Fiskadoro: Can you give some more details on the NIMH setup you have? I have been thinking about doing the same thing but am unsure of which battery / chrager would be best. Not wanting to jack the thread but I have had lead acids fail me before with little warning even when watching the discharge and charge of them WITH a voltmeter.

Any help would be gretaly appreciated!

The battery pack itself is made from 10 NIMH Tenergy D batteries. I found a place that had the pack on sale with the charger.

This is almost identical to what I bought but it's a good $50 more then what I paid for mine:

Prices very a lot and they do occasionally go on sale. Last time I think I used http://www.batteryspace.com/ I'll be looking around to see if I can find you a good deal.

Another option is to make a 12.8v lifepo4 battery pack from the same website $23 per cell need 4 add a small bms to keep from over charge/discharge theres a 5% off coupon for that website somewhere just google it. Would be a good alternative. Would fit in a dry box and if taken care of should last you the rest of your fishing career. I have a 100ah im going to use for my trolling motor but thats overkill for just a finder

Would only advise buying from reputable sellers, most of the lifepo4 batterys on ebay are blems or used so they can be crap, but batteryspace is a good place. I have done a ton of reading up on these batterys so if anyone has any questions shoot me a pm and i can help you out. Yes they may cost a lil more than some NIMH batterys but lifepo4's have almost no voltage sag which i belive helps keep your finder accurate i belive. And if you take care of them should last 10k to 20k 80% discharge cycles, now idk about you but i dont think ill get in 10k more fishing trips in my lifetime let alone 20,000!!

This is what I use to charge my FF battery, it works for both 6v and 12v batteries. I've had it for close to three years now, no issues with it.

A good charger is a beautiful thing.
