I am in a bit of a pickle. I am trying to build a 24v emergency solar generator. Due to them shutting the bridges down and getting stranded with no gas or power for a week or more. I have some medical stuff, a modem and router, and charger for my power wheelchair that I need to use.
I have 2 of these battery banks with no bms from batteryhookup.com. 25.9v 32ah 828.8wh SPIM08HP 24v POWER Module 7s 4p https://cdn.shopify.com/s/files/1/2398/ ... 1625886189
I want Inverter 2000 or 3000w pure sine. Charge controller maybe a 40-60a mppt? Panels thinking (2) 24v bifactual 450w.
I can read sematics but can not figure out how to make the something work to protect the batteries (assuming I need one)
had a lightbulb moment- could I Perhaps use a active cell balancer instead. Putting a fuse or small miniature circuit breaker after the batteries but before the inverter (200a ?).
I am just worried about discharging the batteries to far. I would like the idea of a low voltage cut off.
All solar places say use a bms
I know that the batteries are small but I need it portable and light
I understand that I should be topping off the lead bricks every day
Can I ask why?
Also does not percot apply to lithium ion? Or just lifepo4?
