Will It Fit My Reel? Electric Reel Battery & Cord Compatibility

Will It Fit My Reel?

Two battery sizes, one cord list. We build cords for Daiwa, Shimano and Banax electric reels. Both the 10Ah and the 5Ah are 14.8V and take the exact same cords — so the only question is your reel's plug.

No Long Cords. Just Freedom to Move.

The battery rides on the rod, so the reel goes where you go. Bow, transom, corners, cockpit — you follow the fish instead of the length of a cord.

Nothing running across the deck to step over at 4am. Nothing to unplug when you swap rods or hand one off. Pick up the rod and the power comes with it.

Compatibility Chart

Every reel family we build a cord for. Three cords cover the fleet, and all three fit both the 10Ah and the 5Ah.

Two Ways To Rig It

Neither one involves a screwdriver. You are on the water in under a minute.

1

Straight To The Reel

Thread the cord onto the reel's power port, hand-tighten the locknut, and go. Fastest setup and the one most people run.

2

Strapped To The Rod

Drop the pack into the neoprene holster, run the velcro sling around the rod blank or the rail, then plug in. Keeps the weight off the reel seat. The 5Ah is the lighter one to hang on a kite rod.

What Comes In The Box

  • The battery, 10Ah or 5Ah
  • Neoprene holster with velcro sling
  • Reel cord in the connection type you select (10Ah)
  • Charger

Power From Dawn To Dusk

Scroll the day. The 10Ah runs a full charter day of drops and comes back with charge in reserve. The 5Ah covers about half that, which is why most kite anglers run it as the second pack.

Power That Lasts

Cylindrical lithium cells picked for cycle life. A management board watching current and temperature on every drop. Machined seals at the only opening in the case. Built the same way in both sizes.

BLACK OAK LITHIUM BO-10000MAH LITHIUM CELL STACK BMS PROTECTION BOARD O-RING SEALED TOP PLATE TWO-PIN CONNECTOR SILICONE CAP
Sealed unit

Battery management system

Watches current draw, cell temperature and the balance across the stack. Load the reel harder than the pack should deliver and it backs off before anything gets hot. Unplug, reconnect, and it resets.

Cylindrical cells, picked for cycle life

Cylindrical cells take vibration and heat cycling better than a pouch. Roughly 500 full cycles before you see 80% of new.

One opening, sealed three ways

Only the top plate comes off, on four waterproofed screws under a silicone gasket with an O-ring beneath. The bottom of the case never opens.

Check It Before You Leave The Dock

No power switch to forget. Plug the cord into the reel and it has power. The button on the side is a fuel gauge. Same on both sizes.


Press to read charge

All four lit is full. Down to the last one and you are finishing the day on borrowed time. Read it on the ride out and you will never be the guy whose reel quits mid-retrieve.

Charge off the included charger between trips. Top it off every few months in the off season and it holds.

Which Battery Do You Need?

Both 14.8V lithium, both IP67, both two year warranty, and both run the same three cords. Capacity and size are the only difference. See all electric fishing reel batteries.

Dropped repeatedly in 800 feet with five pounds of lead through a full day and never felt the power fade. Said the reel ran the same as it did wired to the boat, except he could move around the cockpit.

Straight Answers

Which size should I buy, the 10Ah or the 5Ah?
The 10Ah is the deep drop pack: 10,000mAh and 148Wh, 7¼ inches tall, and it runs a full charter day of drops with charge left over. The 5Ah is 5,000mAh and 74Wh at 4¾ inches tall, and it is the one most people run on kite reels, lighter rigs, or as a backup pack on the second rod. Both are 14.8V, both are IP67, both take the same three cords.
Will this fit my Daiwa Tanacom 1000?
Yes. The Tanacom 1000 runs the DT cord, SKU LB-CORD-DT, on either battery size. On the 10Ah, pick the Tanacom / BeastMaster / Seaborg 300–750 connection type and the cord is in the box.
Does it work with a Shimano BeastMaster 9000?
Yes. Same DT cord as the Tanacom, on 2-pin plug models. Shimano 6-pin reels use a different connector.
Will this fit my Banax Kaigen?
The Kaigen 1000 takes the BX cord, SKU LB-CORD-BX. Banax runs its own connector. Kaigen 1500 owners should call 1-800-348-1287 so we can confirm the plug first.
Will this fit my Daiwa Seaborg 300?
Yes. Seaborg 300, 500, 600 and 750 all take the DT cord. Only the MJ800 and MJ1200 need the MJ cord.
Do the cords fit both battery sizes?
Yes. The DT, MJ and BX cords all plug into either the 10Ah or the 5Ah. The battery end of the cord is identical on both packs, so a cord you already own works on a second battery.
What happens if the reel loads up harder than the battery can deliver?
The management board cuts power before anything overheats. Disconnect, wait a few seconds, plug back in and it resets. The same board handles overcharge, short circuit, temperature and cell balancing.
How is it built to hold up offshore?
Cylindrical lithium cells, around 500 full charge cycles to 80% of new, a management board watching every cell, and one sealed opening. The top plate is on four waterproofed screws under a silicone gasket with an O-ring beneath. The bottom never opens. Both sizes are built the same way.
How does it mount to the rod?
Two ways. Thread the cord straight onto the reel and let the pack hang off it, or drop the pack into the neoprene holster and strap it to the rod blank or the rail with the velcro sling.
What voltage is it?
14.8V nominal on both sizes. The 10Ah is 10,000mAh and 148 watt hours. The 5Ah is 5,000mAh and 74 watt hours. 14.8V is the voltage electric reels are built to run on, which is why the pack plugs straight in with no converter.
How big is it?
The 10Ah is 7¼ inches tall by 2¼ wide and deep. The 5Ah is 4¾ tall at the same 2¼ width.
Do I need to buy a cord separately?
The 10Ah ships with the cord for the connection type you select. The 5Ah connects out of the box. Extra cords are $20 and fit both sizes.
My reel is not on the list.
Call 1-800-348-1287 before you order. The cord list keeps growing and there is a good chance we can match your plug.
