We purchased the 12V Dual Purpose 1200CCA cranking and deep-cycle battery to use as our cranking battery. Inside the owners manual’s “Battery Parameters” Section, I noticed that max continuous discharge current is listed as 100A, however the BMS Basic Features Section, subheading “High Current” says it supports 200A continuous current, and can withstand 1200A within 3 seconds.
Im confused as to which of these two values is correct. Is the continuous current 100A, or 200A? WILL THE BMS SAFELY ALLOW 250A??
Our starter is a 28MT model, which has a power rating of 2.9kW., which starts a Perkins 4.236 85-HP Diesel Engine. If my understanding is correct, this starter will require @250A(241.7A) in order to properly work. Since the owner’s manual indicated, within the “Battery Parameters” Section, subheading “Discharging,” the WattCycle 12V Dual Purpose can operate at "1200A@20S/1000A@22S/900A@20S/800A@30S,” I naturally understood this battery would be capable of safely providing the 250A necessary to power our starter.
WILL THIS BATTERY SAFELY PROVIDE ENOUGH CURRENT TO POWER OUR 2.9kW STARTER WITHOUT CAUSING DAMAGE?
This is a REALLY IMPORTANT question as our entire system design hinges on the ability of this battery to SAFELY power the starter.
I appreciate your guidance and full responses to these questions. If the WattCycle 1200CCA Dual Purpose Battery is incompatible with our starter, I need to know before performing the conversion under the existing design.
