14.8V 5.0Ah Li-Ion Reel Battery

This replacement power pack delivers 14.8 volts and 5.0 ampere-hours of lithium-ion capacity, rated at 74 watt-hours. It serves as a direct substitute for the Daiwa BM2900 and a long list of SB, LB, HT and Seaborg series packs. The unit fits Daiwa Tanacom 750, Tanacom 1000, Leobritz 500 and Megatwin models. It also matches Shimano BeastMaster 9000, ForceMaster 3000, PLEMIO 3000 and Plays 800 electric reels.

Anglers needing a drop-in Li-Ion pack

Boat and shore anglers who want a single battery that covers multiple Daiwa and Shimano reel part numbers will find this unit convenient. It replaces dozens of legacy codes from SB150J through SB800MJ and LB150 through LB3100N. Buyers who require a different voltage, a higher watt-hour rating or a proprietary connector not listed should look elsewhere. The pack is not intended for non-fishing marine electronics or general-purpose portable power.

74Wh energy capacity decides fit

The 74 watt-hour rating is the single figure that determines whether this pack meets your reel’s power budget. Match this number against the original battery label or the reel manufacturer’s specification sheet before ordering. If the original pack shows a different watt-hour value, the substitute may not deliver the expected runtime. No other specification overrides this capacity check.

Questions about this item

Does the 14.8V 5.0Ah BM2900 battery fit the Daiwa Tanacom 750 electric reel?

Yes, the battery is compatible with the Daiwa Tanacom 750 as well as the Tanacom 1000 and Leobritz 500 models.

How do I install the BM2900 battery into my Shimano Beastmaster 9000, and what step is often missed?

Slide the battery into the reel's dedicated compartment until the locking latch clicks securely; the step often missed is failing to engage that latch fully.

When will the 74Wh Li-Ion pack need replacement under regular fishing use?

Expect to replace the pack after roughly 300 to 500 full charge cycles or when run-time drops below half of the original 5.0Ah capacity.
