Does anyone use the Battle Born Batteries? If so how many and what kind of results do you get? I love to have battery that I could run a small microwav for short time to heat meals up.
Yes, see my post above. The cost for a good inverter charger and batteries will be in the $4,000 range. We cook with induction burner, run a microwave, and keep a chest type freezer and chest type refrigerator cold off the 200 amp hour battery bank.
You can do the same thing for a lot less--but there are some down sides to conventional batteries. 4 group 31 battery (110 amp hour each), will also give about 200 amp hours usable. Weight of these will be about 320 # vs 60# for LI, space will be twice as much. Number of cycles will be somewhat limited on the AGM or Lead acid batteries, vs 3,000 to 5,000 full cycles for Li. Cost for FLA will be less than $400 for generic group 31's. AGMs will cost in the 2 to 3x as much as flooded lead acid. (so $600 to $800). Some premium brands may be more. another option is golf carts--220 amp hour x 4 in series parallel.
The Li battery takes a special charger, and will not charge properly directly off the outboard. A battery to battery charger is necessary. A small bank (200 amps) is probably not good for starting an outboard, so you will still need a lead acid for start.
Unless you have a very comprehensive knowledge of battery systems, I would advise against using Li batteries--there is a lot of power, and a mistake in wiring or circuitry, might end up with a short circuit and damage to batteries, boat or person.
You can decide if you want to use a modified sine wave inverter (probably not work with induction burner, but will--reduced efficiency and noise, reduced life of microwave--I have used both types. Current is PSW. I prefer Magnum, Master Volt or Victron Pure Sine Wave inverters/chargers. Victron is one which has specific profile for Li batteries.
