What charger for a 13s10p Li-ion battery pack?
Look at your batteries manufacturers charge specifications. 

They will tell you the charger specifics. Some batteries charge faster and heavier than others. 

Also some chargers are constant voltage others are constant current some are pulse or taper up or taper down. 

These charge rates are very important to keep from damaging the batteries themselves. In some instances it might simply harm the batteries' capabilities in others you risk fire and or explosion. 

I have seen those results first hand. Even just the loss of the batteries can be financially devastating let alone fire or worse! 

I know my answer is probably not the technical one that you had hoped for but because of the serious issues involved here PLEASE adhere to the battery manufacturers charge specs!
