Thread: New Auxiliary Battery search

LiFePO4 is still about $12-1400 for a 100ah (equivalent of 160ah AGM battery in useable capacity)..

i like yellow top or calcium

Hi Ranga, do you have an electric winch fitted, if so, go for a Yellowtop.

If no winch, then a Lead Crystal is your best option.

Lead Crystal batteries can be left unused or uncharged for many months, so they might be better for your specific type of use.

Have a look at the link below and let me know which Lead Crystal you are interested in and I will give you a quote.

BTW, I think you will find the biggest Lead Crystal battery that will fit under your seat is the 6-CNFJ-65, which is a 72Ah battery.

This time, it sat idle for 3 weeks (or I thought) without the solar. No idea what caused it to plunge, given the only draw was the solar regulator LCD panel.

Anyway, should it be kapput, I'm wondering what to replace it with. Is lithium a real option yet? Is lead crystal the real deal? Or do I just grab another tried and tested AGM?

Any suggestions?

Had the same happen to my caravan, 2 x 100 amp batteries connected to solar reg and both went flat, real flat. My regulator turned out to be stuffed and was letting the panels back feed. All fixed with a new regulator
cheers
