Hi
I plan to use 4 x 9V batteries NiCd or NiMH (in series) to power-up my circuit which needs 12V and 36V. Each battery is rated 300mAh. If required, I can go for more expensive Lithium-ion batteries which are rated 500mAh.
1. Can I use 36V battery charging circuit to charge all 4 batteries simultaneously?
2. Will there be any difference in circuits for 3 x 12V SLA batteries and 4 x 9V NiCd batteries?
3. How much should be the charging voltage and current?
