[PSUBS-MAILIST] battery performance

[Alan James via Personal_Submersibles]

 Hi Hank, that sounds great. Are they lifePO4 batteries? I have a 48V 40 Ah battery pack I've been running an inflatable on. They are tricky to monitor while in use and require more than a volt meter. When you have decided whether you want to increase the pack size or not; it pays to get the right electronics to monitor them. I have destroyed a number of smaller lithium batteries, probably through storing them fully charged. Alan

 Hi All,I just want to update my findings with my changes to E-3000.  I am running the sub on a single Lithium 100ah battery with intentions of adding a second.  I may rethink that after my test dive.  The battery performed so well, I may not need the second, or at least not a 100ah.For me it is not the money, but rater the weight.  I ran the sub very hard and travelled pretty far to the dive spot.  I started with 13.8 volts and when I returned home and hooked up the charger  it was at 13.2 volts.  The charge took no time at all either.  I am diving a 60 foot deep lake in a few days and will really run the hell out of it and see how it stands up.
