dollarnaira:

Do actually know what you are asking?
You need roughly 300 cells. If you haven't built just 3 cells in series before,run!!!

😂😂 before he go put fire for house.

Penuelseun:
wouldn't advise that you play with li-ion cells unless you know what you are doing, it is also a labour intensive task to couple 300+ cells. This was the one I built about 3 years ago, 3s 250ah and 7s 120ah

for here na king you be oh.
Greetings your highness.

Wizyoung:


Thank you for the succinct answers.

I'd love to start building and would really appreciate your help on:

1. How to get the soldering iron you now currently use. The soldering aspect is a major challenge for me. I'm good with soldering onboard but this 18650 has proven to be a major challenge

2. Where to outsource quality cells at affordable prices

3. BMS for my built pack

1. I dropped the link to the store I bought the soldering iron from on this thread.

2. I source for cells locally.

3. I bought my BMS from same aliexpress.

I got the knowledge of how to build it from here and YouTube, all thanks to the likes of dollarnaira, penuelseun, ewizard1.

It's like the bosses here don't want to share info regarding outsourcing of lithium cells in Nigeria.

Where to get or who sells these quality cells?

Insightful answers will be appreciated

Check the voltage as it tries to power the ups. See if there's a rapid voltage drop before the trip.
