I am seeking your advice on what to buy to increase the capacity of by DIY battery bank.
Currently I have a 16S, 48v, 200Ah battery bank with blue CALB cells and a Daly BMS.
I get about 5kWh capacity when I run a capacity test on them.
I would like to ideally have a battery capacity of 10-15kWh.
The options that I see are:
Buy another 12 CALB cells and a Daly BMS for 700 USD -> 5kWh more capacity (I already have 4 cells laying around that I don't use at the moment)
Buy a 10kWh server rack battery for 2200 USD -> theoretically 10kWh more capacity
Important note: I live in Thailand and shippings from China are super cheap and fast to Thailand. Getting products from the US is however very costly and takes a long time.
My stores to buy from are aliexpress.com and lazada.co.th
Additional to either of these batteries, I will need to buy a class T fuse and a busbar to connect the new and the existing battery in parallel.
To connect them safely, I would follow this video from Will.
I will need to buy this from Europe or the US as I did not find either of these products in a Thai or Chinese shop with good enough quality and it will cost be around 150USD.
Given my circumstances and needs, which option would you go for from your experience and why?
Or is there an other, potentially better option that I have not seen yet?
Thank you for your help!
