Lithium DIY power

Hello all does anybody know what this work fine or would I need a 12v 10amp voltage regulator?

is LifePo4 necessarily better than LIon for the use of heq5, TEC camera, dew heaters, laptop etc ? 

It’s trick as Ali express is not so easy to navigate. Also some battery packs say their nominal voltage is 11.1v which is no good

LiFeP04 are better as they have a pretty flat discharge rate that is ideal for powering scopes and accessories. A much safer technology as well. Not sure how good some of the no name brands are though. 🤔

I use the Tracer battery packs as they are top quality. You can’t get better quality batteries.

Thanks for this. 
a bit out of budget for me unfortunately 

I suppose I could just get the ali express one and see how I go and attach a regulator if needed

Get one with a BMS system if you can as it protects the battery. BMS is a lot more than a voltage regularor as gives over charge and discharge and short circuit protection.

Have a look at this place. They sell the parts to make up your own LiFeP04 battery packs.

Hmm seems more cost-effective to buy from Ali express!
