7.8-15Ah Prof Electric Fishing Reel Battery for Daiwa Tanacom 1200 1000 800 750 500 Seaborg 500MJ, Shimano BeastMaster ForceMaster Leobritz with Charger

I’m very satisfied. I’ve paired the Bat Power with a Tanacom 500 and recently took the duo out sturgeon fishing on the Columbia to get a feel for the capacity of the Bat Power and to familiarize myself with the Tanacom 500. Speaking to the Bat Power, after a full day of a rookie electric reel user working the reel yarding numerous sturgeon the battery was only down a quarter capacity. I was impressed. I’ve been fishing sturgeon, salmon and steelhead on the Columbia for ever and was truly impressed with the ease of operation and convenience and quickness to recharge the battery. The following week I took the combination to Port Hardy , Vancouver Island, British Columbia as part of an annual week long fishing trip that includes serious bottom fishing. Once again the battery reel combination operated impeccably especially in the deeper water fishing for large halibut and huge ling cod. I had power to spare at the end of the day and recharging was a breeze. This battery’s performance under heavy pressure was amazing and made me, my fishing buddy’s and our guide , believer’s.

Battery charged up but the button doesnt seem to work. Still have to test on reel that I have coming. I have used the battery on a 3 day fishing trip and fished the deep of 600 ft and the battery worked great. A few months later when going to reline the reel I recharged the battery but the charge cord got locked on. I was able to get it loose but I must of broke some internal wires. I contacted Bat power and they are replacing it under warranty all I had to do is send them back the battery and charger. Great customer service!!!!!!

Do yourself a favor, spend a little more and get a name brand or deep cycle (even though they’re big, bulky, and heavy). Don’t waste your money on these. The first one I bought died after only 2 hours, it then stopped working after that trip. I was able to get a replacement and I bought a second so I had a backup. Just went two days ago and my first battery died after an hour and the next died after 2 hours. Luckily the boat had an extra battery so my trip wasn’t completely ruined but I had to rent it so that was an extra cost. The absolute ONLY things these had going for them was the compact size and the warranty (after I finally figured out how to do that). Other than that I am not pleased with them at all

I bought the 7.8 Ah BatPower Electric Fishing Reel battery for my Daiwa Tanacom 1000 and used it on a four day deep drop fishing trip out of Stock Island, FL (island before Key West) in Feb 2022. I have fished these trips for years and have always lugged a deep cycle 12 V marine battery. I am not getting any younger so I thought I would try this out to save the weight, and my back. What a GREAT battery! We deep dropped for approximately 13 hours the first day and this battery lasted for 11 hours. I was able to recharge the battery in about 2 hours and used it again the second day for about the same length of time. I filled a 100-quart cooler with fish on this trip and had plenty of power. Yes, this is more expensive than a 12V marine battery but at just under one (1) pound it is well work the money. The battery is easy to use and it even has a USB slot on the back to charge your phone.

I like the compactness of the battery, does not take up a whole lot of room. Battery last longer than I expected and thinking about ordering another for a spare and maybe an additional reel also. Thinking of the cigarette lighter adapter.

Bought two of these batteries for my Tanacom 500 electric reel. They were perfect, at 99 Wh, I could take them on a plane with carry on luggage. (big plus). They also could be directly attached to my reel so no cords to get tangled (a real convenient feature). Was initially concerned they would not have the power to handle halibut fishing in Alaska, but I need not have worried; I brought up several 45# fish in 180 feet of water with power to spare. One of the batteries began to malfunction after an hour or so (glad I had a spare, so no lost fishing time). Although that was disappointing, BatPower's customer service was not, they immediately responded to my emailed concern and exchanged the damaged battery with a new one. No fuss no muss, the way customer service is supposed to be. Will I buy from them again? Yes.

After only using the battery once with my Shimano Plays 4000 reel which worked extremely well, I couldn't unscrew the power cord from the battery. They seemed to have fused together solidly and my attempt to free them damaged the battery. I emailed Batpower with a photo of the battery with the remnants of the power cord stuck inside. Batpower agreed to replace the battery without question! Absolutely first class service! The replacement battery arrived today. Unless I am more stupid than I realise the "tighten and loosen" arrows on the battery screw head appear to be pointing the wrong way round! This could easily result in overtightening when actually attempting to loosen the power cord. BEWARE!

Works great, good for the entire fishing day with my powerful DAIWA Seapower 1200 reel, fast charging up to 100%, even after extensive usage during the last year, resistant to severe saltwater eposure, covered by 1 year warranty.
