While I have been looking into LiFe batteries, I still think Trojan T105
provide the best bang for the buck. Cost have come down a little for lithium
batteries, and with industry leaders like Trojan now selling these
batteries(already at better $/AH), I’m expecting reasonable price drops in the
coming years.
For example, a pair of T105 provides 115 usable AH (50% of 230AH @ 12V) for
total price of $280. The Trojan Trillium TR 12.8 110 provides 100 useable
AH (90% of 110AH @ 12V) for a price just over $1,000. If I had to replace my
house bank today, I would go with 4 Trojan T105. Worst case they would last
4-5yrs but likely longer. In 5 years, one should not be surprised to see
lithium prices drop by more than 25% (i.e. a cost saving of about $550 or the
cost of the 4 Trojans).
I know folks who highly recommend the Sam’s Club GC2 Duracell batteries. While
I’m a fan of the Trojan quality, at $90/battery or $360 for 215 usable AH (50%
of 430 AH), the Sam’s Club option is worth looking at especially if one is
considering going with LiFe batteries later rather than sooner. To be fair, if
I was full time cruising, I would weigh the sooner rather than the later.
just my two bits,
Paul
