Hey gang, I have the following system https://www.explorist.life/2000w-inverter-200-400ah-lithium-200-to-700w-solar-camper-wiring-diagram/ - With this setup should I be able to drop in another 1 or 2 SOK 206ah batteries? Or should I not mix manufacturers? https://www.sokbattery.com/products/12v-206ah-lifepo4-lithium-iron-phosphate-battery-pack
Thanks!
The official answer is to never mix brands or capacities OR ages, i.e., same brand, size and age.
However...
If you can construct a bank such that all batteries are sharing the charge/load within their specifications, then there shouldn't be any significant problems. An installation should be verified by using a clamp DC ammeter under heavy loads and charges to confirm batteries/BMSs aren't being subjected to current above their specs.
