This is my first post, so Hi everybody

I have a 2006 Honda Civic Hybrid with 125k miles on it. I am not the original owner of the car so I do not have much information about its history. I know this is an Insight forum, but HCH II seems to have a similar technology anyway.
The car runs great, but I started to notice some wild SoC fluctuation recently. Then I finally got the IMA check engine light. I have not checked the error code but I am assuming that sooner or later I will need to replace/rebuild the battery.
My car is a US import. I live in Jordan. I wish I could send the battery to
Hybrid-Battery-Repair but I am anticipating a hefty shipping cost. I do not think that is a viable option. The local Honda dealers here are clueless about the hybrid technology and they are usually extremely expensive so that option is not a viable option either. I think the only financially feasible option is to repair the battery myself. I feel comfortable doing that.
I read a lot of posts and articles here and on other websites. I am very thankful to the level of details that is being discussed here by members like JimIsBell and IamIan and Hybrid-Battery-Repair ...etc. I am sure I did not mention some other very well knowledgeable people here.
Let me get down to the issue. What do I need to repair the battery?
-I understood that something like CBA battery analyzer is good.
-I need a charger/discharger.
-I have a multi-meter and the necessary wrenches and .... etc.
-I feel comfortable dealing with the high voltage.
-Can I buy the sub-packs from somewhere? How much do they cost? and where? I do not think I can find them here in Jordan. Of course I understand that I should pay for the extra shipping cost.
-What is the best charge/discharge current?
The cost is a real issue ATM. Do I need both the CBA analyzer and the charger/discharger? I found many chargers/dischargers on eBay. I can get a friend to ship it to me. The charger cost ranges from $35 to $200+. What do I need to exactly look for? 5A+? 10A? 6+ cells balance support? what else?
I do not want to spend more than three weeks at most doing this job. Although the money is an issue, but the time is a more important issue. Is it better to get one good charger/balancer? or maybe multiple cheap chargers/balancers? Maybe instead of asking about what I should get I should say: what should I avoid?
Are there any serious differences between working with an Insight battery and HCH II battery?
Anything else I need to know before I get started?
Can I drive the car during this three weeks period without the IMA battery installed?
Edit:
Which one is better?
Robitronic – Overloader 2 or DuraTrax DTXP4170 IntelliPeak ICE?
