Quick overview

The Vanhunks Live Bait Tankwell (22L) is a compact, battery-powered livewell/bait tank made for kayak anglers who want to keep live bait healthy and ready — without bulky gear or hard wiring. It’s designed to sit in the stern/cargo area of kayaks (and can be used on other boats and jetskies where space and mounting allow) and uses an onboard pump to circulate aerated water and maintain bait vitality.

How it works (simple)

Flip the power switch and a high-flow pump circulates and aerates the water so bait stay active and strong.
An adjustable downspout controls water level and excess drains away.
When finished, use the release/drain valve to empty the tank and rinse it.
The unit runs off a small 6-volt battery (battery and charger not included).

Key specifications (what you’ll actually carry)

Capacity: marketed as 22 L
Dimensions: 51 cm (L) × 43 cm (W) × 34 cm (H).
Empty weight: ~6.2 kg (tank only).
Material: 5 mm polyethylene plastic (durable, UV-resistant).

Quick weight note (practical): 22 L of water ≈ 22.0 kg (1.0 kg per litre). Add the empty tank (6.2 kg) → ~28.2 kg total when full (battery and straps add more). Factor that into kayak payload and stability. (Calculation: 22 × 1.0 = 22 kg; 22 + 6.2 = 28.2 kg.)

What’s included / built-in features

High-flow self-priming pump and watertight power box.
6-volt battery compartment (battery sold separately) and bungee to secure it.
2 vertical cylinder rod holders with mounting brackets fitted to the back of the unit.
Heavy-duty adjustable webbing straps with latch clips to secure the tank to the kayak.
Plastic carry handle, free-flow water channels under the unit for drainage, and an easy access lid.

Practical benefits

Healthier, more active bait — better bait = higher strike rates compared with sluggish bait from a non-aerated bucket.
Cost savings over time (keeping bait alive longer reduces replacement bait purchases).
Integrated rod holders & compact footprint keep your stern organised and leave room for other gear.
Portable & battery powered — no need to wire into a boat battery; simple to load/unload and recharge a small battery between trips.

Installation & usage tips

Mount in the kayak cargo area using the stern scupper holes or lash down with the supplied straps; check that your kayak’s stern area can accommodate the dimensions and the extra filled weight.
Use a dedicated 6V battery designed for marine accessories; secure it inside the battery compartment and bungee as supplied.
Don’t overfill — keep some headspace so oxygenation is effective, and avoid sloshing that could affect stability.
For saltwater bait, fill with local seawater; for freshwater baits use fresh water. Change water if it becomes cloudy or warm.

Care & maintenance

After the trip: switch off, pull the release valve to drain, rinse inside with fresh water, and store out of direct sunlight. Periodically check hoses, the pump, and the watertight power box for corrosion or wear.

Limitations & things to consider

Weight when full is substantial (~28 kg in the example above) — affects kayak trim and transport. Always factor this into your crafts. payload limit.
Battery required (not included) — another item to manage and recharge.
Mount means - ensure safe and securely mounted.

Final Thoughts

If you want an easy, compact livewell that keeps bait lively while avoiding complex wiring, this 22L Live Bait Tankwell is a strong, cost-effective option — especially for anglers who want a turnkey, portable solution that snaps into the craft's stern area and includes rod holders and secure mounting accessories. Just be mindful of the added filled weight and the need for a separate 6V battery.
