eposes 1974 Posted February 20, 2021 Share Posted February 20, 2021 hi folks , can anyone advise currently restoring my original 1987 Vanessa lunch box.. Recently purchased an F540 4370kv motor+45a esc combo as out of touch with batteries chargers I'm requiring some advise as been out of the scene for a lot of years . * ive original bec controller will this work with this electronic esc? *battery which is best to go for lipo 2s /charger and what does the number with C rating stand for on batteries is this discharge rate ? *lipos can you run them totally flat ? *deans connector what's the other wires plug for on battery? *which makes brands are decent batteries/chargers ? * how long run time is expected with lipo sat 5000amp/hr thanks in advance Quote Link to comment Share on other sites More sharing options...
oodboo Posted February 20, 2021 Share Posted February 20, 2021 Hi, The new esc will have an internal bec. batteries and charger, I’d just find something from a reputable seller that fits my budget but look for hardcase lipos. Modelsport sell a core RC one that fits tamiya cars for about £26. Yes, c rating is something to do with discharge rate, higher c can give more punch on acceleration. Don’t run the completely flat, only down to about 3.6v per cell, the esc will have a low voltage cutoff. The other wires are for balancing the charge on the cells, it’s used by the charger. I’ve been happy with overland batteries from modelsport but the ones I have are a bit of a squeeze in some cars so I’ve got one of the core rc batteries on order. I’ve been using the same basic charger for years. It looks like this but different colour and brand: https://www.modelsport.co.uk/skyrc-e680-ac-dc-80w-charger/rc-car-products/440716. I can tell you I’m happy with what I’ve been using but can’t really comment on other brands that I’ve no experience with. run times on lipos and brushless are much better than they used to be in 1987 and with a 4370kv motor I dare say you’ll need to repair before recharge, that’s going to be one fast lunchie. 3 Quote Link to comment Share on other sites More sharing options...

Thats not a bec its the receiver and it may be best to update the transmitter and receiver to a 2.4 ghz outfit which is more reliable than the old crystal type sets 1 Quote Link to comment Share on other sites More sharing options...
