While DC to DC chargers and solar controllers without a lifepo4 setting can be used it is beneficial that all sources of charging are set to lifepo4. New lithium iron phosphate deep cycle battery. 100amp continuous discharge built in Battery Management System. 80% depth of discharge twice the power half the weight of lead acid and 2500 cycles rated to 70% new capacity. These are the same type of cells they use in premium cordless power tools and on the space station (just upgraded last year 2019) Forget 2ah at 18v these batteries have 34 times the power of a standard lithium ion battery pack.
Use a 1000watt inverter and power just about anything. Good for rv, solar, kayak, trolling. 100amp quality bms gives you 1280watts of power.32650 Lifepo4 cells in 4 series and 16 parallel (4s16p) for a total of 64 grade A cells. Beware of Lithium Polymer (weighing about 14lbs per 100ah) cells as they are not fire retardant like the Lithium Iron phosphate cells that are in a Dutchman Battery. Also beware of cheaper batteries that do not state the have 32650 cells as they are more than likely prismatic and most manufactures are steering away from prismatic as they are not as strong as 32650 cells over time. According to all the venders I have talked to out of China small battery packs like 100ah are not good for series installation because it greatly reduces cell life as they are not balanced between battery packs and at higher voltages this is detrimental to the cells.
It is much better that all cells at higher voltages are balanced under the same BMS and a custom pack should be ordered. Contact information sent with battery. Although battery shell is waterproof this battery should be kept as dry as possible as the electronics are vulnerable to moisture.. These cost effective lifepo4 batteries can only be wired in parallel to obtain higher amp hours. They may not be wired in series to obtain higher voltages.
