Have any of you found a decent off the shelf battery as a replacement for the OTS 12v NiMH battery in the SSB-2010? I could probably build one with spare cells I have lying around, but I was just wondering if there's anything out there that's cheaper than the $150 OTS wants for the official replacement. -------------- next part -------------- An HTML attachment was scrubbed...

All the SSB-2010s (diver units) I've had just used eight regular AA dry cells. They snap into a plastic battery holder that is a generic component, found on Amazon for a few bucks. Let me know if you want photos or something. On Thu, Jul 2, 2026 at 1:11?PM Justin Helland via Personal_Submersibles < personal_submersibles at psubs.org> wrote: > Greetings!

Other failures can occur by charging or discharging beyond the batteries capacity.? Interestingly, the chemical makeup of Lifepo doesn't burn or explode, however it will create so much heat that it initiates combustion in surrounding materials. For submarine use, Lifepo are not plug-n-play like wet-cell or AGM.? They are more temperamental and require a bit of research to understand and source correctly, require a smart charger of appropriate current and voltage, and a battery management system (BMS) to control everything.? The tradeoff is longer power duration and a very large number of recharges before replacement. Building your own battery bank is a great way to learn how Lifepo works and how to reduce risks associated with them.? It also gives you the opportunity to design it for your specific needs and source quality parts. All batteries have potential to be very dangerous.? Back in the 70's we used to see documentaries showing lead-acid wet cell batteries exploding in cars when jumping them.? Whether lifepo is safe for submarine use most likely depends upon how well they've been researched, sourced, and installed for their particular application.
