Narrative:

The airplane had been in maintenance (mx) for an integrated drive generator replacement on the left engine and has had electrical and thrust management and other malfunctions on a fairly regular basis. We briefed this as a threat before takeoff. I was the pilot monitoring. Shortly after takeoff; we got an EICAS caution unscheduled stab trim. However; I asked the first officer (first officer) if rotation and control inputs were normal; and he said felt normal. It then went away and never came up again. Then during climb; passing FL190 we had a left electronic engine controller (eec) fail. I asked ATC for a level off at FL200 due to an engine malfunction and they cleared us as requested. They asked us if assistance was needed and I declined. I completed the checklist and by then; we were on the arrival into ZZZ and had passed ZZZ VOR. I asked for holding to call company to see what they wanted us to do. But now we were in the descent and were at 12000 feet and we were unable to keep in contact with ops or [commercial radio] so I decided to continue to ZZZ but complete one turn in holding. ATC cleared us to hold on the arrival and asked if we needed assistance again. I declined. Then the first officer noticed that the flight controls were jerking to the left and right in an un-commanded manner. However; flight path was never in jeopardy.then; the autopilot failed and the first officer was forced to hand fly the hold and no auto throttles available due to the eec malfunctions. Then the integrated flight information system (ifis) screens started to flicker and blank and the cockpit lighting flickered. The first officer and I agreed that continuing to ZZZ as soon as possible was the best course of action. I advised ATC and asked for priority handling into ZZZ for the ILS xy due to electrical malfunctions. He cleared us as needed. Then; we got a descending TCAS RA with a conflicting red target 1 mile ahead and at our same altitude. I advised ATC of the deviation. ATC advised that there was no traffic in the vicinity but to report clear of traffic. I then reported clear at 10000 feet after descending 2000 feet. I told ATC that this was probably associated with all the other electrical glitches that were going on. ZZZ approach then asked souls onboard; fuel; and hazmat. We had lithium batteries on board in the fwd belly and dry ice. We landed ILS xy ZZZ without any more problems and fire trucks were standing by. Tower then asked if we needed assistance and we declined but he did say that the fire chief declared us a class 2 emergency due to hazmat. Mx met the airplane and mentioned that this airplane has had many issues every time it comes through ZZZ. We entered crew rest and are scheduled to fly this plane again tonight.

Title: A wide body flight crew reported multiple electrically induced issues including a probable false RA command. The crew elected to divert and landed normally.
