There are others who will weigh in on this, but here are my thoughts, based on a similar challenge on my boat a few years ago.
1. You probably dont need a two bank charger. If you set up your system with all charging
sources going to bank 1, and an ACR or echo charger to top off the starting battery
, a single
bank charger is entirely adequate.
2. Many sources recommend sizing a shore charger such that a 50% discharged bank can be topped off overnight- say in 10 hours or so. For FLA batteries like yours, that is about 10% of C, or around 45 amps.
3. You can spend lots of money
on a charger, but if you dont want to, there are some less expensive but decent chargers available. Iota
is one, which is what I bought, and just above your price
range (the 55 amp model is just slightly more). If you go with Iota
, get the IQ4 option.
4. This question has been covered many times on this forum - try googling for other points of view. Pay close attention to anything written by Maine
Sail (RC Collins). Always check his web page for guidance before spending money
There are various others whose opinions are well regarded - you get a feel for who's who after a while.
