electrolyte has fully conditioned the electrode layers. On the AD200, that translates directly to a slower capacitor recharge and longer recycle time. Run five to ten full-power fire-and-recharge cycles and internal resistance will drop measurably. After that conditioning period, recycle time should settle at the level expected for a 14.4V 2900mAh pack.
The AD200 feels warm around the battery bay during a high-volume shoot — is that safe?
Warmth at the battery bay is normal when the capacitor is cycling through rapid recharge draws at full power. The recharge circuit pulls a sustained high current from the 14.4V cell, and that generates heat at the cell itself as well as the bay contacts. The BMS monitors cell temperature and will throttle or cut output if it approaches an unsafe threshold — that protection is working as intended. If the unit feels hot rather than warm, or the BMS trips mid-session, let the flash cool for five minutes before resuming to reset the thermal state.
