2 Times Larger Energy & Perform More StableCloudenegy 24V 150Ah LiFePO4 battery could run two times longer than a 12V 100Ah LiFePO4 battery. Generally 124V 150Ah equals 212V 150Ah which can save time and cost for extra wires to expand the energy and no need to balance the voltage. Cloudenegy 24V LiFePO4 battery better protects the battery performance and prolongs the cycle times and the higher voltage of 24V makes it more stable.Grade A LiFePO4 CellsHighest-level safety based on UL Testing Certificate for the cell inside the battery with higher energy density more stable performance & greater power.Built-in 100A BMSProtect from overcharge over-discharge overcurrent and short circuits with an excellent self-discharge rate.10 Year Lifetime & 1/3 Lighter WeightCloudenegy LiFePO4 battery provides 6000+ cycles with a 10-year lifetime which is more than 5 times the lifetime of a lead-acid battery. Furthermore the Cloudenergy 150Ah 24V lithium battery weighs only 29kg just 1/3 the weight of lead acid batteries more portable and easier to take out in outdoor applications.Support in Series/ParallelOur LiFePO4 batteries can be connected in parallel and in series for larger capacity and higher voltage. We suggest that the Max connection in series is: 2pcs batteries to 48V and the Max connection in parallels is: it can connect multiple batteries and no more than 10 pcs in parallel. Products of different manufacturers cannot be connected in series or in parallel. When the batteries are used in parallel or series the voltage must be the same.
