Few questions about Motors, Esc’s, HDPE

Is this your first bot? As spinners are Hella dangerous and Shrapnel is one of the baddest in the fw class

[MattLampitt]

It will be the first competitive one that I will enter at an event.. I made a 4wd rambot last year and had it for a while but wanted to go the spinner route now there is more full combat events.

The standard powertool batteries are large and heavy compared to what they are capable of.

Well as been as I have no experience with lipo I’ll definitely take your word for that I just wanted simplicity and to stick to what I know, butf I’m going for the Propdrive 5050 with redbrick setup then May aswell not scimp on the battery.. I’ll pop into the model shop in york tomorrow to see if they have any decent 6s in and chargers. Any pointers on battery makes to avoid or are they all pretty decent?

So Iv been to the model shop, he has a Storm - 5s - 4.2ah - 35c . but it’s £115. I wasnt expecting to pay so much for batteries for a FW.
hobby king have a Zippy Compact - 5s - 4.5ah 35c for £41 what’s your advice on this? Or Is it worth getting two separate lower capacity ones and running weapon and drive of separate battery to relieve stress on a single battery?
then I could just get 2 x 2.7ah ones (weapon one with 35c and drive with 25c).
He also has a Powerpal2 intelegent charger which I will probably buy for £50

Hi Matt,
Never having an active weapon I cannot suggest from experience, however from a personal prospective, I would go with two separate batteries. Two reasons: 1. you can tune the battery to the system requirements, 2. should one system have a problem the other will remain healthy.
As for the charger, you can pick up chargers on ebay quite a bit cheaper that will do the job - try looking at an iMax B6 - these can be bought with an integrated charger or separate.

Hope this helps, regards Cliff

Or Is it worth getting two separate lower capacity ones and running weapon and drive of separate battery to relieve stress on a single battery?

This is a thing I keep on running into time and time again. The Honey Badger 2.2, Shu! and Kaizen used separate batteries to drive their weapons. However, it does mean more weight and more wiring to deal with but the advantage is that independence which means one system isn't dependant on the battery which drives both. However, in my new Beetleweight and Ikari, they use a single battery for both drive and weapon. Less weight but more risky. Depends on what the design calls for ultimately.

[MattLampitt]

points taken.. :-)

what about the Yellow zippy lipos then?? They a decent make to use?

[Ocracoke]

Never used them, so can't say. However, the blue Flightmax batteries I have good experiences with. Only had battery failure after genuinely flattening the LifePO4 batteries I use by over-exerting them.

Team RCC is using the Zippy Compacts for a while now. No complaints there. These do the job fine.

[MattLampitt]

Okay then. Thanks for the info everyone. Looks like I got myself a hobbykong shopping list now then. Haha
