Telecom grade batteries help a lot, assuming they're happy.

We put bigger battery banks out on our remote sites, and I'm more inclined to save the batteries on the very infrequent times we have a multi-day power outage. We also don't get snow, so this is a very rare occurrence. bp <part-15@SkylineBroadbandService> On 11/20/2014 12:57 PM, Josh Luthman via Af wrote: <blockquote> I agree. Even if it's a bigger set of $500 batteries, it's worth a) not going to the tower unplanned and b) not having customer problems.

In order to protect my battery string, I am looking for a low voltage battery disconnect that will disconnect the battery string when voltage drops below ~42V and reconnect it when the rectifier comes back online so the batteries will charge. Any suggestions for a ~20A system? Thanks, Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707 </blockquote> </blockquote> </blockquote>
